The British flag would not be raised above Fort Sackville Feb. 25, 1779. At 10 A.M., the garrison surrendered to American Colonel George Rogers Clark. His American army, aided by French residents of the Illinois country, had marched through freezing floodwaters to gain this victory. The fort’s capture assured United States claims to the frontier, an area nearly as large as the original 13 states.
