Etiwan, Etwan, Etowah, Etowan or Hetiwan, was built at Charleston, S.C., in 1834. She operated in Charleston Harbor throughout the Civil War as a transport and cargo ship between the forts and city. She was damaged by striking a torpedo in the harbor in the spring of 1863 and was run ashore to prevent her sinking. She resumed her transport duties in the fall of 1863. Etiwan was said to be the steamer moored at the wharf at Fort Johnson on 29 August 1863 when Confederate Submarine Torpedo Boat H. L. Hunley came alongside and attached mooring lines to her. Etiwan unexpectedly moved away from the wharf, drawing the submarine over on her side, and the H. L. Hunley filled and went down, drowning five seamen of CSS Chicora who formed a part of her volunteer crew. At the close of the Civil War Etiwan was found wrecked in Charleston Harbor. She was fitted for service to the Army Quartermaster Department engaged in clearing the harbor after the Civil War and was documented in April 1867 as the merchant steamer St. Helena.
