20th Miss. Infantry Regiment was organized during the late summer of 1861 with men from Bolivar, Monroe, Noxubee, Adams, Scott, Carroll, and Newton counties. The unit moved to Virginia, then Tennessee where in February, 1862, it was captured at Fort Donelson. In this engagement it lost 19 killed of the 31 officers and 469 men present. The regiment was exchanged and assigned to Tilghman's and J.Adams' Brigade, Department of Mississippi and East Louisiana. For a time it served in the Vicksburg area, then transferred to the Army of Tennessee. Placed in J.Adams' and Lowry's Brigade, the 20th was involved in the Atlanta and Tennessee Campaigns and ended the war in North Carolina. Only a remnant surrendered on April 26, 1865. Its commanders were Colonels William N. Brown and D.R. Russell; Lieutenant Colonels D.H. Maury, Horace H. Miller, and Walter A. Rorer; and Majors William M. Chatfield, Thomas B. Graham, and C.K. Massey.
