Notes on event

At 06.34 hours on 13 Sep 1942 the unescorted and unarmed Nimba (Master M.L. Newcomb) was hit on the starboard side by two torpedoes from U-515. The first struck at the #1 hold and the second in the engine room. The first explosion ripped open the deck, blew bauxite into the air and let the forward rigging crash on deck, while the second destroyed the starboard lifeboat and caused the ship to sink within one minute. The master, 18 crew members and one Workaway seaman were lost. The U-boat erroneously reported the ship as Senta after questioning the survivors. There was no time to launch a lifeboat and only seven survivors managed to board a raft, while three others clung to wreckage and two floated in the water for 12 hours before they were all picked up by USS Barney (DD 149) at 18.30 hours the same day and landed at Port of Spain the next day.
