On September 8, 1781, the Battle of Eutaw Springs, the last major battle in the Carolinas, was Washington's final action. Midway through the battle, Greene ordered Washington to charge a portion of the British line positioned in a blackjack thicket along Eutaw Creek. The thicket proved impenetrable and British fire repulsed the mounted charges. During the last charge, Washington's mount was shot out from under him, and he was pinned beneath his horse. He was bayoneted and taken prisoner, and held under house arrest in the Charleston area for the remainder of the war.
