Drury served as commander of the ship of the line during the French Revolutionary Wars, during which he was heavily engaged at the Battle of Camperdown, at which a Dutch fleet was destroyed in 1797. In April 1804, Drury was promoted to Rear-Admiral and in 1808 was sent to be commander of the East Indies Station as senior admiral. Drury's command overlapped with that of Albemarle Bertie at the Cape of Good Hope and the two engaged in numerous political struggles, even appointing separate officers to command the same ships to spite one another. In November 1810, Drury was ordered to provide Bertie with a fleet of small transport ships for the Invasion of Île de France, which he accompanied and insisted on command despite orders not to infringe on Bertie's command of the operation. When Bertie was subsequently made a baronet as a reward for the successful conclusion of this operation Drury complained at length about Bertie to the Admiralty. Bertie demanded a court martial on his behaviour, which was dismissed by the Admiralty, who were becoming irritated by Drury and Bertie's squabbling. The issue remained unresolved at Drury's sudden death on 6 March 1811 on station in India.
