At Quiberon, Captain Ayscough was selected by Sir Edward Pellew, now Viscount Exmouth, to command a party of seamen, intended to assist at the storming the enemy’s works. Circumstances, however, arose which frustrated the plan of operations, and his orders were consequently countermanded at the very moment when he was about to proceed with scaling ladders and every thing necessary to carry them into execution.

Duckworth spoke of him to his former distinguished Admiral:–
