In March 1781, a large French fleet under the command of Comte de Grasse left the port of Brest. Most of this fleet was headed for the West Indies. Of the 26 ships of the line, one was sent to North America, and five, under the command of the Bailli de Suffren, were destined for India. The remaining twenty arrived off to Martinique on April 28. Before sailing to the lee (western) side of the island, de Grasse anchored the fleet and sent someone ashore for news. He learned that a British fleet of 17 ships of the line under Samuel Hood was blockading Fort Royal, preventing the four French ships anchored there from leaving.
