CSS Teaser had been the aging Georgetown, D.C. tugboat York River until the beginning of the American Civil War, when she was taken into the Confederate States Navy and took part in the famous Battle of Hampton Roads. Later, she was captured by the United States Navy and became the first USS Teaser. CSS Teaser Teaser was built at Philadelphia, Pennsylvania. Purchased at Richmond, Virginia by the State of Virginia in 1861, she was assigned to the naval forces in the James River with Lieutenant James Henry Rochelle, Virginia State Navy, in command.
