21 May, 1943
The Italian submarine Gorgo was most likely sunk off Oran by the US destoyer USS Nields.

USS Nields was on a anti-submarine patrol out off Oran when a British aircraft reported a submarine contact. At 1716hours Nields established a sound contact. At 1718hours she dropped a pattern of 9 depth charges. At 1723 the sound contact was regained and another 9 depth charges were dropped. At 1731 and 1741hours more depth charges were dropped. Within seconds of the last attack, oil patches were observed. This, most likely, meant the end of the Italian submarine Gorgo.
