Ships happening to have been previously detached on any service, separate from the body of the fleet, when the signal for forming in order of battle is made, are not meant to be comprehended in the intention of it, until they shall first have been called back to the fleet by the proper signal.

IV.  When the fleet is sailing in line of battle ahead, the course is to be taken from the ship leading the van upon that occasion; the others in succession being to steer with their seconds ahead respectively, whilst they continue to be regulated by the example of the leading ship.[1]

V. The ships, which from the inequality of their rates of sailing cannot readily keep their stations in the line, are not to obstruct the compliance with the intent of the signal in others; nor to hazard throwing the fleet into disorder by persisting too long in their endeavours to preserve their stations under such circumstances; but they are to fall astern and form in succession in the rear of the line.

The captains of such ships will not be thereby left in a situation less at liberty to distinguish themselves; as they will have an opportunity to render essential service, by placing their ships to advantage when arrived up with the enemy already engaged with the other part of the fleet.

The ships next in succession in order of battle are to occupy in turn, on this and every other similar occasion, the vacant spaces that would be otherwise left in the line; so that it may be always kept perfect at the appointed intervals of distance.

And when the fleet is sailing large, or before the wind, in order of battle, and the admiral makes the signal for coming to the wind on either tack, the ship stationed to lead the line on that tack, first, and the others in succession, as they arrive in the wake of that ship and of their seconds ahead respectively, are to haul to the wind without loss of time accordingly.

And all the signals for regulating the course and motions of the fleet by day or night, after the signal for forming in order of battle has been made, are to be understood with reference to the continuance of the fleet in such order, until the general signal to chase, or to form again in order of sailing, is put abroad.

VI.  When the fleet is formed on any line pointed out by the compass signal, the relative bearing of the ships from each other is to be preserved through every change of course made, as often as any alteration thereof together shall be by signal directed.[2]

When, on the contrary, the signal to alter the course in succession has been put abroad, the relative bearing of the ships from each other will be then consequently changed; and any alteration of the course subsequently directed to be made by the ships together will thereafter have reference to the relative bearing last established.  The same distinction will take place so often as the alteration of course in succession, as aforesaid, shall in future recur.
