Part 1 — CHAPTER IV. (continued 2)

332. The times of flight and length of fuze for all projectiles, so far as ascertained at the Experimental Battery at Washington, are given in the Table of Ranges, Appendix B.

333. The best effect of a percussion-fuze is obtained by firing into a mass of timber. They frequently fail if fired into a bank of soft earth, sand, or other material which does not offer a sufficiently sudden resistance; also, if fired at high angles of elevation, owing to the fact that the rifle-shells do not generally strike point foremost.

334. Time-fuzes are also very unreliable in rifle-guns; expanding projectiles cut off the flame from the fuze.

With the Parrott shell, however, the Navy time-fuze is the most certain of ignition and regular in its time of burning. The safety-plug should be removed when the Navy time-fuse is used in rifled cannon, as recent experiments show that it is a probable cause of premature explosions of shells.

In testing the Navy time-fuse by the watch, or michronometer, the safety-plug must be removed: otherwise the fuze will burn longer than the time for which it is marked.

BOARDERS.

335. It is not supposed that any directions can be framed which will entirely provide for all the various circumstances which may require attention when about to board an enemy, or to repel a similar assault made by an enemy upon our vessels.

The following general suggestions are, however, presented for the consideration of Captains, in order that some degree of uniformity may be preserved when other more important considerations do not prevent it.

336. Upon the signal for Boarders, the divisions called should form on the gangway of the side which is not engaged, properly armed, and remain there until ordered elsewhere, provided there be time to make this disposition of them. In all movements from one part of the ship to another, cutlasses should be sheathed and pistols in the frogs. The men of each division should be united as much as possible under their own officer. Bayonets not fixed until ordered.

"PREPARE TO BOARD!"

(FROM ANY SPECIFIED PART OF THE SHIP.)

337. The Boarders should repair to the place directed, taking care to keep themselves down so as not to be seen by the enemy, and form close to the bulwarks, until the order is given to—

"BOARD THE ENEMY!"

338. The Boarders should then gain the enemy's deck as quickly as possible, keeping near enough to each other for mutual support, and to act in concert against the opposing force, using every possible exertion to clear the enemy's decks by disabling or driving the men below.

In case the intention of boarding should be discovered by the enemy, and he collects his men to repel the attack, the marines and small-arm men should take positions where they can best fire upon the men thus collected; and, if possible, the spar-deck guns loaded with grape, and howitzers loaded with canister, should be used for the same purpose before the Boarders are ordered to make the attack.

So long as the contest is continued after boarding, the fire should be kept up against the enemy from all the guns with as much vigor as the number of men remaining at them will allow.

The guns should then be much depressed, in order that there may be little or no danger to our own men. Much positive injury may be inflicted on the enemy in this way, besides the advantages of dividing his attention at such an important moment.

If it should be necessary to repel Boarders from the enemy, the Boarders and Pikemen must be called, and at the order—

"PREPARE TO REPEL BOARDERS!"

(AT ANY SPECIFIED PART OF THE SHIP.)

339. The Pikemen should arrange themselves in rear of those armed with swords, and in situations which will allow them to rest the points of their pikes on the hammocks or rail, and cover that part of the ship and the parts where the assault is expected. The marines, with their muskets loaded and bayonets fixed, may be formed behind the Pikemen, or at any other place from which their fire on an assailing enemy may be most effective and least dangerous to our own men.

340. The moment an enemy commences his assault, the order—

"REPEL BOARDERS!"

Should be given, and every effort made to prevent his gaining or retaining any foothold in the ship.

It will, of course, be important to bring grape and musketry to bear at once upon the enemy's men when they are assembled for boarding, if they should be discovered in time.

The men left at the guns must be watchful that the enemy does not gain an entrance through ports or quarter-galleries.

341. In case the enemy should effect a landing on the decks, the pikes may, from their length and the press of the contending parties, become less efficient than the swords. Whenever this occurs, the sword must be brought into full use, as the most efficient weapon for attack or defence at such close quarters.

342. The howitzers, mounted on the field-carriage and charged with canister, should be ready for use in case of the enemy's getting a footing on the spar-deck.

343. Unless induced by circumstances to attempt to board the enemy first, the most favorable opportunity for attack will present itself when his men have been driven back; and to guard against the contingency of being repulsed, in all cases where the Boarders are called to attack the enemy they are to be covered by the marines and all the available small-arm men on deck.

344. The men, and especially the Boarders and Pikemen, must be exercised and encouraged to practise with the single stick and sword, as far as circumstances will allow.

GENERAL PRECAUTIONS

TO BE OBSERVED IN TIME OF WAR.

345. In time of war, unless otherwise ordered by the Admiral commanding, every cruiser should at nightfall carefully extinguish all lights not absolutely necessary, and shade all those that are indispensable, that they may not be visible from out-board.

346. The watch on deck shall be mustered at their quarters, and the guns so far cast loose as the state of the weather will permit.

347. The officer of the watch shall, on taking the deck, ascertain that the means of making and answering signals and a competent signal-man are always at hand. It is his duty to make himself fully acquainted with all the day and night signals.

348. Before making night-signals, every light should be extinguished or covered.

349. Particular care is required, when it is expedient to conceal the lights of the ship, to look well to the cabin and wardroom lights. Ports and air-scuttles there, are more apt to be imperfectly masked or thrown open heedlessly by servants.

350. If in company with other vessels, two guns in each broadside must always be ready for making signals of immediate or urgent necessity.

351. No vessel cruising shall allow a strange or suspected vessel to come within gunshot, without the watch being at quarters and ready to open fire.

352. It is the duty of the officer of the watch to immediately inform the Commander of all suspicious movements which he may observe, or which may be reported to him, and of all unknown vessels or boats that may appear in sight.

353. Speed being one of the principal elements of military force, Steamers will, on going into action, have all the fires lighted and in condition to make steam.

The beat to quarters for action is therefore a signal to start fires in all the furnaces not in operation.

354. If at anchor singly or in squadron in our own waters, in those of an ally, or elsewhere within our right to exercise control, and where liable to an attack by an enemy in any form, no strange or suspicious vessel must be permitted to be underway between evening gun-fire and daylight. The nearest vessel must require her to anchor, and send an armed boat to ascertain her character.

355. If the Senior Officer opens fire on any vessel, the nearest vessel in a position to do so will also be prepared to fire to bring her to, if signalled. All boats to be hailed and ordered alongside to give the countersign, or to lay off on their oars to be visited by the guard-boat.

356. If at anchor in or about an enemy's waters, steam shall be kept up at night at all times, sufficient to move the vessel at half speed at least, and the engines moved certainly every hour, or oftener if necessary, to keep them in a condition for immediate service. In vessels with single engine, liable to be caught on the centres, means for turning it off to be kept at hand, and suitable persons stationed to attend to it.

357. The cable must be kept ready in every respect for slipping, with a stopper forward of the bits, and even unshackled, if the weather will permit, with a steady man stationed to slip or cut as may be requisite.

358. Some of the guns, and those such as may be brought most conveniently to bear upon the probable quarter of attack, must be loaded with grape and some with canister, and ample supplies for reloading be kept on deck. Appliances for extreme depression should be at hand for broadside-guns; a gun here and there depressed extremely. The Howitzers, on field-carriages, in place, and loaded with canister. Pikes distributed about the decks ready for use.

359. Small vessels lying in rivers or sounds, and liable to be attacked and carried by boarding, will have their boarding-nettings of wire rope secured at evening quarters; the guns cast loose; the watch completely armed and on the alert, and every preparation made for instantly slipping and getting under way and repelling boarders.

360. At the hail by the look-out of "Boat ahoy," without further orders or the striking of the bell, the engine should be started immediately, the slip-rope cut, and all boats are to be received while under way and the crew at quarters.

361. It is important that the arms of the watch below should be as accessible as possible, that no confusion may take place in case of being summoned suddenly. The engineer and watch in the fire and engine room must always be armed.

362. On dark, foggy, or hazy nights, no lights should be shown, nor the bell struck or watch piped to indicate the position of the vessel.

The look-outs, increased and cautioned to greater vigilance, relieved at least hourly, and visited by either the Commander or Executive Officer half hourly.

363. The safety of small vessels at night requires that they shall be always either underway, or else in readiness to be got so at the shortest warning.

364. If circumstances prevent this, the greater the necessity for increased precaution and vigilance, and therefore a picket or advice boat should be kept out in the direction from which attack may be expected; and, indeed, the resort of picket-boats should be observed whenever practicable and at all likely to be of service.

365. In case of sending away a boat that is to return before sunrise—which is always to be avoided, if possible—a concerted signal, such as a certain number of flashes of a light, preceded or followed by the firing of a certain number of muskets, must be made at the distance from the vessel of about one-half mile, the number to be agreed upon for each night as the boat leaves the vessel. A countersign is also to be given; but if not understood by the look-out, he is to call out "Enemy," at the same time warning the boat to keep off, at which the vessel will be got underway at once.

366. The boat must be furnished with suitable and reliable fireworks or other means for announcing instantly the approach of an enemy, and no excuse can be taken for a failure on the part of the picket to give the alarm. The capture of the picket-boat is a minor consideration.

367. When confident of being able to repel any force, the boat should return to give timely notice for preparation; and in this case it may be expedient to be prepared to light up the adjacent waters, to enable an effective fire to be opened on the enemy from guns and howitzers.

368. Commanding Officers of vessels situated as described in Art. 359, are required to practise their crews, by going on deck and hailing, "Boat ahoy," at least once a week.

The time taken for the execution of this order to be noted on the log.

369. In times of anticipated attack from rams or mail-clad vessels upon a fleet or single ship, it is recommended to load the guns with maximum charges and solid shot; but where there is doubt of the character of the assailant, the guns should only be loaded with the service powder charge having ready at hand shot, shell, shrapnell, grape, or canister, as the case may demand.

DIRECTIONS IN CASE OF FIRE.

370. In the following directions, no other object is proposed than to notice some of the more prominent and common preparations which may be generally made, and the measures to be adopted in vessels on the alarm of fire. The variety of circumstances under which that danger may be presented can only be successfully met by properly stationed, well-trained and disciplined men, judiciously directed by the Captain, and superintended by officers whose coolness and presence of mind are proof against every form and degree of danger, which alone will enable them to adopt and execute the best plans the emergency may require.

To this end the Captain will, as soon as the crew is organized, cause a Fire-Bill to be prepared, adapted to the particular arrangements of his ship, and in accordance with these Directions, by which the crew is to be drilled once a week till expert, and after that occasionally. This fire-bill should, as far as possible, conform to the arrangement for extinguishing fire during exercise at General Quarters. Much confusion has been known to arise from requiring different duties from the same person at Fire Quarters, and in case of fire when at General Quarters.

371. Should the alarm of fire be given when the men are not at Quarters, that alarm of itself is to be considered as a call to Quarters, and the men must repair to their stations at once. This must be impressed upon the men by the Division Officers. But the ordinary call for inspection is to be given as soon as practicable, by way of enforcing the order.

The alarm will be given by the sentinel near the bell, by ringing quickly and loudly successive peals for ten or fifteen seconds, with short intervals between.

The bell is to cease, however, as soon as the drum begins to sound the call to Quarters.

Should it be deemed necessary to water and provision the boats, preparatory to lowering them, the drum will beat the usual call for provisions, when the men stationed for these purposes will promptly proceed with their duties. In this case the shot shall be drawn or discharged from the guns, to guard against accidents in leaving the vessel, should it be impossible to save her.

372. The Captain will direct the Executive Officer, and such others as he may deem proper, to visit the place of the fire, and to transmit reports to him, by officers, of its character and extent, and to suggest the measures which will most speedily and certainly subdue it, or prevent its extension.

373. He will, if at sea, cause the ship to be hove-to, or steered in such direction as will be least likely to increase the activity of the fire, or will best enable the men to use the means in their power for controlling and extinguishing it.

374. If fire should take place in a ship at anchor in port or harbor, his attention must be given to prevent the communication of the fire to other vessels or combustible objects, and to have the cables ready for slipping, boats ready, and, if advisable, springs prepared to change the position of the ship, in order to prevent danger to other vessels.

375. He will decide whether the magazines and shell-rooms shall be flooded, and give orders accordingly; whether the hammocks shall be brought up and stowed; where sentinels shall be placed, and what disposition shall be made of the sick and prisoners.

If hammocks are to be brought up, each man not a Fireman, Pumpman, Hoseman, Axeman, or Smotherer, or belonging to the Carpenter's gang, or detailed as a Sentinel over boats' falls or spirit-room, will lash and carry up two hammocks and stow them in the nettings on his way to Quarters. Blankets, or other woollen materials, when wet, afford an excellent means of smothering fire, and should be left out by the party lashing up the hammocks and collected by the Smothering party, in charge of an officer, whose duty it will be to see them properly used.

376. The Officers of the respective divisions will enforce the strictest observance of orders from those under their command, and allow no one to leave his station, unless by express orders or permission. At the same time they will direct the most trustworthy of their men to perform any particular duty within their divisions which may tend to check the spreading of the fire, or furnish the means of extinguishing it.

377. Officers of gun-deck divisions will be prompt to detach, under proper officers, men who may be directed for any particular service, or who may be called from the guns by the calls for Firemen, Sail-Trimmers, or Boarders. Should the call for Boarders be made in case of fire, the men will answer it without any other arms than their swords or battle-axes. Divisional Officers near the main or other pumps, will cause the men of their divisions to aid in rigging and working them. The ship's buckets are to be passed up to the pumps, as soon as possible, by the persons who may be stationed near them, and these and the fire-buckets and division-tubs filled. The swabs are also to be got up and thoroughly wetted.

Division-boxes, and all powder or explosive materials not in the magazines, must be taken in charge by the Quarter-Gunners and placed in the safest positions, ready to be thrown overboard if ordered.

378. The Officer commanding the Powder division will himself deliver the keys of the magazines, shell-rooms, and water-cocks to the Gunner, his Mate, and the men stationed at the water-cocks, and see that they are prepared to flood the magazines, if orders should be given to that effect; but he must take especial care that the magazines, passages, and shell-rooms are kept closed until orders to open them are received from the Captain.

379. He will also take care that the air-ports are immediately closed, and all other means adopted for diminishing currents of air, especially if there should be a hope of confining the fire to the lower parts of the vessel.

He will at once have the hose led from the bilge-cock, the cock turned, and, if the forcing-pump or engine is worked below the gun-deck, will see it manned and worked by some of the men of his division.

380. The Master will cause windsails to be taken down; and, if set, courses, spanker, and all lower sails hauled close up; head, channel, and all other pumps which work on upper deck, and fire-engine, if on deck, to be rigged and worked by the men of his division stationed nearest to each of them. If practicable, sails, rigging, boats, spars, and the sides of ship must be kept wet, and every exertion made to furnish a full supply of water for extinguishing the fire. Rigging-axes and battle-axes must be ready for use, in case they should be wanted for any purpose.

381. The Chief Engineer will detail such Assistant Engineers and men as may be needed to take charge of steam-pumps, to lead out hose, and to use such other means of extinguishing the fire as may be ordered or deemed advisable. If under steam, the main engine will be slowed on the first alarm of fire, unless otherwise expressly ordered, and the steam-pumps started.

382. The Surgeon and his assistants will be in readiness to destroy, if required, all inflammable fluids, or other medical stores which would increase the fire; and to superintend the removal, if necessary, of patients who may be lame or confined to hammocks or cots.

383. Exercises, by order of the Captain, following false alarms of fire, known only to him and the Executive Officer to be false at the time of giving the alarm, may, it is believed, be resorted to with advantage, especially at night.

Such alarms furnish the best means of ascertaining practically whether the necessary preparations for extinguishing fire have been duly attended to; and what degree of silence, calmness, and promptitude may be expected from officers and men in repairing to their stations, as well as in the performance of their duties in a real case of fire.

False alarms, frequently repeated, may perhaps lead some of the men to move slowly, under the impression that every alarm given is false, and merely intended for exercise; and this impression may be entertained even when a fire has actually taken place. This evil would, however, be comparatively small, since it will be readily admitted by any one who has witnessed the effect of a fire upon a crew at sea, that the great difficulty in such cases is to obtain that necessary quiet and orderly attendance at Quarters which is essential to the success of all subsequent measures.
