The eighth war patrol of the USS Pargo (SS-264), captained by Commander David B. Bell, was of forty-two days duration, twenty-seven of which were spent in the Sea of Japan. On August 6, 1945, the Pargo made a successful transit of the Tsushima Strait mine fields. Due to the cessation of hostilities on August 15, 1945, the Pargo had only eight days of offensive patrol in the Sea of Japan. During these eight days, the Pargo reported contact with four small escorted convoys, three of which were attacked. She also reported contact with seven sea trucks, one of which was attacked. The Pargo departed the Sea of Japan via the Tsushima Strait on September 3, 1945.
