The USS Minnesota was a wooden steam frigate of the United States Navy, launched in 1855 and commissioned in 1857. Constructed at the Washington Navy Yard on the East Branch of the Potomac River, she measured approximately 210 feet in length and was powered by both steam and sail, typical of mid-19th-century naval design. Named after the Minnesota River, she was part of a class of ships named for American rivers, including her sister ships Wabash, Colorado, Merrimack (later CSS Virginia), and Roanoke. Initially, Minnesota served in East Asia, departing Norfolk in 1857 with William B. Reed, U.S. Minister to China. During her deployment, she visited key ports in China and Japan, and helped bring Reed home after negotiations for the Treaty of Tianjin. She was decommissioned in 1859 but recommissioned at the outbreak of the Civil War in 1861, becoming the flagship of the North Atlantic Blockading Squadron. Her early Civil War service included capturing several Confederate vessels and participating in the Battle of Hatteras Inlet Batteries, which resulted in the surrender of Confederate forts. Minnesota’s most notable engagement occurred during the Battle of Hampton Roads in March 1862, where she ran aground while confronting the CSS Virginia (formerly USS Merrimack). During this pivotal naval encounter, Virginia sank the USS Cumberland and fought the USS Monitor, which arrived to assist Minnesota. Despite damage and fire onboard, Minnesota was refloated after assistance from tugboats and continued her service. Throughout the war, she participated in significant operations, including the Second Battle of Fort Fisher in 1865, which helped close the port of Wilmington, North Carolina. After decommissioning in 1865, Minnesota served as a training ship and was recommissioned multiple times, including a diplomatic cruise to Europe. She was transferred to the Massachusetts Naval Militia in 1895, and ultimately sold in 1901. Her maritime significance lies in her active Civil War service, notably her role in the first battle between ironclads, and her long service life as a flagship, training vessel, and symbol of naval innovation during a transformative period in naval history.
