Ches rides up to the cabin on a dark horse and switches his saddle to the light horse that is there. When he rides into town, he is again on the dark horse.
After Dan's horse was shot and killed, Johnny rides up on a horse with a white mark the length of its head and gives it to Dan. When Dan is next seen on the horse, it is the horse that had been killed earlier - that had a small white mark near the top of its head. When Dan leaves the cabin, he is on Johnny's horse again.
