The Influence of Sea Power Upon History, 1660-1783

Byng sailed from Portsmouth with ten ships-of-the-line only three days before the French left Toulon. Six weeks later, when he reached the neighborhood of Port Mahon, his fleet had been increased to thirteen ships-of-the-line, and he had with him four thousand troops. It was already late; a practicable breach had been made in the fortress a week before. When the English fleet came in sight, La Galissonière stood out to meet it and bar the entrance to the harbor.

The battle that followed owes its historical celebrity wholly to the singular and tragic event which arose from it. Unlike Matthews's battle off Toulon, it does afford some tactical instruction, though mainly applicable to the obsolete conditions of warfare under sail; but it is especially linked to the earlier action through the effect produced upon the mind of the unfortunate Byng by the sentence of the court-martial upon Matthews. During the course of the engagement he repeatedly alluded to the censure upon that admiral for leaving the line, and seems to have accepted the judgment as justifying, if not determining, his own course. Briefly, it may be said that the two fleets, having sighted each other on the morning of the 20th of May, were found after a series of maneuvers both on the port tack, with an easterly wind, heading southerly, the French to leeward, between the English and the harbor. Byng ran down in line ahead off the wind, the French remaining by it, so that when the former made the signal to engage, the fleets were not parallel, but formed an angle of from thirty to forty degrees (Plate VIIa. A, A). The attack which Byng by his own account meant to make, each ship against its opposite in the enemy's line, difficult to carry out under any circumstances, was here further impeded by the distance between the two rears being much greater than that between the vans; so that his whole line could not come into action at the same moment. When the signal was made, the van ships kept away in obedience to it, and ran down for the French so nearly head-on (B, B) as to sacrifice their artillery fire in great measure; they received three raking broadsides, and were
