Indiana Historical Bureau’s map of the Battle of Vincennes

Fort Sackville, located in the town of Vincennes in what is now Indiana, was a key target for American troops, and they wanted to take the fort before the British had time to strengthen it. Soldiers under American Colonel George Rogers Clark marched 180 miles (the last nine of which are shown in this map) through wet winter conditions and with little food in order to reach the fort. The long march paid off, however, as the British garrison was surprised and overwhelmed by the attack. Within two days, and with almost no casualties, the American army took the fort and renamed it Fort Patrick Henry.
