In this historical novel by Max Crawford, the U. S. 2nd Cavalry rolls into Texas in the 1870s with orders to keep the peace and persuade the fierce Comanches to move quietly onto the reservation. Captain Philip Chapman tells a tale of high adventure: the hardships of a forced cavalry march, an ambush by the Comanches, an idyllic summer camp at the Caballo Ranch, the epic trek made by Chapman and his K Troop across the Ilano estacado, and defeat of Tehana Storm, legendary half-white Comanche chieftain, in the decisive battle at Palo Duro Canyon.
