XV.  No ship is to Separate from the body of the fleet, in time of action, to pursue any small number of the enemy’s ships which have been beaten out of the line, unless the commander-in-chief, or some other flag officer, be among them; but the ships which have disabled their opponents, or forced them to quit the line, are to assist any ship of the fleet appearing to be much pressed, and to continue their attack till the main body of the enemy be broken or disabled; unless by signal, or particular instruction, they should be directed to act otherwise.

XVI.  If any ship should be so disabled as to be in great danger of being destroyed, or taken by the enemy, and should make a signal, expressive of such extremity, the ships nearest to her, and which are the least engaged with the enemy, are strictly enjoined to give her immediately all possible aid and protection; and any fireship, in a situation which admits of its being done, is to endeavour to burn the enemy’s ship opposed to her; and any frigate, that may be near, is to use every possible exertion for her relief, either by towing her off, or by joining in the attack of the enemy, or by covering the fireship; or, if necessity require it, by taking out the crew of the disabled ship; or by any other means which circumstances at the time will admit.[6]

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]
