Instruction II.  At sight of the said fleet, the vice-admiral (or he who commands in chief in the second place), with his squadron; and the rear-admiral (or he who commands in chief in the third squadron), with his squadron; are to make what sail they can to come up, and to put themselves into that order of battle which shall be given them; for which the signal shall be the union flag put on the mizen peak of the admiral’s ship; at sight whereof, as well the vice- and rear-admirals of the red squadron, as the admirals, vice-admirals, and rear-admirals of the other squadrons, are to answer it by doing the like.

Instruction III.  In case the enemy have the wind of the admiral and fleet, and they have sea-room enough, then they are to keep the wind as close as they can lie, until such time as they see an opportunity by gaining their wakes to divide the enemy’s fleet; and if the van of his majesty’s fleet find that they have the wake of any considerable part of them, they are to tack and stand in, and strive to divide the enemy’s body; and that squadron that shall pass first, being got to windward, is to bear down on those ships to leeward of them; and the middle squadron is to keep her wind, and to observe the motion of the enemy’s van, which the last squadron is to second; and both of these squadrons are to do their utmost to assist or relieve the first squadron that divided the enemy’s fleet.[2]

Instruction IV.  If the enemy have the wind of his majesty’s fleet, and come to fight them, the commanders of his majesty’s ships shall endeavour to put themselves in one line, close upon a wind, according to the order of battle.[3]

Instruction V. If the admiral would have any of the fleet to make sail, or endeavour, by tacking or otherwise, to gain the wind of the enemy, he will put a red flag upon the spritsail [sic], topmast shrouds, fore-stay, fore topmast-stay; and he who first discovers this signal shall make sail, and hoist and lower his jack and ensign, that the rest of the fleet may take notice thereof, and follow.[4]

Instruction VI.[5] If the admiral should have the wind of the enemy when other ships of the fleet are in the wind of the admiral, then, upon hoisting up a blue flag at the mizen yard, or mizen topmast, every ship is to bear up into his wake or grain, upon pain of severe punishment.

If the admiral be to leeward of the enemy, and his fleet or any part thereof be to leeward of him, to the end such ships that are to leeward may come up in a line with the admiral (if he shall put a flag as before and bear up); none that are to leeward are to bear up, but to keep his or their ship’s luff, thereby to give his ship wake or grain.

If it shall please God that the enemy shall be put to run, all the frigates are to make all the sail that possibly they can after them, and to run directly up their broadsides, and to take the best opportunity they can of laying them on board; and some ships which are the heavy sailers (with some persons appointed to command them) are to keep in a body in the rear of the fleet, that so they may take care of the enemy’s ships which have yielded, and look after the manning of the prizes.[6]
