November and reached Bordeaux on 18 December 1940. Bianchi sank three ships on its first BETASOM patrol from Bordeaux; but the next patrol from 30 April to 30 May 1941 was unsuccessful. After sailing from Bordeaux on 4 July 1941, Bianchi was sunk with all hands by on 5 July. Luigi Torelli Torelli (pennant number TI) was launched 6 January 1940. After one short war patrol in the Mediterranean, Torelli sailed on 31 August 1940 and passed the Strait of Gibraltar on 8 September for an Atlantic patrol to Bordeaux on 5 October. Torelli sank four ships on its first BETASOM patrol; and, after an unsuccessful second patrol, sank one ship on a third patrol. After another unsuccessful patrol, Torelli assisted the three s on a rescue mission of 254 sailors from the sunken in December 1941. Torelli sank two ships during Operation Neuland. Torelli again sailed from Bordeaux on 2 June 1942, but was twice damaged by aircraft and sought refuge in the neutral Spanish ports of Avilés and Santander, Cantabria before returning to Bordeaux on 15 July. After an extensive refit, Torelli was again damaged at sea by aircraft on 16 March 1943 and returned to Bordeaux on 3 April. Torelli was then selected for conversion to a "transport submarine" in order to exchange rare or irreplaceable trade goods with Japan. Cargo capacity of 160 tons reduced reserve buoyancy from 20–25% to 3.5–6%; and armament was reduced to defensive machine guns. Torelli sailed as a transport submarine on 18 June 1943 and reached Penang on 27 August 1943. UIT-25 Torelli was commissioned into the German Kriegsmarine as UIT-25 when Italy capitulated to the Allies in September 1943. I-504 UIT-25 was taken over by the Imperial Japanese Navy and became I-504 when Germany surrendered in May 1945. I-504 shot down a B-25 Mitchell bomber while under Japanese flag near the very end of the war in the Pacific, allegedly the last success of a Japanese naval vessel in that conflict. It was found at Kobe when Japan surrendered and scuttled by the United States Navy in Kii Suido. Alessandro Malaspina (pennant number MP) was launched 18 February 1940 and completed on 20 June 1940. Its first patrol was through the Strait of Gibraltar on 3 August for an Atlantic patrol. Malaspina sank one ship before reaching Bordeaux on 4 September. Admiral Karl Dönitz visited Malaspina on 30 September to
