The earl of Albemarle, the English ambassador at Paris, having lately died in that city, these assurances were communicated to the court of London by the marquis de Mirepoix, who resided in England with the same character which he had supported since his first arrival, with equal honour and politeness. On this occasion he himself was so far imposed upon by the instructions he had received, that he believed the professions of his court were sincere, and seriously endeavoured to prevent a rupture between the two nations. At length, however, their preparations were so notorious that he began to suspect the consequence; and the English ministry produced such proofs of their insincerity and double dealing, that he seemed to be struck with astonishment and chagrin. He repaired to France, and upbraided the ministry of Versailles for having made him the tool of their dissimulation. They referred him to the king, who ordered him to return to London, with fresh assurances of his pacific intentions; but his practice agreed so ill with his professions, that the ambassador had scarce obtained an audience to communicate them, when undoubted intelligence arrived, that a powerful armament was ready to sail from Brest and Rochfort. The government of Great Britain, roused by this information, immediately took the most expeditious methods for equipping a squadron; and towards the latter end of April, admiral Boscawen sailed with eleven ships of the line and one frigate, having on board a considerable number of land forces, to attend the motions of the enemy; but more certain and particular intelligence arriving soon after touching the strength of the French fleet, which consisted of twenty-five ships of the line, besides frigates and transports, with a great quantity of warlike stores, and four thousand regular troops, commanded by the baron Dieskau, admiral Holbourne was detached with six ships of the line, and one frigate, to reinforce Mr. Boscawen; and a great number of capital ships were put in commission. In the beginning of May the French fleet, commanded by Mr. Macnamara, an officer of Irish extraction, sailed from Brest, directing his course to North America; but, after having proceeded beyond the chops of the English channel, he returned with nine of the capital ships, while the rest of the armament continued their course, under the direction of M. Bois de la Mothe.
