Why did Custer lose the battle of little bighorn?
The evidence strongly suggests that Custer was critically wounded in the first volley, and his men retreated to re-group. Whether he ever regained his senses enough to command is impossible to determine but seems unlikely given the haphazard disposition of the bodies, but he almost certainly was killed either by his own hand, or shot in the head by a comrade who did not want him to fall into the enemies hands alive.
