In the course of the letter he tells her, 'Defence and Agamemnon are upon the look out nearest to Cadiz; ...

Colossus and Mars are stationed next.

The above four and as many more of us are now to form an advanced squadron; and I trust by the morning we shall all be united and in sight of the enemy.' Clearly then Nelson must have issued some modification of the dual 'order of battle and sailing.' Many years later in a note upon the battle which Codrington dictated to his daughter, Lady Bourchier, he says that on the 20th, in spite of Collingwood's advice to attack at once, Nelson 'continued waiting upon them in two columns according to the order of sailing and the memorable written instruction which was given out to all the captains.'[23] Later still, when a veteran of seventy-six years, he gave to Sir Harris Nicolas another note which shows how in his own mind he reconciled the apparent discrepancy between the dual and the triple organisation.

It runs as follows: 'In Lord Nelson's memorandum of October 9, 1805, he refers to "an advanced squadron of eight of the fastest sailing two-decked ships" to be added to either of the two lines of the order of sailing as may be required; and says that this advanced squadron would probably have to cut through "two, three or four ships of the enemy's centre so as to ensure getting at their commander-in-chief, on whom every effort must be made to capture";[24] and he afterwards twice speaks of the enemy's van coming to succour their rear.

Now I am under the impression that I was expressly instructed by Lord Nelson (referring to the probability of the enemy's van coming down upon us), being in the Orion, one of the eight ships named, that he himself would probably make a feint of attacking their van in order to prevent or retard it.' Here then would seem to be still further confusion, due to a failure to distinguish between the leeward and windward form of attack.
