CSS Nashville was a brig-rigged, side-paddle-wheel passenger steamer that served with the Confederate Navy during the Civil War. Originally a United States Mail Service ship, the USMS Nashville was built at Greenpoint, Brooklyn in 1853. Between 1853 and 1861 she was engaged in running between New York City and Charleston, South Carolina. During the Battle of Fort Sumter, the USMS Nashville sailed into Charleston without flying the US national standard and was fired upon by the USRC Harriet Lane which marked the first shot of the naval war in the Civil War. The Nashville raised the American flag, and after the surrender of Sumter, the Nashville docked at Charleston.
