This plan became known as the De Grasse – Saavedra Convention and the first objective was essentially met with the surrender of the British army under General Cornwallis at the Siege of Yorktown in September 1781. De Grasse and his fleet had played a decisive part in that victory, after which they then sailed to the Caribbean. On arrival in Saint Domingue November 1781 he was given news that the plan was given the go ahead: to proceed with the conquest of Jamaica.[74]
