U.S. Army Transport General Lyon (not to be confused with the USS General Lyon, a U.S Navy sidewheel steamer of the same era) was a screw steamer of 1026 tons built at East Haddam, Conn. in the spring of 1864 and chartered by the Federal government in March 1864. It was used as a troop transport on the eastern seaboard, taking part in the campaigns against Battery Wagner, the Bermuda Hundred and Fort Fisher.
