Westerner departed St. Nazaire on 22 September 1918 and made port at Norfolk on 10 October 1918, where she loaded another cargo of U.S. Army supplies. She subsequently conducted three additional cargo-carrying voyages under the control of NOTS: two to La Pallice, France (on one occasion lifting supplies consigned to the French government), and one to Trieste, Italy, via Gibraltar. After her final NOTS voyage, Westerner made port at New York City on 6 August 1919.[5][6]
Decommissioning and disposal
Decommissioned on 21 August 1919, Westerner was simultaneously struck from the Navy list and transferred back to the U.S. Shipping Board. Oliver J. Olson & Company became the operator of the ship for the U.S. Shipping Board.
Later career
Once again SS Westerner, the ship operated commercially under Shipping Board control until laid up in the late 1920s. After that, she never returned to service and was abandoned due to age and deterioration in either late 1932 or early 1933.
