Barbarigo returned to port on the night of 29 October. Again, Grossi's success was widely reported, and he was promoted to Capitano di Vascello (Captain) and awarded a second Gold Medal; he left the submarine to replace Polacchini as BETASOM commander. After the war, Grossi's actions would be the object of two enquiries in 1949 and 1962, which concluded that he and his crew had been in good faith, but stripped him of his promotions and awards. On 24 January 1943, the submarine departed for its last mission as an attack submarine, in which it sank the ships Monte Igueldo (3453 tls) on 24 February, Alfonso Pena (3540 tls) on 2 March, and Staghound on 3 March, before returning to Bordeaux on 3 April. After a period of time for repairs, as well as some replacements and retraining of crew, the submarine was converted into a transport to carry materiel between Germany and Japan in 1943, with guns, torpedoes and all but one periscope being removed; it departed Bordeaux on 16 June, with 130 tons of valuable load, but disappeared. After the war, British records showed that an unidentified submarine had been attacked and presumed sunk between 17 and 19 June, in the area where Barbarigo might have been.
