 Many Arkansas troops participated in the last Confederate offensive operation in the Trans-Mississippi Department, when Price led a large cavalry raid into Missouri in the fall of 1864.Following Price's defeat at the Battle of Westport on October 23, most of the Arkansas cavalry units returned to the state and were furloughed for the remainder of the war.On April 9, 1865, the Third Arkansas was among the regiments that surrendered with the Army of Northern Virginia at Appomattox.
