American Indians always got along well with each other before the E-e-vil white man arrived!
OH, Wait!

After aquiring horses from the early Spanish conquistadores and learning to ride the Comanches were the most effective fighters/horsemen ever. Their raiding parties killed and chased the Apache far into Mexico. When US troops fought them the US troops dismounted and tried to kill them with single shot rifles while the Comanches remained on horseback and overwhelmed them by shooting 3 or four arrows to every shot that could be reloaded by the US cavalry. A great book about this is - Empire of the Summer Moon: Quanah Parker and the Rise and Fall of the Comanches, the Most Powerful Indian Tribe in American History. I recommend this book to all my Texas friends. It's a real eye-opener.
