25th January 1942: U-boat versus merchantman in the Atlantic – Hardegen’s U-123 sinks British ship CULEBRA with deck gun
Deck gun ready and opened fire. The first shots hit the stern, then one each under the bridge and in the engine room. Steamer mans the gun and fires. The firing pin of our MG C30 is broken, so we fired with the deck gun at his gun. Several hits underneath, but he continues to fire until a direct hit struck the pivot. Gun crew out of action, the barrel can’t be moved anymore. We received 5 hits, which did not penetrate the pressure hull. Because they hit very low, I assume that they fell short, burst on the surface and only the splinters hit our hull. Some shots passed between conning tower and deck gun, one could hear them whistling past.
