Hart, an iron-clad steamer under Lt. E. Montague, CSA, transported stores, ordnance and troops in support of Camp Bisland on Bayou Teche and in Berwick Bay, La. On 1 November 1862 she gallantly went to the assistance of Confederate gunboat J. A. Cotton in her unequal contest with Federal gunboats until ordered to resume her tow of a government sugar barge up Bayou Teche. Later in the month she transported from Camp Bisland to Petite Anse Island, four guns of a Confederate army battery for operations against Federal gunboats. She was sunk on 14 April 1863 to avoid capture when Camp Bisland, Bayou Teche, La., fell to the combined efforts of Federal gunboats and troops under Maj. Gen. N. P. Banks, USA. On 28 July 1863, an intelligence report from USS Clifton stated that Hart had been nearly raised but sunk again on reappearance of the Federal gunboats.
