USS Milwaukee (1864-1865)

I didn't know it, but there was a double turret monitor during the Civil War named for the city of Milwaukee. According to the Naval Historical Center:

(I)n 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.
