At eight A.M. Villeneuve saw that battle could not be shunned. Wishing to have Cadiz under his lee in case of disaster, he ordered the combined fleet to wear together. The signal was clumsily executed; but by ten all had gone round and were heading north in inverse order, Gravina’s squadron in the rear. At eleven Villeneuve directed this squadron to keep well to windward, so as to be in position to succor the center, upon which the enemy seemed about to make his chief attack; a judicious order, but rendered fruitless by the purpose of the British to concentrate on the rear itself. When this signal was made, Cadiz was twenty miles distant in the north-north-east, and the course of the allies was carrying them toward it. Owing to the lightness of the wind Nelson would lose no time in maneuvering. He formed his fleet rapidly in two divisions, each in single column, the simplest and most flexible order of attack, and the one whose regularity is most easily preserved. The simple column, however, unflanked, sacrifices during the critical period of closing the support given by the rear ships to the leader, and draws upon the latter the concentrated fire of the enemy’s line. Its use by Nelson on this occasion has been much criticized. It is therefore to be remarked that, although his orders, issued several days previous to the battle, are somewhat ambiguous on this point, their natural meaning seems to indicate the intention, if attacking from to windward, to draw up with his fleet in two columns parallel to the enemy and abreast his rear. Then the column nearest the enemy, the lee, keeping away together, would advance in line against the twelve rear ships; while the weather column, moving forward, would hold in check the remainder of the hostile fleet. In either event, whether attacking in column or in line, the essential feature of his plan was to overpower twelve of the enemy by sixteen British, while the remainder of his force covered this operation. The destruction of the rear was entrusted to the second in command; he himself with a smaller body took charge of the more uncertain duties of the containing force. “The second in command,” wrote he in his memorable order, “will, after my instructions are made known to him, have the entire direction of his line.”
