The fourth Inca, an iron tug, was built in 1879 by J. H. Dialogue & Sons, Camden, N. J.; and acquired by the Navy 31 July 1918. She commissioned 2 August 1918.
The tug was assigned to the 6th Naval District, and operated until after World War I ended at Parris Island Marine Barracks, S.O. She was stricken from the Navy List 1 February 1919.
Liberty ships Henry L. Abbott and William B. Allison were both acquired by the Navy from WSA 30 July 1945 for use as floating storage. On 14 July 1945 Henry L. Abbott was renamed Gamage and classified IX-227; on 6 August 1945 William, B. Allison was renamed Inca and classified IX-229. However, when the former Henry L. Abbott was subsequently found unfit for service, her acquisition was canceled; and the name, Gamage (q.v.), and the classification, IX-227, were given to the former William B. Allison. Nevertheless, occasional references to Inca (IX-229) appear in the ComServDiv 104 War Diary until January 1946.
