As well as securing home defense, Anson co-ordinated with William Pitt a series of British attacks on French colonies around the globe. By 1760 the British had captured Canada, Senegal and Guadeloupe from the French, and followed it up by capturing Belle Île and Dominica in 1761. In 1762 the entry of Spain into the war offered further chances for British expeditions. Anson was the architect of a plan to seize Manila in the Philippines and, using the idea and plans of Admiral Sir Charles Knowles to capture Havana. Anson had been concerned that the combined strength of the French and Spanish navies would overpower Britain, but he still threw himself into the task of directing these expeditions. The British also captured Martinique and Grenada in the French West Indies. Anson was promoted to Admiral of the Fleet on 30 July 1761. His last service was to convey Queen Charlotte to England.
