The destruction or dispersal of the Toulon fleet stopped the invasion of England, though the five ships that got into Cadiz remained a matter of anxiety to Sir Edward Hawke, who cruised before Brest. Choiseul, balked of his main object, still clung to the invasion of Scotland. The French fleet at Brest, under Marshal de Conflans, a sea officer despite his title, numbered twenty sail-of-the-line, besides frigates. The troops to be embarked are variously stated at fifteen to twenty thousand. The original purpose was to escort the transports with only five ships-of-the-line, besides smaller vessels. Conflans insisted that the whole fleet ought to go. The minister of the navy thought that the admiral was not a sufficiently skilful tactician to be able to check the advance of an enemy, and so insure the safe arrival of the convoy at its destination near the Clyde without risking a decisive encounter. Believing therefore that there would be a general action, he considered that it would be better to fight it before the troops sailed; for if disastrous, the convoy would not be sacrificed, and if decisively victorious, the road would then be clear. The transports were assembled, not at Brest, but in the ports to the southward as far as the mouth of the Loire. The French fleet therefore put to sea with the expectation and purpose of fighting the enemy; but it is not easy to reconcile its subsequent course with that purpose, nor with the elaborate fighting instructions[100] issued by the admiral before sailing.
