Battle of the Little Bighorn before he died. Having isolated Reno's force and driven them away from the encampment, the bulk of the native warriors were free to pursue Custer. The route taken by Custer to his "Last Stand" remains a subject of debate. One possibility is that after ordering Reno to charge, Custer continued down Reno Creek to within about a half-mile (800 m) of the Little Bighorn, but then turned north and climbed up the bluffs, reaching the same spot to which Reno would soon retreat. From this point on the other side of the river, he could see Reno charging the village.
