P. G. T. Beauregard
LeMat hoped to market his adaptable revolver as a primary sidearm for dragoons and other mounted troops. He entered into a partnership with P. G. T. Beauregard (at that time a major in the U.S. Army) in April 1859 to market his handgun to the U.S. Army. Beauregard, besides being LeMat's cousin, was one of the first U.S. Army officers to resign and join the Confederacy.
