I. The chief purposes for which a fleet is formed in line of battle are, that the ships may be able, to assist and support each other in action; that they may not be exposed to the fire of the enemy’s ships greater in number than themselves, and that every ship may be able to fire on the enemy without risk of firing into the ships of her own fleet.

II.  On whichever tack the fleet may be sailing, when the line of battle is formed, the van squadron is to form the van, the centre squadron the centre, and the rear squadron the rear of the line, unless some other arrangement be pointed out by signal.  But if a change of wind, or tacking, or wearing, or any other circumstance, should alter the order in which the line of battle was formed, the squadrons are to remain in the stations in which they may so happen to be placed, till the admiral shall direct them to take others.

III.  When the signal is made for the fleet to form the line of battle, each flag officer and captain is to get into his station as expeditiously as possible; and to keep in close order, if not otherwise directed, and under a proportion of sail suited to that carried by the admiral, or by the senior flag officer remaining in the line, when the admiral has signified his intention to quit it.

IV.  In forming the line of battle, each ship should haul up a little to windward rather than to leeward of her second ahead, as a ship a little to leeward will find great difficulty in getting into her station, if it should be necessary to keep the line quite close to the wind; and it may also be better to form at a distance a little greater, rather than smaller, than the prescribed distance, as it is easier to close the line than to extend it.

V. If the admiral should haul out of the line, the ships astern of him are to close up to fill the vacancy he has made, and the line is to continue on its course, and to act in the same manner as if the admiral had not left it All signals made to the centre will be addressed to the senior officer remaining in it, who, during the absence of the admiral, is to be considered as the commander of the centre squadron.

VI.  The repeating frigates are to be abreast of the commanders of the squadrons to which they belong, and the fireships and frigates to windward of their squadrons, if no particular station be assigned to them.

VII.  When the signal to form a line of bearing for either tack is made, the ships (whatever course they may be directed to steer) are to place themselves in such a manner that, if they were to haul to the wind together on the tack for which the line of bearing is formed, they would immediately form a line of battle on that tack.  To do this, every ship must bring the ship which would be her second ahead, if the line of battle were formed, to bear on that point of the compass on which the line of battle would sail, viz. on that point of the compass which is six points from the direction of the wind.
