When sailing in a line of battle, one ship ahead of another, and I would have the ship that leads with either the starboard or larboard tacks aboard to alter her course in order to lead down to the enemy, I will hoist a Dutch jack under my flag at the mizen topmast-head and fire two guns.  Then every ship of the squadron is to steer for the ship of the enemy that from the disposition of the two squadrons must be her lot to engage, notwithstanding I shall keep the signal for the line ahead flying, making or shortening sail in such proportion as to preserve the distance assigned by the signal for the line, in order that the whole squadron as soon as possible may come to action at the same time.[2]

ED. HAWKE.

Additional Signals.

If upon seeing an enemy I should think it necessary to alter the disposition of the ships in the line of battle, and would have any ships change station with each other, I will make the signal to speak with the captains of such ships, and hoist the flag chequered red and blue on the flagstaff at the mizen topmast-head.[3]

[2] This article was presumably issued by Hawke when in July 1756 he superseded Byng in the Mediterranean.  It seems designed to prevent a recurrence of the errors which lost the battle of Minorca, where the British van was crushed by coming into action long before the centre and rear.  It is not in the Additional Instructions of 1759, but reappears in a modified form in those of 1780.

I. In case of meeting with a squadron of the enemy’s ships that may be less in number than the squadron under my command, if I would have any of the smaller ships quit the line, that those of the greatest force may be opposed to the enemy, I will put abroad the signal for speaking with the captains of such ships as I would have leave the line, and hoist a flag, striped yellow and white, at the flagstaff at the main topmast-head; then the next ships are to close the line, and those that have quitted it are to hold themselves in readiness to assist any ship that may be disabled, or hard pressed, or to take her station, if she is obliged to go out of the line:  in which case, the strongest ship that is withdrawn from the line is strictly enjoined to supply her place, and fill up the vacancy.

II.  And in case of meeting with any squadron, or ships of war of the enemy that have merchant-men under their convoy, though the signal for the line of battle should be out, if I would have any of the frigates that are out of the line, or any ship of the line fall upon the convoy, whilst the others are engaged, I will put abroad the pennant for speaking with the captain of such ship or ships, and hoist the flag above mentioned for quitting the line, with a pennant under it; upon which signal, such ship or ships are to use their utmost endeavours to take or destroy the enemy.
