+<h2><span>INTRODUCTION</span></h2>
+
+<p>When I took charge of the Georgia Room, in
+the Confederate Museum, in Richmond,
+Virginia in 1897, I found among the De
+Renne collection an engraving of the
+pleasant, intellectual face of Commodore
+Matthew Fontaine Maury, so I went to his son, Colonel
+Richard L. Maury, who had been with his father in all
+his work here, and urged him to write the history of it,
+while memory, papers and books could be referred to;
+this carefully written, accurate paper was the result.</p>
+
+<p>At one time, when Commodore Maury was very sick,
+he asked one of his daughters to get the Bible and read
+to him. She chose Psalm 8, the eighth verse of which
+speaks of "whatsoever walketh through the paths of the
+sea," he repeated "the paths of the sea, the paths of the
+sea, if God says the paths of the sea, they are there, and
+if I ever get out of this bed I will find them."</p>
+
+<p>He did begin his deep sea soundings as soon as he
+was strong enough, and found that two ridges extended
+from the New York coast to England, so he made charts
+for ships to sail over one path to England and return
+over the other.</p>
+
+<p>The proceeds from the sale of this little pamphlet
+will be used as the beginning of a fund for the erection
+of a monument to Commodore Maury in Richmond.</p>

+
+<h2><span >TORPEDOES</span></h2>
+
+
+<p>Torpedoes as effective weapons in actual
+war were first utilized by the Confederate
+navy, and Captain Matthew F. Maury introduced
+them into that service, and continually
+improved and perfected their use until
+they had become the mighty engine of modern warfare
+and revolutionized the art of coast and harbour defense.
+He, it was, who in 1861 mined James River, who, in person
+commanded the first attack with torpedoes upon the
+Federal fleet in Hampton Roads, and it was the development
+and improvement of this plan of defense which held
+the enemy's ships throughout the South at bay, and
+caused the loss of fifty-eight of the ships, and the Secretary
+of the United States Navy to report to Congress in
+1865 that the Confederates had destroyed with their torpedoes
+more vessels than were lost from all other causes
+combined. Their use was soon extended from James
+River to the other Southern waters by eleven young
+naval officers, active and alert, who planted, directed and
+exploded torpedoes wherever there occurred favorable
+opportunity, and with a daring and coolness never surpassed;
+officers whose ability was abundantly shown by
+the remarkable inertness of the United States Navy after
+they had left that service in response to the call of their
+States to come and help protect their invasion.</p>
+
+<p>Hardly had Captain Maury arrived in Richmond than
+his active mind was directed to the problem of protecting
+the Southern coasts. The South had not a single
+vessel of war, and but scanty means of making, equipping
+or manning one; the North had all the old navy
+fully armed and equipped, with unlimited means for making
+more.</p>
+
+<p>Penetrated as the country is by innumerable navigable
+waters, and save at the entrance of a few of her largest
+rivers, altogether unfortified, he urged that the only
+available defense was to mine the channel ways with torpedoes,
+floating and fixed, which should be exploded by
+contact or by electricity, when the enemy attempted to
+pass. At that time there was nothing save a few shore
+batteries to prevent any ship whose captain was bold
+enough to run past their fires from ascending James
+River to Richmond, or from reaching any other maritime
+town in the South. Fortunately there were but few bold
+enough for the attempt.</p>
+
+<p>In the beginning there was much prejudice against
+this mode of warfare, which, notwithstanding, has since,
+under Captain Maury's instruction, become the chief reliance
+of most maritime nations. It was considered uncivilized
+warfare thus to attack and destroy an unsuspecting
+enemy, and the United States, and many of her
+naval officers were specially loud in their denunciations
+of those who resorted to it. There was official apathy
+too, and opposition of friends, but regardless of such, he
+proceeded to experiment and demonstrate, and with such
+success that in time the nations of Europe became his
+pupils, and there were hosts of followers and fellow-workers
+at home, and the Confederate Congress appropriated
+six millions of dollars for torpedoes.</p>
+
+<p>His initial experiments to explode minute charges of
+powder under water, were made with an ordinary tub
+in his chamber at the house of his cousin, Robert H.
+Maury, a few doors from the Museum in Richmond, Va.
+The tanks for actual use were made at the Tredegar
+Works, and at the works of Talbott and Son on Cary
+Street; the batteries were loaned by the Richmond Medical
+College, which also freely tendered the use of its laboratory.
+In the early summer of 1861 the Secretary of
+the Navy, the Governor of Virginia, the chairman of the
+Committee of Naval Affairs, and other prominent officials
+were asked by him to witness a trial and an explosion
+of torpedoes in James River at Rocketts.</p>
+
+<p>The torpedoes were composed of two small kegs of
+rifle powder, weighted to sink a few feet below the surface.
+They were fitted with hair triggers and friction
+primers, and thirty feet of lanyard attached to the triggers
+connected the keys. When in use they were to be
+set afloat in the channel way as near as possible to a
+vessel and to drift down with the current until the connecting
+lanyard fouled the anchor chain, or the bow of
+the vessel and the kegs swung around against her side
+when the tightened lanyard would fire the trigger and
+cause the torpedo to explode. So the Patrick Henry's
+gig was borrowed, with a couple of sailors to pull, and
+the torpedo having been embarked, with the trigger at
+half-cock, Captain Maury and the writer got on board
+and were rowed out to the buoy just opposite where the
+James River Steamboat Company's wharf now is, where
+the invited spectators stood to witness the explosion.
+The triggers were then set, the kegs carefully lowered
+into the water, taking great care not to strain the lanyard,
+all was cast off, the boat pulled clear, and we
+waited to see the torpedo float down until the buoy was
+reached, the lanyard foul strain and explode the torpedo.
+But there was delay, the lanyard fouled the buoy all
+right, the kegs floated past and strained the lanyard, but
+there was no explosion. Impatient we backed water to the
+buoy and the writer leaned over the stern and caught the
+lanyard to give the necessary pull, but in the very act
+the explosion took place, a column of water went up
+twenty feet or more, and descending, gave us a good
+wetting and filled the surrounding water with stunned
+and dead fish. The officials on the wharf applauded and
+were convinced, and that the experiments might continue
+Governor Letcher loaned power, and shortly after
+the Naval Bureau of Coast, Harbour, and River Defense
+was organized with ample funds for the work, and the
+very best of intelligent and devoted young officers as
+assistants and an office was opened in Richmond at the
+corner of Ninth and Bank Streets, where Rueger's now is.</p>
+
+<p>In a few months he had mined James River with fixed
+torpedoes to be exploded by electricity should the enemy
+attempt to pass, and a means thus indicated to protect the
+city. During the summer and fall attacks were made
+upon the Federal squadron at Fortress Monroe, under
+the personal command of Captain Maury from Norfolk.
+The first of these was early in July, 1861, from Seawell's
+Point, at the mouth of the James River, and was directed
+against two of the fleet there&mdash;the "Minnesota" and the
+"Roanoke." Friday and Saturday night he sent an officer
+in a boat to reconnoitre, but there was a steam
+picket on watch, Sunday as he was spying them through
+a glass, noting their relative positions, he saw the church
+flag on two of them, a white flag bearing a cross displayed,
+flying just a little above the ship ensign. When
+he thought that those men were worshipping God in
+sincerity and truth, and, no doubt, thinking themselves
+in the line of their duty, he could but feel for them
+when he remembered how soon he might be the means
+of sending many of them into eternity. That night the
+attacking party in five boats set off about ten o'clock.
+Captain Maury was in the first boat with the pilot and
+four oars. Each of the others manned by an officer and
+four men carried a magazine with thirty fathoms of rope
+attached. These magazines were oak casks of powder
+with a fuse in each. Two joined by the rope were
+stretching across the ebbtide and when directly ahead
+of the ships were let go, and floating down the rope
+caught across the cable, the torpedo would drift and the
+ship strain the trigger, ignite the fuse and explode. "The
+night was still, calm, clear, lovely." Thatcher's comet
+was flaming in the sky. We steered by it, pulling in
+the plane of its splendid train. All the noise and turmoil
+of the enemy's camp and fleet was hushed. They had
+no guard boats of any kind, and as with muffled oars we
+neared them we heard seven bells strike. After putting
+the torpedoes under one ship the boats that carried them
+went back, and Captain Maury with the other two,
+planted the other torpedoes. They then rowed away and
+waited, but the explosion did not come and the enemy
+never knew of the attempt. Lieut. R. D. Minor, one of
+his skilful and daring assistants, commanded the second
+expedition which he thus describes:</p>
+
+
+<div class="blockquot">
+<p class="ralign5">C. S. S. Patrick Henry,</p>
+
+<p class="ralign5">Mulberry Point, October 11th, 1861.</p>
+
+<p>Sir,&mdash;Owing to an unexpected delay in the completion
+of the magazine I was unable to leave Richmond
+before the morning of the 9th, and did not reach this ship
+until yesterday about 8 A.M. when I laid your plan
+of the intended attack on the United States ships at
+anchor off Newport News before Commander Tucker,
+who with Lieutenant Powell, the executive officer, placed
+every facility at my disposal for carrying it into execution.
+Acting Master Thomas L. Dornin and Midshipman
+Alexander M. Mason, having volunteered to accompany
+me, the evening was passed in preparing the magazine
+and in explaining in detail to the officers the manner of
+handling and working them. In filling the tanks I found
+that I would have 392 pounds to operate with, instead of
+400, which I had calculated upon; and to insure them
+from sinking I had some cork attached to the buoys,
+which subsequently proved of great advantage. The day
+was a stormy one, with a fresh breeze from the northward
+with rain and mist well suited for our operations against
+the enemy. About sunset Commander Tucker got underway
+from his anchorage off this place, and with lights
+shaded steamed slowly down the river on a strong ebbtide
+till the ships were seen ahead of us, when we came
+to within a mile and a half of the point, dropping the
+anchor with a hawser bent on to it to prevent noise from
+the rattling of the chains. The boats were then lowered,
+the magazines carefully slung, buoys bent on at intervals
+of seven feet, and when all was ready the crews armed
+with cutlasses took their places, and were cautioned in
+a few words by me to keep silent and obey implicitly the
+officers. Acting Master Dornin with Midshipman Mason
+took the left side of the channel, while I took the right
+with Mr. Edward Moore as boatswain of the ship to
+pilot me. Pulling down the river some 600 or 700 yards
+the boats were then allowed to drift with the rapid ebbtide,
+while the end of the cork line was passed over to
+Mr. Dornin, and the line tightened by the boats pulling
+in opposite directions. The buoys were then thrown
+overboard, the guard lines on the triggers cut, the levers
+fitted and pinned, the trip line made fast to the bight at
+the end of the lever, the safety screws removed, the magazine
+carefully lowered in the water, where they were
+well supported by the buoys, the slack line (three
+fathoms of which was kept in hand for safety) thrown
+overboard, and all set adrift within 800 yards of the ship,
+and 400 yards of the battery on the bluff above the point.
+So near were we that voices were heard on the shore
+and Mr. Moore reported a boat about 100 yards off,
+which, however, I did not see, being too much engaged in
+preparing the magazine for its service. Pulling back a
+short distance and hearing no explosion we returned to
+the ship which we found cleared for action and ready to
+cover us in event of being attacked, and the boats had
+just been hoisted up when signal lights were observed
+flashing in the vicinity of the point with considerable
+rapidity, indicating a suspicion on the part of the enemy
+that an attack of some kind was intended. Leaving
+our anchorage, we steamed rapidly up the river and took
+up our former position off this place about 12:30 at night.
+On going to the crosstrees this morning two ships were
+seen at anchor off the point, and later in the day when
+seen from Warwick River, where Commander Tucker
+and I went to get a better view of them, they were apparently
+unharmed, and I concluded that the magazine
+could not have fouled them, though planted fairly and in
+good drifting distances and with an interval between of
+some 200 feet, perhaps somewhat less as the line became
+entangled slightly while playing out.</p>
+
+<p>I have thus minutely described to you, sir, the whole
+operation, believing, as its originator, it would be interesting
+to you, and, perhaps, serve as a guide in the further
+prosecution of this mode of warfare.</p>
+
+<p>I beg leave to return my sincere thanks to Commander
+Tucker, Lieutenant Powell and other officers and
+men of the "Patrick Henry," for their hearty co-operation,
+and I particularly desire to call your attention to the
+coolness and bravery of acting Master Dornin and Midshipman
+Mason, and the boat crews associated on duty
+with me.</p>
+
+<p>I am, sir respectfully your obedient servant,</p>
+<p class="ralign5">R. D. MINOR, <br />
+Lieutenant C. S. Navy.<br />
+Commander M. F. Maury, C. S. Navy,<br />
+Fredericksburg, Va.</p>
+</div>
+
+<p>The torpedoes used by Captain Maury in his attack
+upon the "Minnesota," at Fortress Monroe, and by Lieutenant
+Minor upon the "Congress," off Newport News,
+were as follows: They were in pairs connected by a span
+500 feet long. The span was floated on the surface by
+corks, and the torpedo, containing 200 pounds of powder,
+also floated at a depth of twenty feet. Empty barregas,
+painted lead color, so as not readily to be seen, serving
+for the purpose.</p>
+
+<p>The span was connected with a trigger in the head of
+each barrel, so set and arranged that when the torpedo
+being let go in a tideway under the bows and athwart
+the hawser had fouled, they would be drifted alongside,
+and so drifted would tauten the span and set off the
+fuse, which was driven precisely as a ten second shot
+fuse, only it was calculated to burn fifty-four seconds,
+because it could not be known exactly in which part of
+the sweep alongside the strain would be sufficient to
+set off the trigger. That they did not explode was attributed
+to the fact that the fuse would not burn under a
+pressure of twenty feet of water, which conjecture was
+confirmed by after experiments, when it was found that
+the fuse would very surely at a depth of fifteen feet but
+never at twenty. Sometime after these torpedoes were
+found down the bay by the enemy. Spans, barrels,
+barregas and carried to Washington&mdash;thus the enemy
+forewarned, forestalled further attempts of this character
+by dropping the end of his lower studding sail
+boom in the water every night, and anchoring boats, or
+beams ahead.</p>
+
+<p>To obtain insulated wire, of which the South had
+none, an agent was sent secretly to New York, but without
+success, and as there was neither factory nor material
+for its manufacture in the Confederacy, the difficulties of
+preparing electrical torpedoes, to which Captain Maury
+attached the most importance and greatly preferred,
+seemed insuperable, until by a remarkable piece of good
+fortune, in the following spring, it happened that the
+enemy, attempting to lay across Chesapeake Bay were
+forced to abandon the attempt and left their wire to
+the mercy of the waves, which cast it upon the beach
+near Norfolk, where, by the kindness of a friend, it was
+secured for Captain Maury's use. With part of this he
+connected his mines in James River, below the obstructions,
+with the shore stations, which afterward destroyed
+the "Commodore Barney," and later the "Commodore
+Jones," and with part enabled other Southern ports to
+be similarly protected.</p>
+
+<p>Of his James River torpedoes, Captain Maury thus
+reported to the Secretary of the Navy:</p>
+
+<div class="blockquot">
+<p class="ralign5">Richmond, June 19th, 1862.</p>
+
+<p>Sir,&mdash;The James River is mined with fifteen tanks
+below the Iron Battery at Chaffin's Bluff. They are to
+be exploded by means of Electricity. Four of the tanks
+contain 160 pounds of powder, the eleven other hold 70
+pounds. All are made of boiler plate.</p>
+
+<p>They are arranged in rows, as per diagram, those of
+each row being thirty feet apart. Each tank is contained
+in a water-tight wooden cask, capable of floating
+it, but anchored, and held below the surface from three
+to eight feet, according to the state of the tide. The
+anchor to each is an eighteen inch shell and a piece of
+kentledge so placed as to prevent the barrels from fouling
+the buoy ropes at the change of the tide. Each shell
+of a row is connected with the next one to it by a stout
+rope thirty feet long, and capable of lifting it in case the
+cask be carried away. The casks are water-tight, as are
+also the tanks, the electric cord entering and returning
+through the same head. The wire for the return current
+from the battery is passed from shell to shell and along
+the connecting rope, which lies at the bottom.</p>
+
+<p>The wire that passes from cask to cask is stopped
+aslack to the buoy rope from the shell up to the cask to
+which it is securely seized, to prevent any strain upon
+that part which enters the cask. The return wire is
+stopped in like manner down the buoy ropes to the shell,
+and then along the span to the next shell. At 4 the two
+cords are rapped together, loaded with trace chains a
+fathom apart and carried ashore to the galvanic battery.
+For batteries we have 21 Wollastons, each trough containing
+18 pairs of plates, zinc and wire, 10 x 12 inches.
+The first range is called 1: the second 2: the third 3, and
+the wires are so labelled. Thus all of each range are exploded
+at once.</p>
+
+<p>Besides these there are two ranges of two tanks each,
+planted opposite the battery at Chaffin's Bluff. When
+they were planted it was not known that a battery was
+to be erected below. These four tanks contain about
+6,000 pounds of powder. The great freshets of last
+month carried away the wires that were to operate the
+first pair. Lieut. Davidson, who, with the "Teaser" and
+her crew, has assisted me with the most hearty good
+will, has dragged for the tanks, but without success, they
+rest on the bottom. Could they be found it was my
+intention to raise the four, examine them and if in good
+condition, place them lower down.</p>
+
+<p>Lieut. Wm. L. Maury, assisted by Acting Master
+W. F. Carter, and R. Rollins, was charged with the duty
+of proving the tanks and packing them in casks. There
+are eleven others, each containing 70 pounds of powder.
+When tested in the barrels and found ready for use, they
+will be held in reserve in case of accident to those already
+down. A larger number was not prepared for
+want of powder. There are a quantity of admirably
+insulated wires, a number of shells for anchor or torpedoes
+and a sufficient quantity of chains for the wires
+remaining. They will be put in the navy store for safe
+keeping.</p>
+
+<p>The galvanic batteries, viz.: 21 Wollaston and one
+Cruickshank (the latter loaned by Dr. Maupin of the
+University of Virginia), with spare acids are at Chaffin's
+Bluff in charge of Acting Master Cheeney. He has also
+in pigs a sufficient quantity mixed to work the batteries,
+and ready to be poured in for use.</p>
+
+<p>It is proper that I should mention to the department,
+in terms of commendation the ready and valuable assistance
+afforded by Dr. Morris, president of the Telegraph
+Company, and his assistants, especially Mr. Goldwell.</p>
+
+<p>My duties in connection with those batteries being
+thus closed, I have the honor to await your further
+orders.</p>
+
+<p>Respectfully, etc.,</p>
+
+<p class="ralign5">M. F. MAURY,<br />
+Commander C. S. Navy.<br />
+Hon. S. R. Mallory,<br />
+Secretary of the Navy, Present.</p>
+</div>
+
+<p>Shortly after, Captain Maury was ordered to London
+on secret service for the Navy Department, and that he
+might avail himself of laboratories and workshops for
+experiment and improvement of his new science, in which
+he was now regarded as supreme authority. He was
+to report progress and improvement in this new means
+of making successful war from time to time to the Navy
+Department, which was constantly done during the next
+two years, and thus the result of his labours and inventions
+communicated to the officers in charge of the torpedo
+stations now established along our Atlantic Coast.
+His devices and inventions, which have not since been
+surpassed and some of which are still in use, had reference
+chiefly to exploding the torpedo; to determining
+with certainty from a distance the moment when a ship
+should enter within explosive range, and at all times
+to test its condition and to verify its location.</p>
+
+<p>Lieut. Hunter Davidson, his valued assistant, succeeded
+him in charge of the James River batteries,
+and in time extended the mines some distance below.
+During the two years when he was in charge he
+planted many electrical torpedoes in the channel of the
+river, to be fired from concealed stations on shore.
+Some of these contained 1,800 pounds of powder.</p>
+
+<p>In August, 1862, the Federal steamer "Commodore
+Barney" was badly disabled by one of these, and in
+1864 the "Comm. Jones" was totally destroyed, with
+nearly all on board, the first fruits of Maury's electrical
+torpedo defense. The first vessel destroyed by a submarine
+torpedo was the gunboat&mdash;ironclad&mdash;"Cairo," in
+the Yazoo River. The torpedo was a demijohn of powder
+enclosed in a box sunk in the river and fired by a
+string from the shore. Lieut. Beverley Kennon claimed
+the credit for this but Masters McDaniel and Ewing did
+the actual work.</p>
+
+<p>Early in 1864 Davidson, in a steam launch, specially
+constructed for him, called "The Torpedo," having made
+120 mile run down James River, all within the enemies'
+lines, exploded a torpedo against the flagship "Minnesota,"
+at anchor off Newport News. The river swarmed
+with the enemy's vessels, and the guard boat was lying
+by the "Minnesota," but her captain had allowed his
+steam to go down. Davidson hit the great ship full and
+fair, causing great consternation on board, but the torpedo
+charge was only fifty-three pounds of powder and
+it failed to break in her sides, although considerable
+damage was done. Davidson suffered no injury and returned
+to Richmond without incident.</p>
+
+<p>On August 9, 1864, there was a great explosion in
+Grant's lines at City Point, on the James, caused by a
+torpedo with a clock attached which caused it to explode
+at a given hour. With daring unexcelled John Maxwell
+and R. K. Dillard, of the torpedo corps, made their way
+into the lines, carrying the machine neatly boxed with
+them, which Maxwell handed aboard one of the boats
+lying at the wharf, saying that the captain had directed
+him to do so. In half an hour there was a terrible explosion,
+killing and wounding fifty men and destroying
+much property and many stores besides, injuring many
+nearby vessels, which brave John Maxwell quietly witnessed
+seated upon a log upon a hillside close by.</p>
+
+<p>Lieut. Beverly Kennon was also most active in this
+system of defense and personally planted many torpedoes
+in the Potomac, Rappahannock and the James.
+He and Lieut. J. Pembroke Jones succeeded Lieutenant
+Davidson in charge of the torpedo defense of the James.
+A defense in itself equivalent to a well appointed fleet
+or army, since, as is well known, it served to keep the
+enemy out of Richmond till the close of the war, and
+converted them into earnest advocates of its use.</p>
+
+<p>General Raines, chief of the Army Torpedo Bureau,
+had early adopted as the best form of torpedo, the beer
+barrel filled with powder and fitted with a percussion
+primer at each end. They were set adrift in pairs down
+the river by the hundred to be carried by current and
+tide against the enemy's ships below. Though many
+necessarily failed and drifted out to sea, if but a single
+one in a great number succeeded the Confederacy was
+well repaid. At times as many as a hundred a day were
+caught by the enemy's netting set out for that purpose
+in the James River alone.</p>
+
+<p>Captain Francis D. Lee, of General Beauregard's
+staff, recommended the spar torpedo, which was very
+successfully used, especially in the waters around Charleston.
+It was a case to contain seventy pounds of powder
+set on the end of a twenty foot spar and rigged on
+the bow of a boat. It was exploded by contact on the
+side of the vessel attacked.</p>
+
+<p>In 1862 Dr. St. Julien Ravenal, Mr. Theodore Stoney
+and other gentlemen of Charleston, after consultation
+with Captain Maury, designed and had constructed a
+semi-submarine torpedo boat, the first of its type. It
+was called the "David," for it was intended to attack
+the Goliath of the federal blockading fleet. After its
+remarkable experience and success, its name was used
+as the name for its type and the Confederacy had many
+"Davids" on the stock when the war ended. It was
+cigar shaped, twenty feet long, five in diameter at the
+center. The boiler was forward, the miniature engine
+aft, and between them a cuddy hole for captain and
+crew. The torpedo was carried on a spar protruding
+fifteen feet from the bow, and could be raised or lowered
+by a line passing back into the cuddy hole. It was of
+copper containing 100 pounds of rifle powder and provided
+with four sensitive tubes of lead, containing explosive
+mixture. A two bladed propellor drove the craft
+at a six or seven knot rate. When ready for action the
+boat was so well submerged that nothing was visible
+save the stunt smoke-stack, the hatch combings and the
+stanchion, upon which the torpedo line was brought aft.
+The torpedo was submerged about six feet. Lieutenant
+W. T. Glassel, of the Confederate Navy of Virginia, one
+of the bravest of the brave, volunteered to take charge
+of her. He says Assistant Engineer J. H. Toombs volunteered
+his services, Major Frank Lee gave me his
+zealous service in fitting a torpedo. James Stuart, or
+Sullivan, volunteered to go as fireman, and the services
+of J. W. Cannon as pilot were secured. I had an armament
+on deck of four double-barrel shotguns, and as
+many navy revolvers; also four cork life preservers had
+been thrown on board to make us feel safe. On the fifth
+of October, 1863, they left Charleston a little after dark,
+bound for the federal fleet outside, and especially for
+the "New Ironsides," the most powerful ship afloat. He
+thus graphically describes what occurred: "We passed
+Fort Sumter and beyond the line of picket boats without
+being discovered. Silently steaming along just inside
+the bar, I had a good opportunity to reconnoiter the
+whole fleet at anchor between me and the camp fires on
+Morris Island.</p>
+
+<p>"The admiral's ship, 'New Ironsides,' lay in the midst
+of the fleet, her starboard side presented to my view, I
+determined to pay her the highest compliment. I had
+been informed through prisoners lately captured from
+the fleet, that they were expecting an attack from torpedo
+boats and were prepared for it. I could hardly,
+therefore, expect to accomplish my object without encountering
+some danger from riflemen, and, perhaps, a
+discharge of grape or canister from the howitzers. My
+guns were loaded with buckshots. I knew that if the
+officer of the deck could be disabled to begin with, it
+would cause them some confusion, and increase our
+chance of escape, so I determined that if the occasion
+offered I would commence by firing the first shot. Accordingly,
+having on a full head of steam, I took charge
+of the helm, it being so arranged that I could sit on the
+deck, and work the wheel with my feet. Then directing
+the engineer and fireman to keep below, and give me all
+the speed possible, I gave a double-barrel gun to the
+pilot, with instructions not to fire until I should do so,
+and steered directly for the monitor. I intended to strike
+her just under the gangway, but the tide still running
+out carried us to a point nearer the quarter. Thus we
+rapidly approached the enemy. When within 300 yards
+of her a sentinel hailed us. Boat ahoy! repeating the
+hail several times very rapidly. We were coming toward
+them with all speed and I made no answer but cocked
+both barrels of my gun. The officer of the deck next
+made his appearance and loudly demanded, 'What boat is
+that.' Being now within forty yards of the ship and with
+plenty of head way to carry me on, I thought it about
+time the fight should commence and fired my gun. The
+officer of the deck fell back mortally wounded (poor
+fellow), and I ordered the engine stopped. The next
+moment the torpedo struck the vessel and exploded.
+What amount of direct damage the enemy received I
+will not attempt to say. My little boat plunged violently
+and a large body of water, which had been thrown up,
+descended upon her deck, and down the smoke-stack and
+hatchway.</p>
+
+<p>"I immediately gave orders to reverse the engine and
+back off. Mr. Toombs informed me then that the fires
+were put out, and something had been jammed in the
+machinery, so that it would not move. What could be
+done in this situation? In the meantime the enemy, recovering
+from the shock, beat to quarters and general
+alarm spread through the fleet. I told my men I thought
+our only chance of escape was by swimming and I think
+I told Mr. Toombs to cut the water pipes and let the
+boat sink. Then taking one of the cork floats I got into
+the water and swam off as fast as I could.</p>
+
+<p>"The enemy in no amiable mood poured down upon
+the bubbling water a hailstorm of rifle and pistol
+shots from the deck of the 'Ironsides,' and from the nearest
+monitor. Sometimes they struck very close to my
+head, but swimming for life I soon disappeared from
+sight and found myself alone in the water. I hoped that
+with the assistance of the flood tide I might be able to
+reach Fort Sumter, but a north wind was against me, and
+after I had been in the water more than an hour I became
+numb with cold and was nearly exhausted. Just
+then the boat of a transport schooner picked me up and
+found to their surprise that they had captured a 'rebel.'
+I was handed over next morning to the mercy of Admiral
+Dahlgren, who ordered me to be put in irons, and
+if obstreperous, in double irons. When on the flagship
+I learned that my fireman had clung to her rudder chains
+and been taken on board.</p>
+
+<p>"Engineer Toombs started to swim towards the
+'Monitor,' with the intention of catching her chains, but
+changed his mind when he saw that the 'David' was
+afloat, and had drifted away from the frigate. Swimming
+to her he found Pilot Cannon, who not being able
+to swim, when the fires were extinguished jumped overboard
+and clung to the unexposed side of the 'David.'
+After drifting about a quarter of a mile he got back on
+board and seeing something in the water he hailed and
+heard, to his surprise, a reply from Toombs, who soon got
+on board. Finding the boat uninjured, though a bull's
+eye canteen afforded a mark to the Federal cannoneer,
+they fixed the engine, started up the fires, got up steam
+and started back to Charleston, reaching the Atlantic
+dock about midnight."</p>
+
+<p>As the result of this most daring feat it was found
+that the torpedo had exploded under three feet of water
+and against four and one-half inches of armour, and
+twenty-seven inches of wood backing. The ponderous
+ship was shaken from stem to stern, and was docked for
+repairs until the attack on Fort Fisher, while the
+"David" and her crew were uninjured. Captain Rowan
+reported that the ship was very seriously injured and
+ought to be sent home for repairs, and Admiral Dahlgren
+informed the Secretary of the Navy that, "Among the
+many inventions with which I have been familiar, I
+have seen none that acted so perfectly at first trial. The
+secrecy, rapidity of movement, control of direction and
+precise explosion, indicate, I think, the introduction of
+the torpedo element as a means of certain warfare. It
+can be ignored no longer. If sixty pounds of powder
+why not 600," and the Secretary of the Confederate Navy
+reported: "On the evening of the 5th of October Lieutenant
+W. T. Glassell, in charge of the torpedo boat,
+"David," with Assistant Engineer Tomb, Pilot Walker
+Cannon, and Seaman James Sullivan, left Charleston to
+attempt the destruction of the enemy's ship, 'New Ironsides.'
+Passing undiscovered through the enemy's fleet,
+he was hailed by the watch as he approached the ship
+and answering the hail with a shot, he dashed his boat
+against her and exploded the torpedo under her bilge.
+The fires were extinguished, and the boat was nearly
+swamped by the concussion and the descending water,
+and Lieutenant Glassell and Sullivan, supposing her to
+be lost swam off and were picked up by the enemy. Engineer
+Tomb and Pilot Cannon succeeded in reaching
+Charleston with the boat.</p>
+
+<p>"Although Lieutenant Glassell failed to accomplish
+his chief object, it is believed that he inflicted serious
+injury upon the 'Ironsides,' while his unsurpassed daring
+must be productive of an important moral influence, as
+well upon the enemy as upon our own naval force."</p>
+
+<p>The annals of naval warfare record few enterprises
+which exhibit more strikingly than this of Lieutenant
+Glassell the highest qualities of a sea officer.</p>
+
+<p>At this time there were sixty officers and men on torpedo
+duty at Charleston alone.</p>
+
+<p>The most remarkable career in all torpedo history
+was that of a little boat built in Mobile Bay, and operated
+upon the fleet off Charleston. She was the pioneer of
+all submarine torpedo boats, as she was the first to
+achieve success.</p>
+
+<p>She was built in 1863-4 at Mobile by Mr. Horace L.
+Hundley, at his own expense. She was made of boiler
+plate, was shaped like a fish twenty-four feet long, five
+feet deep, three feet wide; she had fins on each side,
+raised or depressed from the interior; her motive power
+was a small propeller worked by manual power of her
+crew seated on each side of the shaft; she was provided
+with tanks which could be filled or empitied of water
+to increase or dimish her displacement; but had no provision
+for air storage. The captain stood in a circular
+hatchway well forward and steered the boat, and regulated
+the depth at which she should proceed. When she
+dived all was made tight until she rose again. She had
+no ventilation. She was designed to tow a torpedo
+astern, dive under the vessel attacked, dragging the torpedo
+after; she would then rise to the surface on the
+other side, when the torpedo would explode by contact
+with the bottom of the vessel, and the torpedo boat
+make off in the darkness and confusion. General Maury
+states that on her trial trip, which he saw, she towed a
+floating torpedo, dived under a ship, dragging the torpedo,
+which fairly exploded under the ship's bottom,
+and blew the fragments one hundred feet into the air; and
+that not being able to use her in Mobile, he sent her, and
+her crew to Charleston. It is said that during another
+trial in Mobile she sank and all on board perished before
+she was raised.</p>
+
+<p>Lieutenant Payne, of the Navy, volunteers to take her
+out, and secured a volunteer crew of sailors. She was
+named the "H. L. Hundley." While tied to the wharf
+at Fort Johnston, whence it was to start at night to
+make the attack, a steamer passing close by, filled and
+sank it, drowning all hands save Payne, who was at the
+time standing in one of the manholes. She was promptly
+raised, but was again sunk, this time at Fort Sumter
+wharf, when six men were drowned, Payne and two
+others escaping. When she was brought to the surface
+again. McKinley and a trained crew came from Mobile,
+bringing with him Lieutenant Dixon, of the Twenty-first
+Alabama Infantry, to fight the boat. He made repeated
+descents in the harbour, diving under the receiving ship
+again and again successfully. But one day, when Dixon
+was absent from the city, Mr. Hundley, wishing to
+handle the boat himself, unfortunately made the attempt;
+it was readily submerged but did not rise again
+and all on board perished, from asphyxiation. When the
+boat was discovered, raised and opened the spectacle was
+indescribably ghastly, the unfortunate men were contorted
+into all kinds of attitudes horrible to see; some
+clutching candles, evidently endeavouring to force open
+the manholes; others lying on the bottom tightly grappled
+together; and the blackened faces of all presented
+the expression of their agony and despair.</p>
+
+<p>The "Hundley" had thus cost the lives of thirty-three
+brave men, but nevertheless, there were still found volunteers
+to risk theirs for their country&mdash;and Lieutenant
+Dixon found no difficulty in enlisting eight more heroes
+to attack the Federal steam sloop of war, "Housatonic,"
+a powerful new vessel of eleven guns, lying on the north
+channel, opposite Beach Inlet, off Charleston. General
+Beauregard had refused to let it be used again, but
+Lieutenant Dixon, having undertaken to use the boat
+with a spar torpedo in the same manner as the "David,"
+consent was given and preparations for the attack were
+again made.</p>
+
+<p>Dixon was a Kentuckian and was moved by the highest
+principle and patriotism in making this venture. He
+had taken an active part in the construction of the vessel,
+and had caused other men to perish in her by dangers
+he had not shared, now bravely demanded this opportunity.
+His crew were Arnold Becker, C. Simpkins,
+James A. Wick, T. Collins and &mdash;&mdash; Ridgeway, of the
+Navy, and Corporal J. F. Carlson, of the artillery. All
+knew the fearful risk they ran&mdash;and all were willing to
+sacrifice their lives for their country, counting the cost
+as nothing if thereby they could procure the destruction
+of the "Housatonic."</p>
+
+<p>Everything being ready at twilight on the 17th of
+February, 1864, these devoted heroes took their places
+in the boat at Sullivan's Island, and set off upon their
+perilous adventure. This time she got away successfully,
+but that is the last that we hear of her save the official
+report from the enemy, that about 9 o'clock an object
+like a plank was seen approaching, which in a moment
+more struck the ship with a great explosion, blowing up
+the after part of the ship, causing her to sink immediately
+to the bottom, drowning five men and injuring
+many more.</p>
+
+<p>The "Hundley" was never heard of again till several
+years after the war, divers sent down to wreck the
+"Housatonic," found her little antagonist lying on the
+bottom near by.</p>
+
+<p>Admiral Dahlgren reported to the Secretary of the
+U. S. Navy, as follows:</p>
+
+<p>Sir, I much regret to inform the Department that
+the U. S. S. "Housatonic," on the blockade off Charleston,
+S. C., was torpedoed by a rebel "David" and sunk
+on the night of February 17th, about 9 o'clock.</p>
+
+<p>From the time the "David" was seen until the vessel
+was on the bottom, a very brief period must have elapsed,
+as far as the executive officer can judge, it did not exceed
+five or seven minutes.</p>
+
+<p>The officer of the deck perceived a moving object on
+the water quite near and ordered the chain to be slipped:
+the captain and the executive officer went on deck, saw
+the object, and each fired at it with a small arm. In an
+instant the ship was struck on the starboard side between
+the main and mizzen masts. Those on deck near were
+stunned, the vessel began to sink, and went down almost
+immediately.</p>
+
+<p>The Department will readily perceive the consequences
+likely to result from this event: the whole line
+of blockade will be infested with these cheap, convenient
+and formidable defenses, and we must guard every
+point. The measures of prevention are not so obvious.
+I am inclined to the belief that in addition the various
+devices for keeping the torpedoes from the vessels, an
+effectual prevention may be found in the use of similar
+contrivances. * * *</p>
+
+<p>I have attached more importance to the use of torpedoes
+than others have done, and believe them to constitute
+the most formidable of the difficulties in the way
+to Charleston. Their effect on the "Ironsides" in October,
+and now on the "Housatonic," sustains me in the
+idea. And thereupon he makes application to be furnished
+a number of torpedo boats made upon the model
+of the "David," a sketch of which is submitted, and
+also a quantity of floating torpedoes, and suggests that
+as he has information that the Confederates have a number
+of "Davids" completed and in an advanced state of
+construction, the Department would do well to offer a
+large reward of prize money for the capture or destruction
+of any of them, say $20,000 or $30,000 for each, adding,
+"they are worth more than that to us."</p>
+
+<p>About the same time Admiral Farragut, who had
+little faith in torpedoes at first, and who like other naval
+officers had denounced their use by the Confederates,
+and ordered that no quarter should be shown those captured
+operating them, also applied to be furnished them,
+saying, "Torpedoes are not so very agreeable when used
+on both sides, therefore, I have reluctantly brought
+myself to it. I have always deemed it unworthy
+of a chivalrous nation, but it does not do to give
+your enemy such a decided superiority over." And the
+Government of the United States, who had savagely
+denounced the Confederates for using them, now invited
+plans from inventors and mechanics for their construction,
+and operation, and soon supplied them abundantly
+to Army and Navy&mdash;adopting generally the Confederates
+as the best.</p>
+
+<p>In August, 1864, the Federal fleet advanced upon
+Fort Morgan at the entrance of Mobile Bay, the line
+being led by "Tecumseh," the newest and most powerful
+of the enemy's ironclads, which was completely destroyed
+by a torpedo planted under the direction of General
+Raines, Chief of the Confederate Army Torpedo Bureau.
+She sunk in a moment, carrying down with her her entire
+crew of one hundred and forty souls, save about
+fifteen or twenty who escaped by swimming to Fort
+Morgan.</p>
+
+<p>This was the greatest achievement of a single torpedo
+during our war and served to stimulate the Confederate
+authorities to renewed vigour. Thenceforward, the Bay
+of Mobile and adjacent waters became the chief scenes
+of torpedo operation. Genl. Maury stated that he had
+caused to be placed 180 in her channel and waterways,
+that they held the powerful fleet of Admiral Farragut for
+ten months at bay, and destroyed fully a dozen United
+States vessels, of which six were gunboats and four were
+monitors. Regular torpedo stations were established
+in Richmond, Wilmington, Charleston, Savannah and
+Mobile, at which sixty naval officers and men were on
+duty, preparing these new engines of war. The channel-ways,
+rivers and harbours were protected by them from
+Virginia to Texas. Sometimes a hundred were taken out
+of James River in a single day, and when the Southern
+seaports fell hundreds of torpedoes were found floating
+in their waters ready to explode upon the first contact.
+At first the older Confederate officers who regarded them
+with disfavour, as Captain Wm. H. Parker says he did,
+were now "torpedo mad." "Commodore Tucker and I,"
+he said, "had torpedo on the brain," and the destruction
+of the enemy's vessels increased so rapidly that in the
+last ten months of the war forty or fifty were blown up,
+and in the last three weeks ten or more were destroyed.
+Its possibilities became better and better appreciated
+every day. Think of the destruction this machine affected,
+and bear in mind its use came to be fairly understood
+only during the last part of the war. During that
+period, when but few Federal vessels were lost and
+fewer still severely damaged by the most powerful guns
+in use, we find this long line of disasters from the Confederate
+use of this new and in the beginning despised
+comer into the arena of naval warfare. Our successes
+have made the torpedo a name spoken of with loathing
+and contempt by the self-sufficient Yankee, a recognized
+factor in modern naval warfare, and now we see on all
+sides the greatest activity and genius in improving it.</p>
+
+<p>The wonderful inventive genius and energetic action
+of the Confederate officers, and engineers astounded the
+world by their achievements in the unknown and untried
+science in naval warfare. They not only made it most
+effective for sea coast and harbour defence, but terrible
+as an agency of attack on hostile ships of war. Not only
+that, but they brought the system to such a high state of
+perfection that little or no advance or improvement has
+since been made in it, and within a short period of the
+inception of the design a system was formed so perfect
+and complete as that the advance upon the water by the
+enemy was materially checked. They startled naval constructors
+and officers in the civilized world by the
+rapidity, audacity and novelty of their original methods,
+and will be known through all ages for their wonderful
+achievements. Maury, Buchanan, Brook, Jones and their
+assistants are the central figures around which revolve to
+the present day the changes from the old to the new in
+naval warfare.</p>
+
+<p>Meantime Captain Maury was most diligently employed
+in London, under the order of the Navy Department
+in developing and improving his system, afforded
+by the workshops and laboratories there for experiment
+and construction. Here he continued during 1863 and
+1864, pursuing these researches, perfecting many valuable
+inventions, and instruments with signal success. He
+reported to the Secretary of the Navy at home, so far as
+it was safe to do so, by whom results were passed on to
+officers in charge for their instruction and guidance and
+shipping continuously to the department supplies of insulated
+wire, exploders, and other inventions and devices
+whose object was to increase the destructiveness of the
+torpedo and to test it continually without removing it.
+In the spring of 1865, he sailed for Galveston with the
+most powerful and perfect equipment of electric torpedo
+material ever assembled. Great results were confidently
+expected from this armament, but before he reached
+Havana news arrived of General Lee's surrender.</p>
+
+<p>But his experience and study and his scientific renown
+had now made him the leading authority in this new
+weapon of war mainly perfected by him. He was also
+now relieved from the seal of secrecy hitherto imposed
+upon him, so that when a year afterwards he returned to
+Europe he felt himself at liberty to impart to the
+sovereign there the secret of his discoveries concerning
+his new made science. Most of the European powers
+sent representatives to his school of instruction&mdash;and all
+of them have built upon his beginnings, the most powerful
+branch of their naval armaments.</p>
+
+<p>To France he first imparted his secret and the Emperor
+witnessed the experiment and himself closed the
+circuit and exploded a torpedo placed in the Seine, near
+St. Cloud, to the perfect satisfaction of all. Russia,
+Sweden, Holland, England and others soon also received
+his instructions and they, too, have since built up a new
+method of defence second to none.</p>
+
+<p>My own experiments, Captain Maury says, show
+that the electrical torpedo, or mine has not hitherto been
+properly appreciated as a means of defence in war.
+It is as effective for the defence as ironclads and
+rifled guns are for the attack. Indeed, such is the
+progress made in what may be called this new Department
+of Military Engineering that I feel justified in the
+opinion that hereafter in all plans for coast, harbour and
+river defences and in all works for the protection of
+cities and places whether against attacks by armies on
+land or ships afloat, the electrical torpedo is to play an
+important part. It will not only modify and strengthen
+existing plans, but greatly reduce the expense of future
+systems.</p>
+
+<p>These experiments have resulted in some important
+improvements and contrivances, not to say inventions
+and discoveries which as yet have been made known only
+to the Confederate Government. They are chiefly as
+follows:</p>
+
+<p>First. A plan for determining by cross bearing
+when the enemy is in the field of destruction, and for
+"making connections" among the torpedo wires in a certain
+way and by which (the concurrence of two operators)
+becomes necessary for the explosion of any one or
+more torpedoes. This plan requires each operator to be
+so placed, or stationed that a line drawn straight from
+them to the place of the torpedoes may intersect as nearly
+as practicable at right angles, and it requires the connections
+to be such that each operator may put his station
+in or out of circuit at will. When the torpedoes are
+laid, a range from each station is established for every
+torpedo or group of torpedoes. When either operator
+observes an enemy in range with any torpedo he closes
+his circuit for that torpedo. If the enemy before getting
+out of this range should enter the range for any torpedo
+from the other station the operator then closes his circuit,
+and discharges the igniting spark.</p>
+
+<p>Consequently if the range belongs to the same torpedo
+its explosion takes place. But if not there will be
+no explosion; hence, here is an artifice by which explosion
+becomes impossible when the enemy is not within
+the field of destruction, and sure when she is.</p>
+
+<p>Second. The "Electrical Gauge," a contrivance of my
+own, by means of which one of the tests which the igniting
+fuse has to undergo before it is accepted, is applied. By
+means of it the operators can telegraph through the fuse
+to each other without risk to the torpedoes, and by which
+the torpedoes, may without detriment to their explosibility
+be tested daily, or as often as required. And thus
+the operator can at all times make sure that all is right.</p>
+
+<p>Third. A plan for planting torpedoes where the
+water is too deep for them to lie on the bottom and explode
+with effect, by which they will not interfere with
+the navigation of the channel, and by which when the
+enemy makes his appearance they may, by the touch of
+a key be brought instantly into the required position and
+at the proper depth.</p>
+
+<p>These contrivances are all very simple; they are
+readily understood from verbal instruction, they require
+neither models or drawings, and enable the operator
+chiefly to use the self same wire for testing his torpedoes
+daily after they are planted, and then to explode them
+at will.</p>
+
+<p>Though these torpedoes, owing to the lack in the
+Confederacy of the proper materials and appliances for
+their construction and use, were make-shifts, yet so effective
+had their use become, especially during the last year
+of the war, that the Secretary of the American Navy, in
+his annual report of December, 1865, to the President
+of the United States, thus testifies to their efficiency:
+"Torpedoes always formidable in harbours and internal
+waters, have been more destructive to our naval vessels
+than all other means combined."</p>
+
+<p>Since 1862, finding myself in reach of the facilities
+afforded in England, I have made the study of Electrical
+torpedoes a specialty, and the results are such, to say
+the least, as to show that it is capable of doing quite as
+much for the defence as ironclads and rifled guns are
+likely to do for the attack.</p>
+
+<p>These results consist in improvements and discoveries
+which enable the adept in that new department of military
+engineering to explode his torpedoes whether buried
+on land or submerged in the water, singly or in groups,
+instanteously and at any distance to transmit through
+them without the risk of explosion, orders and commands,
+and as readily as through the ordinary line of telegraph.
+To determine with unerring certainty when the enemy is
+in the field of destruction of this or that torpedo. To
+render its explosion impossible, unless he be in such field,
+even though the igniting spark should be discharged;
+and so to set an electrical current to watch it, as to make
+the injuring of it without his knowledge impossible, and
+the removal of it by an enemy, if not impossible, extremely
+difficult and dangerous.</p>
+
+<p>Electrical torpedoes are also available for the defense
+of mountain passes, roadways and fortified positions on
+land.</p>
+
+<p>I am not aware that electricity was used at all in the
+Confederate war for springing mines on land. Shell cast
+for this purpose should be used but in an emergency, tin
+canisters, or other perfectly water-tight cases, will answer.
+These shells should be one-fourth of an inch thick
+to one inch, according to size and probable handling in
+transportation. They should be spherical only instead of
+a hole for the fuse as in a hollow shot they should have
+a neck like a bottle, with a cap to screw over, not in the
+neck. The case should be charged through the neck, and
+the wires let in through two holes counter sunk diametrically
+opposite, the counter sinking being for the purpose
+of receiving pitch or other resinous matter, to keep
+the water out. The fuse being adjusted to the wires
+should be held in place by a string through the neck while
+the wires drawn out taut and sealed within and without.
+Having proved the fuse, first fill and then drive in the
+peg. Then fill the space between it and the screw-cap
+with red lead and screw down so as to make water-tight.
+Now secure the tails of the wires so that they will not
+be chafed or bruised, and the mine is ready for transportation.</p>
+
+<p>They are general to be used in stone fougasses, the
+wire being buried at convenient depths and all marks of
+fougasses and trenches removed as completely as possible.
+Any number not exceeding twenty-five or thirty
+may be arranged in a single circuit for the Ebonite; but
+if the magnetic exploder of Wheatstone be preferred, and
+the ground be perfectly dry, hundreds may be planted in
+a latter circuit.</p>
+
+<p>The operator may be at any distance from these
+primas when he explodes them, provided only he has
+established some mark or point which on being seen
+by the enemy should serve as a signal. The area of destruction
+of fougasses properly constructed with a charge
+of twenty or thirty pounds of powder may be assumed to
+be that of a circle seventy-five or eighty yards in diameter.
+Twenty mines would therefore serve for a mile.
+Several miles may be planted in a night and the assailants
+may be enticed, or invited out in the morning.
+Passes before an invading army may be mined in advance
+and thus if he cannot be destroyed, his progress may be
+so retarded by dress mines or sham mines as almost
+literally to dig his way.</p>
+
+<p>The power to telegraph through these torpedoes is
+of little consequence, in as much as there need be but
+one station and one operator. Using the testing fuse
+manufactured by Abel and a weak voltaic current, the
+operator can at any time satisfy himself as to continuity.
+Thus "bridge" and "gulfs" or "breaks" are not required
+for the land as they are in sea-mining. Ebonite has the
+further advantage on land that it takes but a single wire.</p>
+
+<p>Forts may be protected against assault and your own
+rifle pits from occupation by an enemy simply by a proper
+distribution of these new engines of war. They may be
+planted line within line and one row above another, and
+so arranged that volcanoes can be sprung at will under
+the feet of assaulting columns. And these improvements
+and discoveries enable the engineer at small cost, and
+short notice effectually to defend any roadstead, or block
+any river, harbour or pass against the land and naval
+forces of an enemy without in the least interfering with
+the free use of the same by friendly powers.</p>
+
+<p>To this admirable state of efficiency was the new and
+terrible science of war perfected, chiefly by the Confederate
+Navy, and mainly through the instrumentality of
+its faithful, and devoted officer Captain Matthew F.
+Maury, and his brave and daring young assistants, Minor,
+Davidson, Kennon, Dixon, Glassel, and many others, and
+those crews of the "Hundley," who moved by the lofty
+faith that with them died, volunteered for enterprise of
+extremest peril in the defense of Charleston Harbour, in
+which they all perished, in this desperate service, of whom
+the names of but the following are known: Horace L.
+Hundley, George E. Dixon, Robert Brookland, Jos. Patterson,
+Thomas W. Park, Chas. McHugh, Henry Beard,
+John Marshall, C. L. Sprague, C. F. Carlson, Arnold
+Beeker, Jos. A. Wicks, C. Simpkins, F. Collins, Ridgway,
+Miller, whose monument erected by the ladies of Charleston,
+stands upon the battery there in perpetual memory
+and honour.</p>

+1.F.
+
+1.F.1. Project Gutenberg volunteers and employees expend considerable
+effort to identify, do copyright research on, transcribe and proofread
+public domain works in creating the Project Gutenberg-tm
+collection. Despite these efforts, Project Gutenberg-tm electronic
+works, and the medium on which they may be stored, may contain
+"Defects," such as, but not limited to, incomplete, inaccurate or
+corrupt data, transcription errors, a copyright or other intellectual
+property infringement, a defective or damaged disk or other medium, a
+computer virus, or computer codes that damage or cannot be read by
+your equipment.

+1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
+of Replacement or Refund" described in paragraph 1.F.3, the Project
+Gutenberg Literary Archive Foundation, the owner of the Project
+Gutenberg-tm trademark, and any other party distributing a Project
+Gutenberg-tm electronic work under this agreement, disclaim all

+Project Gutenberg-tm work, and (c) any Defect you cause.
+
+
+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at https://www.pglaf.org.
+
+
+Section 3. Information about the Project Gutenberg Literary Archive
+Foundation
+
+The Project Gutenberg Literary Archive Foundation is a non profit
+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal
+Revenue Service. The Foundation's EIN or federal tax identification
+number is 64-6221541. Its 501(c)(3) letter is posted at
+https://pglaf.org/fundraising. Contributions to the Project Gutenberg
+Literary Archive Foundation are tax deductible to the full extent
+permitted by U.S. federal laws and your state's laws.
+
+The Foundation's principal office is located at 4557 Melan Dr. S.
+Fairbanks, AK, 99712., but its volunteers and employees are scattered
+throughout numerous locations. Its business office is located at
+809 North 1500 West, Salt Lake City, UT 84116, (801) 596-1887, email

+
+
+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit https://pglaf.org
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including including checks, online payments and credit card
+donations. To donate, please visit: https://pglaf.org/donate
+
+
+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart was the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+
+Most people start at our Web site which has the main PG search facility:
+
+ https://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.
