This article is to be observed notwithstanding any seeming contradiction in the fourth or fifth articles of the [fighting] instructions formerly given.
9.

When the admiral would have the van of his fleet to tack first, the admiral will put abroad the union flag at the staff of the fore topmast-head if the red flag be not abroad; but if the red flag be abroad then the fore topsail shall be lowered a little, and the union flag shall be spread from the cap of the fore topmast downwards.
10.

When the admiral would have the rear of the fleet to tack first, the union flag shall be put abroad on the flagstaff of the mizen topmast-head; and for the better notice of these signals through the fleet, each flagship is upon sight of either of the said signals to make the said signals, that so every ship may know what they are to do, and they are to continue out the said signals until they be answered.

Given under my hand the 10th of April, 1665, from on board the Royal Charles.
By command of his royal highness.
WM.
