On February 20, 1944, while sailing from Nisida to Anzio, LST-348 was struck on her port side by a torpedo fired from the German U-boat U-410. LST-348 was struck once more on her port side before orders were received to abandon ship. The ship was the ordered to be scuttled starting a large fire on board which would be extinguished once a third and final torpedo would sink the ship. Twenty-four members of the ship's crew perished, while 79 were rescued. Two battle stars were awarded to the ship for its World War II service. Following the ship's sinking, an investigation found that at the time of the attack, LST-348 had not been at the required readiness condition. Her guns had not been manned and only limited lookouts had been stationed. Jennings was subsequently reprimanded for these oversights.
