S5 | E1: TEXAS RANGERS — "A Captain Rises"
After the Texas revolution and the Great Comanche Raid, a Tennessean named John Coffee Hays rises to prominence as the commander of the Texas Rangers. Hays, along with captains Ben McCulloch, Samuel Walker and "Bigfoot" Wallace fights bandits in the Nueces Strip and Comanches on the frontier.
The rangers are on the front lines as Mexico sends hundreds of troops into Texas. Texas responds by sending the rangers to Mexico on the disastrous Mier Expedition.
