From 1868 through 1870, the Seventh US Cavalry and other military units played baseball in Kansas at their various posts and in the field. Details of several games were reported in local newspapers, as well as the New York Clipper. The Seventh Cavalry clubs, most notably Captain Frederick Benteen’s Company H, continued to play through 1875 while stationed in the South and the Dakota Territory, before the regiment was decimated at the Battle of Little Bighorn (Greasy Grass) in 1876. This essay focuses on the Seventh Cavalry’s baseball experiences in Kansas. A list of known games played by the regiment from 1868 through 1875 and several newspaper clippings of box scores are provided.
