From DANFS:
LST-387 was laid down on 20 June 1942 at the Newport News Shipbuilding & Drydock Co.; launched on 28 September 1942; sponsored by Miss Roberta Adele Fitzhugh; and commissioned on 17 November 1942. LST-387 served in the European theater. On 22 June 1943, she was damaged by a German submarine torpedo, between Algiers and Bizerte, and subsequently repaired. The ship was decommissioned on 2 May 1946 and struck from the Navy list on 19 July 1946. On 22 December 1947, she was sold to the Northern Metals Co., Philadelphia, Pa., and scrapped.

It seems Rohwer is right this time.

Da steht:
22.06.43 Tank landing ships LST-333 and LST-387 (both carrying landing pontoons) are torpedoed by German submarine U-593 about five miles east of Dellys, Algeria, 36°59'N, 04°02'E. LST-333 is beached; LST-387 is towed to Dellys by tank landing craft LCT-294 and LCT-431. Damaging of these two ships hampers training for the forthcoming invasion of Sicily (Operation HUSKY).

Additional infos from me: LST-333 was beached, but later the LST slipped off and sank completely.
