USS Milwaukee, name ship of class of four 1300-ton double-turret ironclad river monitors, was built at Carondelet, Missouri, for Civil War service in the Western Rivers area. Commissioned in August 1864, she was sent down the Mississippi to New Orleans, Lousisana, in October and assigned to the West Gulf Blockading Squadron. Later in 1864, she went to Mobile Bay, Alabama, where she spent the rest of her service career bombarding Confederate positions, clearing mines and supporting operations to isolate and capture the city of Mobile. On 28 March 1865, while engaged in an attack on Spanish Fort on the Blakely River, Alabama, USS Milwaukee struck a "torpedo" (as mines were then called) and sank. Her wreck was raised and scrapped in 1868.
