July 4, 1977, George Rogers Clark defeated the British and captured Kaskaskia near the Mississippi River. Clark had been organizing the defense of the sparsely settled Kentucky region against British and Indian ally raids. In October 1777, Clark puts before Virginia governor Patrick Henry a plan to capture several British posts in the Illinois country, of which Kaskaskia is one. Clark and about 175 men take the fort and town, which is inhabited mainly by French settlers. Clark convinces them and their Indian allies on the Wabash River to support the American cause.
