When first published in 1935, On the Border with Mackenzie, or Winning West Texas from the Comanches by Capt. Robert G. Carter, quickly became known as the most complete account of the Indian Wars on the Texas frontier during the 1870s. And even today it still stands as one of the most exhaustive histories ever written by an actual participant in the Texas Indian Wars-one who rode with the legendary Col. Ranald Mackenzie. L. F. Sheffy refers to On the Border with Mackenzie as "a splendid contribution to the early frontier history of West Texas . . . a story filled with humor and pathos, tragedies and triumphs, hunger and thirst, war and adventure."
