Taking an unusually long time to complete for a ship of its class, the SS Baton Rouge was ready for duty on September 24th, 1945, nearly twenty days after the Japanese surrendered. She was employed by the American Export Line for overdue assignments -- that is hauling cargo, mainly Canadian timber, whose transport was postponed due to the war. She operated from both the East and West coasts of the US during this time. As a notable incident, she was involved in a ship-to-ship collision off San Francisco on November 29, 1946, but no crew members were hurt in the incident and the vessels were quickly repaired. Placed in reserve sometime after, she will return to Merchant Marine duty at the advent of the Korean War, transporting goods, mail, food, and miscellaneous supplies for UN troops fighting on the peninsula. Reactivated in 1966 for Vietnam, her crew will take seven KIA during a transport run on the Long Tau River after coming into contact with two limpet mines. After this unfortunate incident, the Baton Rouge is essentially retired, to be scrapped in 1967.
