Timeline story
George Rogers Clark
Virginia surveyor-turned-militia leader George Rogers Clark staged at Corn Island in the Falls of the Ohio in 1778, then launched the Illinois Campaign that took Kaskaskia and Vincennes from the British.

The settlement he left behind became Louisville, chartered in 1780 and named for France’s Louis XVI. Fort Nelson later rose on the mainland as his western headquarters.

George Rogers Clark's men left Corn Island at the Falls of the Ohio on June 24, 1778, rowed down the Ohio to the old French Fort Massac, marched about 120 miles overland to take Kaskaskia on the night of July 4, and sent Bowman to take Cahokia, while Father Gibault and Leonard Helm won over Vincennes. In February 1779 Clark marched about 180 miles from Kaskaskia through flooded country to retake Vincennes, where Hamilton surrendered Fort Sackville on February 25.
About 300 miles by river to Fort Massac, about 90 miles in a straight-ish line overland (Clark's figure is about 120 miles), and about 145 straight-line miles for the winter march (usually given as about 180 miles walked), measured on the map line.
