When it was first published in 1935, On the Border with Mackenzie, or Winning West Texas from the Comanches quickly became known as the most complete account of the Indian Wars on the Texas frontier during the 1870s, and remains one of the most exhaustive histories ever written by an actual participant in the Texas Indian Wars. The author, Capt. Robert G. Carter, a Union Army veteran and West Point graduate, was appointed in 1870 to serve as second lieutenant in the Fourth United States Cavalry stationed at Fort Concho, Texas. He was awarded the Medal of Honor in 1900 for his gallantry in action against the Indians occurring on October 10, 1871, during the battle of Blanco Canyon. Led by Col. Ranald Slidell Mackenzie, the Fourth Cavalry moved its headquarters to Fort Richardson, Texas, in 1871 where they soon became one of the most effective units on the western frontier. Among the battles and skirmishes they participated in were the Warren wagon train raid of 1871; the Kicking Bird pursuit of 1871; the Remolino fight of 1873; the Red River War of 1874-75; and the Black Hills War of 1876.
