In 1841, members of a Sioux tribe attacked a village of 24 Delaware natives on the Raccoon river, killing all but one. The Sixou tribe lost 26 of their own in the bloody battle.

His age did not stop him, though - he gathered 500 of his best warriors and followed a trail for nearly 100 miles before encountering the merciless Sioux warriors who had killed the Delaware natives. At the end of hours of battle, 300 Sioux lay dead on the battlefield, while the Sax and Fox tribes lost just seven warriors.
