If a squadron or any detachment be directed by signal to gain or keep the wind of the enemy, the officer commanding it is to act in such manner as shall in his judgment be the most effectual for the total defeat of the enemy; either by reinforcing those parts of the fleet which are opposed to superior force, or by attacking such parts of the enemy's line as, by their weakness, may afford reasonable hopes of their being easily broken, XXIV.

When the signal (30) is made to extend the line from one extremity of the enemy's line to the other, though the enemy have a greater number of ships, the leading ship is to engage the leading ship, and the sternmost ship the sternmost of the enemy; and the other ships are, as far as their situation will admit, to engage the ships of greatest force, leaving the weaker ships unattacked till the stronger shall have been disabled.[8] XXV.

If the admiral, or any commander of a squadron or division, shall think fit to change his station in the line, in order to place himself opposite to the admiral or the commander of a similar squadron or division in the enemy's line, he will make the Signal 47 for quitting the line in his own ship, without showing to what other part of the line he means to go; the ships ahead or astern (as circumstances may require) of the station opposed to the commander in the enemy's line are then to close and make room for him to get into it.

But if the admiral, being withdrawn from the line, should think fit to return to any particular place in it, he will make the signal No.

269 with the distinguishing signal of his own ship, and soon after he will hoist the distinguishing signal of the ship astern of which he means to take, his station.
