The Battle of the Thousand Islands was fought from August 16-24, 1760 in the upper St. Lawrence River. For the British, they had 11,000 troops and 700 Iroquois Indians as for the French, they had 300 regulars, militia, and sailors. The small French unit was able to hold off the much larger British troops for a little over a week, sinking two British ships and almost sinking a third in the process.
On August 7th, French lookouts spotted two incoming British ships and immediately rowed back to the fort. The two ships followed but got lost in the maze of islands, and were not found for several days. At dawn on August 17th, two British ships attacked a French ship but the French ship was actually able to hold out for three hours. In those three hours, it shot 72 grapeshots, damaging the two ships. Even though it damaged the British ships, the French ship was forced to surrender as 15 of its crew members were killed in the fighting. On August 19th, Amherst began firing upon the fort. One of the British ships, the Williamson, was hit 48 times by the French guns in the fort. Amherst decided to cease fire for the night and resume at dawn. As dawn came around, the three British ships the Williamson, the Onondaga, and the Mohawk began firing upon the fort with a combined 50 guns. The French guns, however, managed to sink the Williamson and the Onondaga. The British troops on surrounding islands then switched to "hot shot", which was used to start fires within the fort. The French held out until August 24th when they ran out of ammunition. The British lost 26 and had 47 wounded and the French had 275 of its original 300 killed or wounded.
