[3] The instructions referred to are the 'General Instructions for the conduct of the fleet.' They are the first of the various sets which the Signal Book contained, and relate to books to be kept, boats, keeping station, evolutions and the like. Article IX. is 'If from any cause whatever a ship should find it impossible to keep her station in any line or order of sailing, she is not to break the line or order by persisting too long in endeavouring to preserve it; but she is to quit the line and form in the rear, doing everything she can to keep up with the fleet.'
[4] See at p. 235, as to the new sailing formation in three columns.
[5] It should be noted that this is an important advance on the corresponding Article IX. of the previous instructions, and that it contains a germ of the organisation of Nelson's Trafalgar memorandum.
[6] The continued insistence on fireship tactics in this and Articles XX. and XXI. should again be noted, although from 1793 to 1802 the number of fireships on the Navy List averaged under four out of a total that increased from 304 to 517.
[7] It should be remembered that at this time there were no davits and no boats hoisted up. They were all carried in-board.
[8] This is a considerable modification of the signification of the signal; see supra, p. 263.
NELSON'S TACTICAL MEMORANDA
INTRODUCTORY
The first of these often quoted memoranda is the 'Plan of Attack,' usually assigned to May 1805, when Nelson was in pursuit of Villeneuve, and it is generally accompanied by two erroneous diagrams based on the number of ships which he then had under his command. But, as Professor Laughton has ingeniously conjectured, it must really belong to a time two years earlier, when Nelson was off Toulon in constant hope of the French coming out to engage him.[1] The strength and organisation of Nelson's fleet at that time, as well as the numbers of the French fleet, exactly correspond to the data of the memorandum. To Professor Laughton's argument may be added another, which goes far actually to fix the date. The principal signal which Nelson's second method of attack required was 'to engage to leeward.' Now this signal as it stood in the Signal Book of 1799 was to some extent ambiguous. It was No. 37, and the signification was 'to engage the enemy on their larboard side, or to leeward if by the wind,' while No. 36 was 'to engage the enemy on their starboard side if going before the wind, or to windward if by the wind.' Accordingly we find Nelson issuing a general order, with the object apparently of removing the ambiguity, and of rendering any confusion between starboard and larboard and leeward and windward impossible. It is in Nelson's order book, under date November 22, 1803, and runs as follows:
'If a pennant is shown over signal No. 36, it signifies that ships are to engage on the enemy's starboard side, whether going large or upon a wind.
