Answer: Smiles A Lot
Bauer had just tried to shoot Smiles A Lot, but his gun misfires because it had gotten wet when Bauer jumped into the river. He then strikes Smiles A Lot with the gun butt, and moves meanacingly towards him. Wind In His Hair sees this, whoops, and charges Bauer on his horse, swinging his tomahawk, which is attached to a rope, over his head. Bauer is momentarily distracted by the charging Wind In His Hair, and as he turns back towards Smiles A Lot, he is greeted with a tomahawk chop right in the chest, courtesy of the young Smiles A Lot. Wind In His Hair whoops his approval, and rides off as Bauer slumps to the ground. Dances With Wolves kills Spivey, the soldier who repeatedly abuses and taunts him.
