It was now nearly one o'clock. The action so far had consisted, first, in piercing the enemy's line, cutting off the van and greater part of the centre from the rear; and, second, in a cannonade between two columns passing on opposite parallel courses,—the Spanish main division running free, the British close to the wind. Naval history abounds in instances of these brushes, and pronounces them commonly indecisive. Jervis, who had seen such,[144] meant decisive action when he ordered the "Culloden" to tack and follow the enemy. But a stern chase is a long chase, and the Spanish ships were fast sailers. Some time must pass before Troubridge and his companions could overtake them; and, as each succeeding vessel of the British line had to reach the common point of tacking, from which the Spaniards were steadily receding, the rear of Jervis's fleet must be long in coming up. That it was so is proved by the respective losses incurred. It has, therefore, been suggested that the admiral would have done well to tack his whole fleet, or at least the rear ships together, bringing them in a body on the Spanish van. The idea is plausible, but errs by leaving out of the calculation the Spanish lee division, which was kept off by the British rear ships. Those eight lee ships are apt to be looked on as wholly out of the affair; but in fact it was a necessary part of Jervis's combination to check them, during the time required to deal with the others. Admiral Parker, commanding in the van, speaks expressly of the efforts made by the Spanish lee division to annoy him, and of the covering action of the British rear.[145]
Thus, one by one, the British ships were changing their course from south by west to north-north-east in pursuit of the Spanish main division, and the latter was gradually passing to the rear of their enemy's original order. When they saw the sea clear to the south-east, about one o'clock, they bore up, altering their course to east-south-east, hoping to pass behind the British and so join the lee division. Fortunately for Jervis, Nelson was in the third ship from the rear. Having fully divined his chief's purpose, he saw it on the point of defeat, and, without waiting for orders, wore at once out of the line, and threw the "Captain," alone, in front of the enemy's leading ships. In this well-timed but most daring move, which illustrates to the highest degree the immense difference between a desperate and a reckless action, Nelson passed to the head of the British column, crossing the bows of five large Spanish vessels, and then with his seventy-four engaged the "Santisima Trinidad," of one hundred and thirty guns, the biggest ship at that time afloat. The enemy, apparently dashed by this act of extraordinary temerity, and as little under control as a flock of frightened sheep, hauled up in a body again to north-north-east, resuming what can only be described as their flight.
