ダウンフォール作戦
SS "Simmons Victory" was tasked with delivering ammunition, which was loaded at the San Francisco-area navy munitions depot at Port Chicago for Operation Downfall, the invasion of Japan. According to Harry Morgan, who served as an engineer on the ship, the "Simmons Victory" arrived in the Philippines about six weeks before V-E Day on 8 May 1945. She made one trip north in support of Operation Downfall and returned to the Philippines. She was in the Leyte Gulf when Japan surrendered on 15 August 1945.
