ww2dbaseItalian submarine Alpino Bagnolini entered service in Dec 1939. In Jun 1940, shortly after Italy joined the European War of WW2, she became the first Italian naval vessel to sink a British warship when she sank cruiser HMS Calypso in the Mediterranean Sea south of Crete, Greece. She was relocated to the Italian submarine base in German-occupied France in the fall of 1940. In Sep 1943, after Italy capitulated, she was taken over by the German Navy and was converted into a transport submarine and was given the new name UIT-22. In Mar 1944, ULTRA decryption efforts led to her journey being discovered by the Allies, and two PBY Catalina aircraft were able to intercept and sank her in the Indian Ocean south of the Cape of Good Hope. All 43 aboard were killed.

Alpino Bagnolini Operational Timeline

1938年12月15日	The keel of Alpino Bagnolini was laid down by Cantieri Navale Tosi di Taranto in Taranto, Italy.
1939年10月28日	Alpino Bagnolini was launched in Taranto, Italy.
1939年12月22日	Alpino Bagnolini was completed in Taranto, Italy.
1940年4月25日	Franco Pittoni was named the commanding officer of Alpino Bagnolini at Taranto, Italy.
1940年6月6日	Alpino Bagnolini departed Taranto, Italy at 0110 hours, starting her first war patrol.
1940年6月12日	Alpino Bagnolini sighted two shadows in the Mediterranean Sea 80 kilometers (50 miles) south of Cape Lithion, Crete, Greece at 0050 hours. At 0056, the commanding officer, Franco Pittoni, determined them to be enemy warships and ordered an attack on the surface. A bow torpedo was fired at 0058 hours, scoring a hit on the starboard side a minute later, and the submarine dove to avoid the expected counterattack. The target was British cruiser HMS Calypso, which sank at 0335 hours. 39 were killed. 139 survivors were picked up by HMS Caledon and 280 survivors were picked up by HMS Dainty, and they were later landed at Alexandria, Egypt.
1940年6月21日	Alpino Bagnolini arrived at Gallipoli, Apulia, Italy, ending her first war patrol. At 1320 hours, she departed Gallipoli and sailed to Taranto, arriving at 1610 hours.
1940年7月5日	Alpino Bagnolini conducted exercises out of Taranto, Italy between 0730 and 1703 hours.
1940年7月9日	Alpino Bagnolini conducted exercises out of Taranto, Italy between 1335 and 1900 hours.
1940年7月10日	Alpino Bagnolini conducted exercises out of Taranto, Italy between 1115 and 1610 hours.

1940年7月12日	Alpino Bagnolini departed Taranto, Italy at 0800 hours, starting her second war patrol.
1940年7月27日	Alpino Bagnolini sighted a submarine off Cape Santa Maria de Leuca, Italy at 0215 hours, but lost contact shortly after. Around the same time, Reginaldo Giuliani also reported a submarine in the same area. Thus, it was possible that the two Italian submarines had sighted each other. At 1200 hours, Alpino Bagnolini arrived at Taranto, Italy at 1200 hours, ending her second war patrol.
1940年8月17日	Alpino Bagnolini departed Taranto, Italy at 0645 hours for exercises, returning at 1230 hours.
1940年8月30日	Alpino Bagnolini departed Taranto, Italy at 0700 hours for exercises, returning at 1120 hours.

1940年9月15日	Alpino Bagnolini sighted a destroyer in the Atlantic about 80 miles west of Cabo de São Vicente, Portugal at 1542 hours; she dove to avoid detection.
1940年9月18日	Alpino Bagnolini sighted a freighter 20 miles west of Porto, Portugal at 1410 hours. She submerged at 1500 hours, approached, and then identified the target as Spanish freighter Cabo Tortosa. Commanding officer Franco Pittoni considered stopping the ship and checking for papers, but the apperance of smoke on the horizon, feared to be Allied warships, led Pittoni to bypass the checking of papers and to attack the freighter. A bow torpedo hit Cabo Tortosa at 1543 hours, and she sank about 1.5 hours later. All aboard survived and were later rescued by Spanish ship Monte Ayala.
1940年9月24日	Alpino Bagnolini sighted a Sunderland aircraft at the distance of 2,000 meters in the Atlantic Ocean. The Italian submarine fired on it with her machine guns and claimed to have hit the aircraft and forced it to turn around.
1940年9月30日	Alpino Bagnolini arrived at Bordeaux, France, ending her third war patrol.
1940年10月24日	Alpino Bagnolini departed Bordeaux, France at 1100 hours, starting her fourth war patrol.

1940年12月8日	Alpino Bagnolini departed Pauillac, Aquitaine, France at 1345 hours, starting her fifth war patrol.
1940年12月19日	Alpino Bagnolini sighted British freighter Amicus in the Atlantic Ocean at 1750 hours and submerged to approach. At 1915 hours, she lost sight of the target, and surfaced in order to regain contact. At 2010 hours, the Italian submarine fired a bow torpedo. At 2011 hours, with the first torpedo still traveling (the target's distance was further than the Italians had estimated), a second bow torpedo was fired. 10 seconds after the launch of the second torpedo, the first one scored a hit, sinking Amicus 20 minutes later. All 36 aboard were lost. HMS Westcott was dispatched to assist survivors, though there would be none. Commanding officer Franco mistakenly reported the name of the victim as Amiens.
1941年1月1日	Alpino Bagnolini sighted an Allied aircraft in the Atlantic Ocean at 1920 hours. 20 minutes later, she fired her machine guns, keeping the aircraft at an distance. The British aircraft dropped a parachute flare, which brought in the nearby armed trawler HMT Northern Pride. At 2045 hours and 2050 hours the Italian submarine detected noises with her hydrophones, and at 2135 hours she heard pings from British ASDIC, which led to commanding officer Franco Pittoni to issue the order to dive. The subsequent depth charge attack caused damage, leading to water leaks at the conning tower hatch and the forward torpedo loading hatch and damage to the gyrocompass. When the electric motors were started, the starboard motor caught on fire. The submarine was forced to surface due to the damage, and the Italians found themselves to be only 200 meters from HMT Northern Pride and two others, HMS Scimitar and HMS Skate. A stern torpedo was fired, but it missed. The Allied warships fired on the submarine at 2037 hours, but the shells passed overhead due to the close distance. Alpino Bagnolini fired two stern torpedoes as she attempted to escape, recording one possible hit, though none of the Allied ships involved in the engagement were damaged. She find a rain squall and the Allied warships lost contact with her.
1941年1月2日	Franco Pittoni of Italian submarine Alpino Bagnolini reported serious damage and requested permission to end his war patrol early.
1941年1月3日	A British Beaufort bomber of No. 217 Squadron RAF flown by Flight Lieutenant A. V. Hunter attacked Italian submarine Alpino Bagnolini with four 250-pound anti-submarine bombs in the Atlantic Ocean between 1900 and 1950 hours.

1943年3月2日	Alpino Bagnolini sighted an aircraft in the Atlantic Ocean at 1140 hours; she submerged to avoid detection.
1943年3月12日	Alpino Bagnolini sighted an aircraft in the Atlantic Ocean at 1900 hours; she submerged to avoid detection.
1943年3月15日	Alpino Bagnolini sighted an aircraft in the Atlantic Ocean at 1022 hours; she submerged to avoid detection. The aircraft, a Pan American Airways Clipper, sighted the submarine and reported the position. At 1430 hours, a Catalina aircraft which responded to the sighting spotted the Italian submarine, but could not attack before losing contact. At 2305 hours, the Italian submarine sighted an aircraft which was operating a search light; she submerged to avoid detection. The aircraft, an American Catalina aircraft piloted by Lieutenant Commander B. J. Prueher of VP-83 squadron, dropped four depth charges on Alpino Bagnolini's position, disabling the submarine's hydrophones.
1943年3月16日	Alpino Bagnolini sighted an aircraft in the Atlantic Ocean at 0410 hours; she submerged to avoid detection. At 0501 hours, she resurfaced. At 0510 hours, after finding herself illuminated by a searchlight, she crash dived. She returned to the surface at 0600 hours, only to be illuminated by multiple searchlights one minute later, and she crash dived again; a megaphone was stuck in the conning tower hatch, preventing it from closing properly, and twenty tons of water entered the submarine. Unable to submerge, she made a successful escape on the surface.

1943年3月22日	Alpino Bagnolini began sailing toward France to end her war patrol. En route, she sighted smoke in the Atlantic Ocean at 1340 hours, and she submerged to attack. She later identified the ship as a British destroyer. Without a working hydrophone, which was damaged from an air attack on 15 Mar 1943, it was difficult to track the target while submerged, and ultimately the target moved too far away from her for her to effectively launch an attack.

1943年4月6日	Alpino Bagnolini sighted an aircraft in the Atlantic Ocean at 1337 hours; she submerged to avoid detection. At 1541 hours, she sighted a periscope, and the Italian submarine turned away. At 1703 hours, she sighted another aircraft, and again submerged.
1943年4月7日	Alpino Bagnolini detected an aircraft with her Metox radar detector in the Atlantic Ocean at 0515 hours; she submerged to avoid detection.
1943年4月10日	Alpino Bagnolini surfaced in the Atlantic Ocean at 1430 hours for radio communications. At 1630 hours, four explosions were heard to the port side, followed by four explosion on the starboard side. Submerging, her crew would soon realize that the intended target was another submarine, and the attacks would continue for some time. She surfaced at 2223 hours, and sighted an aircraft four minutes later; she submerged to avoid detection.
1943年4月11日	Alpino Bagnolini sighted an aircraft in the Atlantic Ocean at 0501 hours; she submerged to avoid detection. At 1025 hours, she sighted a periscope and turned away.

1943年4月13日	Alpino Bagnolini sighted a ship in the Atlantic Ocean at 0357 hours and another at 0455, neither of which responded to her recognition signals; given her distance to the French coast, the Italian submarine assumed them to be friendly. At 1448 hours, she arrived at Bordeaux, France, ending her tenth war patrol.
1943年5月22日	Ferdinando Corsi was named the commanding officer of Alpino Bagnolini at Bordeaux, France; he replaced Angelo Amendolia.

UIT-22 was on her first patrol since the German takeover. According to records made available, this South African squadron was sent to the attack area after detailed instructions about the rendezvous point in the Indian Ocean had been deciphered. All 43 aboard the German submarine were killed
