USS Winnebago (1863)

The USS Winnebago (1863) was a twin-screw, ironclad river monitor built for the United States Navy during the American Civil War. She was part of the Milwaukee class of monitors, also sometimes called the Winnebago class. These monitors were designed for service on the rivers and shallow coastal waters of the Confederacy.

Winnebago was built by James B. Eads in St. Louis, Missouri, and commissioned on 12 April 1864. Throughout her active service, Winnebago was assigned to the West Gulf Blockading Squadron.

During the Civil War, Winnebago participated in the Battle of Mobile Bay in August 1864, playing a key role in the Union victory. She engaged Confederate ironclads and fortifications, contributing to the capture of Mobile Bay. Following the battle, she remained on duty with the West Gulf Blockading Squadron, patrolling the waters around Mobile.

After the conclusion of the Civil War, Winnebago was decommissioned in July 1865. She was subsequently sold into private ownership in November 1869.
