During the Third Anglo-Dutch War, de Ruyter returned to Martinique in 1674, this time with the intent to capture Fort Royal. Calm winds and French booms prevented him from sailing his fleet of 30 warships, nine supply ships, and 15 transports into the harbor. The French repulsed his attempt to land his 3,400 troops, causing him to lose 143 men, at a cost of 15 French lives.
