Kill one Comanche and the others would rush in thinking he had to reload and he would kill another. He had only eleven shots (lost powder horn) and lasted 3 hours until his partners came to back him up.
I have been up on Enchanted Rock a few times where Ranger Hayes performed that amazing shootout.
Admiral Nimitz was from Fredricksburg, TX and there is a nice museum there about a half hour drive away from Enchanted Rock.
