    William Slaper: 7th Cavalry Promotion Document for this Controversial Little Bighorn Survivor. This 1879 document elevates Slaper from private to corporal, and is signed by Colonel S. D. Sturgis. Sturgis was detached to St. Louis from the 7th at the time of Little Bighorn, but returned to take command and led the regiment in the Nez Perce War of 1877.

    Slaper was one of the "greenest" recruits in the 7th Cavalry when the regiment took the field in spring of 1876, and was assigned to "M" Company under Major Marcus Reno. In 1920, he gave a detailed interview recounting the events of the two-day fight from his perspective. Slaper had only praise for Reno, who he felt was cool, collected, and brave under the ongoing hostile fire. He was less charitable toward Custer, who he felt had pushed his men and horses to exhaustion in order to arrive first to engage the enemy.

    His promotion document is in very good condition, showing only modest soiling and aging. 14.5" x 9.75".
    From the Glenwood Swanson Collection.

    We had a wonderful time in New York during the October 2013 Historical Manuscripts auction that featured my mother’s papers collected during her tenure as Martin Luther King, Jr.’s secretary. In fact, the entire experience from beginning to end has been a pleasure.
