Battle of Sluys

naval battle during the Hundred Years' War

The Battle of Sluys (/ˈslɔɪz/; Dutch pronunciation: [slœys]; 1340) was an early and important naval battle of the Hundred Years' War. The English attacked near the port of Sluis and destroyed most of the French fleet. This made it impossible for France to invade England. Nearly all the fighting afterward took place on land in France.
