On June 30, 1778, Lt. Col. George Rogers Clark and his troop of 170 volunteers, principally Virginians, camped near Indian Point while marching from Fort Massac to attack the British post at Kaskaskia. This was the first of five campsites on that march. Clark's men would take the post at Kaskaskia and later the British fort at Vincennes, Indiana. This work helped secure the Illinois Territory for the United States during the Revolutionary War.
