"Nathan George "Shanks" Evans (February 3, 1824 - November 23, 1868) was a captain in the 2nd U.S. Cavalry who became a brigadier general in the Confederate States Army during the American Civil War.
In the summer of 1863, Evans' Brigade was assigned to General Joseph E. Johnston's army during the Vicksburg Campaign. After this campaign, the brigade returned to Charleston where Evans quarreled with his superior, General Roswell S. Ripley, who had him tried for disobedience of orders. Following Evans' acquittal, General P.G.T. Beauregard still considered Evans incompetent and would not return him to command. He was finally reinstated to command in the spring of 1864, but was severely injured in a buggy accident in Charleston as he was preparing to take his brigade north to the Petersburg Campaign. Evans' Brigade, renamed for its new commander, Brigadier General Stephen Elliott, Jr., would soon find itself in the Petersburg trenches directly above the Union mine and suffer heavy casualties at the Battle of the Crater."
