The expedition caused much consternation among the rebels, though little was actually accomplished. The attack made on Chattanooga, June 7th and 8th, failed, and Negley's command returned.(19) Colonel Joshua W. Sill, 33d Ohio, afterwards Brigadier-General, and killed at the battle of Stone's River, commanded a brigade under Mitchel and in the Chattanooga expedition. He was an accomplished, educated officer, modest almost to a fault, yet brave and capable of great deeds. His body is buried at Chillicothe, Ohio. Mitchel's position in Northern Alabama was at all times precarious; he covered too much country; lacked concentration, and was constantly in danger of being assailed in detail; besides, his relations to Buell, his immediate commander, were not cordial. He complained frequently directly to the Secretary of War for want of support. Shortly after Buell's arrival from Corinth, the last of June, Mitchel tendered his resignation and asked to be granted immediate leave of absence, but the next day (July 2d) he was, by the Secretary of War, ordered to repair to Washington,(20) and General Lovell H. Rousseau, a Kentuckian, who also believed in a vigorous prosecution of the war, succeeded him. General Mitchel on reaching Washington was selected by President Lincoln for command of an expedition on the Mississippi, but Halleck opposed his suggestion and failed to give the necessary orders for the contemplated movement, consequently Mitchel remained inactive until September, when he was assigned the command of the Department of the South, headquarters Hilton Head. He was stricken with yellow fever and died at Beaufort, South Carolina, October 30, 1862. He is buried at Greenwood Cemetery, Brooklyn, N. Y. ( 1) Pittenger, _Capturing a Locomotive_, pp. 26, 40.
