In July 1758, after Edward Hawke had decided to strike his flag and return to port over a misunderstanding at which he took offence, Anson hoisted his own flag in the first-rate and took over command of the Western Squadron again. Anson oversaw Britain's naval response to a more serious French invasion attempt in 1759. He instituted a close blockade of the French coast, which proved crippling to the French economy and ensured no invasion fleet could slip out undetected. The British victories at the Battle of Lagos in August 1759 and the Battle of Quiberon Bay in November 1759 destroyed any realistic hope of a major invasion of the British Isles.
