It appears from this account that neither Howe nor Montagu attached sufficient importance to the concentration of the British fleet. Howe's immediate pursuit might indeed be defended on the ground of the necessity to overtake Villaret, before he had effected his junction with Nielly; but, as both these admirals knew their rendezvous, while he did not, and as Villaret had three days' start, the chances all were that he would not come up before they met. Actually, one of Nielly's ships joined before Howe found him, another on the 29th, and the remainder on the 30th; thus neutralizing the advantages gained by the fine tactical efforts of the British admiral on the 28th and 29th. Had Montagu's six ships, however, come up, the full profit of the two previous days' fighting would have been preserved; and it is hard to over-estimate the effect which they would have had upon the results, even if maintained simply as a reserve. To these considerations may be added the risk of missing both fleet and convoy, by going in search of them, instead of simply taking a position near which they must pass, and there uniting the British fleet. That this was very possible is shown by the facts of the chase. "On the 27th, at 9 A.M., having got a few leagues to the northward of the latitude in which he had reason to think Villaret was cruising, Lord Howe bore up and ran to the eastward, with the wind on the starboard quarter."[93] The fleet had been running on this course, with a fair and apparently fresh wind for twenty-one hours, when the French were first seen in the south-south-east. Although no precise data are at hand, it is reasonable to conclude from the above that Howe had gone over a hundred miles to the westward of the French rendezvous, which Villaret had reached a week before.[94] If in the meantime the convoy had appeared, as it perfectly well might, Villaret would at once have sailed for Brest, and the British admiral would not improbably have lost both fleet and convoy.
The question presented is purely strategic. It was certain that the French fleet, if undisturbed, would meet the convoy; therefore after it had sailed from Brest the two objects of the British were merged into one. There was no occasion thenceforth to remain divided into two detachments. For what point precisely the convoy would aim was not known, but Brest and Rochefort marked the two extreme points of the coast line, between which it would probably arrive. The approach of so large a body of ships, tied down to a common movement, is necessarily slow. It would be as ignorant of the point where the British would concentrate, as the latter were of the rendezvous where the different French detachments were to meet. Fast single ships, well scattered to the westward, might reasonably be expected to meet it and to return to their main body in time to warn this where to look for the prey. That there were no difficulties in this line of action will not, certainly, be contended; but it was more sure and militarily sounder thus to concentrate the British force of thirty-two ships-of-the-line in a well chosen position, and with adequate lookouts, than to lead it hither and thither in search of the enemy's whereabouts. It is a singular and instructive fact that from first to last not a single British ship appears to have laid eyes on the convoy from America. Ships both of commerce and war, belonging to other bodies, were taken and retaken in the Bay of Biscay; but those coming from America wore invisible garments.
