In the event of an attack having to be made from to-leeward, the idea is different.

Here the containing movement practically disappears.

The fleet is still to attack the rear and part of the centre of the enemy, but now in three independent divisions simultaneously, in such a way as to cut his line at three points, and to concentrate a superior force on each section of the severed line.

To none of the divisions is assigned the duty of containing the rest of the enemy's fleet from the outset.

It is to be dealt with at a second stage of the action by all ships that are still capable of renewing the engagement after the first stage.
