On 30 July, Rose encountered the 32-gun HMS Thames, and in the ensuing battle, Sade beached Rose and scuttled her by fire to prevent her falling into British hands.
[3] In 1760, Sade captained the 54-gun Hippopotame,[6] on which he conducted a cruise in the Eastern Mediterranean from 21 June 1760 to 22 January 1761, in the squadron under Rochemore.
[9] In early 1780, Sade was given command of a 6-ship and 5-frigate division, to reinforce the Spanish fleet blockading Gibraltar.
On 2 January, a gale damaged several ships of the fleet and forced them into harbour to effect repairs, allowing Rodney to prey on Spanish shipping in the action of 8 January 1780, and on a small Spanish fleet in the Battle of Cape St. Vincent on 16 January.
[14][15][16] Sade died aboard Triomphant, off Cadiz, 18 September 1780.
