From the vigilance of his frigates it resulted that when the look-outs of de Guichen, who passed to windward of Martinique on the 7th of May, came in sight of Gros Ilet on the 9th, it was simply to find the British getting under way to meet the enemy. During the five following days both fleets were engaged in constant movements, upon the character of which the writers of each nation put different constructions. Both are agreed, however, that the French were to windward throughout, except for a brief hour on the 15th, when a fleeting change of wind gave the British that advantage, only to lose it soon again. They at once used it to force action. As the windward position carries the power to attack, and as the French were twenty-three to the British twenty, it is probably not a strained inference to say that the latter were chasing to windward, and the former avoiding action, in favour, perhaps, of that ulterior motive, the conquest of Santa Lucia, for which they had sailed. Rodney states in his letter that, when the two fleets parted on the 20th of May, they were forty leagues to windward (eastward) of Martinique, in sight of which they had been on the 10th.
During these days de Guichen, whose fleet, according to Rodney, sailed the better, and certainly sufficiently well to preserve the advantage of the wind, bore down more than once, generally in the afternoon, when the breeze is steadiest, to within distant range of the British. Upon this movement, the French base the statement that the British Admiral was avoiding an encounter; it is equally open to the interpretation that he would not throw away ammunition until sure of effective distance. Both admirals showed much skill and mastery of their profession, great wariness also, and quickness of eye; but it is wholly untenable to claim that a fleet having the weather-gage for five days, in the trade-winds, was unable to bring its enemy to action, especially when it is admitted that the latter closed the instant the wind permitted him to do so.
On the afternoon of May 15th, about the usual hour, Rodney “made a great deal of sail upon the wind.” The French, inferring that he was trying to get off, which he meant them to do, approached somewhat closer than on the previous days. Their van ship had come within long range, abreast the centre of the British, who were on the port tack standing to the south-south-east, with the wind at east (aa, aa). Here the breeze suddenly hauled to south-southeast (wind b). The heads of all the ships in both fleets were thus knocked off to south-west (s, s), on the port tack, but the shift left the British rear, which on that tack led the fleet, to windward of the French van. Rodney’s signal flew at once, to tack in succession and keep the wind of the enemy; the latter, unwilling to yield the advantage, wore all together (w), hauling to the wind on the starboard tack, and to use Rodney’s words, “fled with a crowd of sail” (a’, a’).
