XVII. Though a ship be disabled, and hard pressed by the enemy in battle, she is not to quit her station in the line, if it can possibly be avoided, till the captain shall have obtained permission so to do from the commander of the squadron, or division, to which he belongs, or from some other flag officer. But if he should be ordered out of the line, or should be obliged to quit it, before assistance can be sent to him, the nearest ships are immediately to occupy the space become vacant, to prevent the enemy from taking advantage of it.
XVIII. If there should be found a captain so lost to all sense of honour and the great duty he owes his country, as not to exert himself to the utmost to get into action with the enemy, or to take or destroy them when engaged; the commander of the squadron, or division, to which he belongs, or the nearest flag officer, is to suspend him from his command, and is to appoint some other officer to command the ship, till the admiral's pleasure shall be known.
XIX. When, from the advantage obtained by the enemy over the fleet, or from bad weather, or from any other cause, the admiral makes the signal for the fleet to disperse, every captain will be left to act as he shall judge most proper for the preservation of the ship he commands, and the good of the king's service; but he is to endeavour to go to the appointed rendezvous, if it may be done with safety.
XX. The ships are to be kept at all times as much prepared for battle as circumstances will admit; and if the fleet come to action with an enemy which has the weather-gage, boats, well armed, are to be held in readiness, with hand and fire-chain grapnels in them; and if the weather will admit, they are to be hoisted out, and kept on the offside from the enemy, for the purpose of assisting any ships against which fireships shall be sent; or for supporting the fireships of the fleet, if they should be sent against the enemy.[7]
XXI. The ships appointed to protect and cover fireships, when ordered on service, or which, without being appointed, are in a situation to cover and protect them, are to receive on board their crews, and, keeping between them and the enemy, to go with them as near as possible to the ships they are directed to destroy. All the boats of those ships are to be well armed, and to be employed in covering the retreat of the fireship's boats, and in defending the ship from any attempts that may be made on her by the boats of the enemy.
XXII. If the ship of any flag officer be disabled in battle, the flag officer may repair on board, and hoist his flag in any other ship (not already carrying a flag) that he shall think proper; but he is to hoist it in one of his own squadron or division if there be one near, and fit for the purpose.
XXIII. If a squadron or any detachment be directed by signal to gain or keep the wind of the enemy, the officer commanding it is to act in such manner as shall in his judgment be the most effectual for the total defeat of the enemy; either by reinforcing those parts of the fleet which are opposed to superior force, or by attacking such parts of the enemy's line as, by their weakness, may afford reasonable hopes of their being easily broken,
XXIV. When the signal (30) is made to extend the line from one extremity of the enemy's line to the other, though the enemy have a greater number of ships, the leading ship is to engage the leading ship, and the sternmost ship the sternmost of the enemy; and the other ships are, as far as their situation will admit, to engage the ships of greatest force, leaving the weaker ships unattacked till the stronger shall have been disabled.[8]
XXV. If the admiral, or any commander of a squadron or division, shall think fit to change his station in the line, in order to place himself opposite to the admiral or the commander of a similar squadron or division in the enemy's line, he will make the Signal 47 for quitting the line in his own ship, without showing to what other part of the line he means to go; the ships ahead or astern (as circumstances may require) of the station opposed to the commander in the enemy's line are then to close and make room for him to get into it. But if the admiral, being withdrawn from the line, should think fit to return to any particular place in it, he will make the signal No. 269 with the distinguishing signal of his own ship, and soon after he will hoist the distinguishing signal of the ship astern of which he means to take, his station. And if he should direct by signal any other ship to take a station in the line, he will also hoist the distinguishing signal of the ship astern of which he would have her placed, if she is not to take the station assigned her in the line of battle given out.
XXVI. When the Signal 29 is made for each ship to steer for her opponent in the enemy's line, the ships are to endeavour, by making or shortening sail, to close with their opponents and bring them to action at the same time; but they must be extremely careful not to pass too near each other, nor to do anything which may risk their running on board each other: they may engage as soon as they are well closed with their opponents, and properly placed for that purpose.
