German submarine U-527
German submarine "U-527" was a Type IXC U-boat of Nazi Germany's "Kriegsmarine" during World War II. She was laid down at the Deutsche Werft yard in Hamburg as yard number 342 on 28 October 1941, launched on 17 June 1942 and commissioned on 2 September with "Kapitänleutnant" Herbert Uhlig in command. "U-527" began her service career with training as part of the 4th U-boat Flotilla from 2 September 1942. She was reassigned to the 10th flotilla for operations on 1 February 1943. She carried out two patrols and sank one ship. She also sank  one warship and damaged one commercial vessel. She was a member of four wolfpacks. She was sunk by US aircraft south of the Azores on 23 July 1943. Design. German Type IXC/40 submarines were slightly larger than the original Type IXCs. "U-527" had a displacement of when at the surface and while submerged. The U-boat had a total length of , a pressure hull length of , a beam of , a height of , and a draught of . The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of for use  while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of for use while submerged. She had two shafts and two propellers. The boat was capable of operating at depths of up to . The submarine had a maximum surface speed of and a maximum submerged speed of . When submerged, the boat could operate for at ; when surfaced, she could travel at . "U-527" was fitted with six torpedo tubes (four fitted at the bow and two at the stern), 22 torpedoes, one SK C/32 naval gun, 180 rounds, and a SK C/30 as well as a  C/30 anti-aircraft gun. The boat had a complement of forty-eight. Service history. First patrol. The boat departed Kiel on 9 February 1943, moved through the North Sea, negotiated the gap between Iceland and the Faroe Islands and entered the Atlantic Ocean. There, southeast of Cape Farewell (Greenland), she sank "Fort Lamy" on 8 March. HMS "LCT-2480" was also lost. She damaged "Mathew Luckenbach" on 19 March. came across the drifting wreck and finished her off. "U-527" was attacked by a Sunderland flying boat on the 20th - damage was slight. She entered Lorient, on the French Atlantic coast, on  12 April 1943. Second patrol and loss. Having left Lorient on 10 May 1943, she was in the middle of "attacking a large ship under tow, when a corvette was summoned, which dropped 15 depth charges", damage sustained was minimal. Her sortie continued as far as the Gulf of Mexico. On the return leg, on 23 July 1943, she was sunk south of the Azores by Avenger aircraft from the carrier . Pilot : Robert L Stearns from "Bogue" dropped four shallow-set depth charges as "U-527" made for cover in a bank of sea fog. The pressure hull aft was blown  open, "U-527" sank instantly. Forty men went down with the U-boat; there were 13 survivors. One survivor died in the water of internal injuries. Twelve survivors, sharing four punctured life-vests, were picked up after considerable time in the water; by and then later transferred to USS "Bogue". The survivors recall having deafness and contusions which took two weeks to recover from. The survivors were taken to Casablanca and put in the prison there for full interrogation. They were later transported to the USA. The crew had a considerably high regard and respect for their captain, Captain Uhlig, aged  27 years finding him a man of great integrity and fairness. The crew recall that, quite the opposite to the film, 'Das Boot', that they only ever spoke in orderly, quiet voices during service on the seas and that they were neither allowed to shout nor would have done so. On "U-527" being hit by the depth charges from the Avenger Aircraft there was only time for the twelve men on watch to escape and one other who was not on watch but around the conning tower. By an act of extreme bravery, Captain Herbert Uhlig, on finding the hatch  exit from the conning tower to be damaged and unable to be opened normally, "put his shoulder to the hatch and exerted his utmost force" and the hatch came open. Family of Captain Uhlig remember his having a shoulder injury and weakness for the rest of his life to that shoulder. This act saved the lives of those few of the crew who had time and proximity to escape as "U-527" sank almost immediately. Others closer to the blast and damage would have died instantly, the survivors recalled. The crew were kept together when they arrived in the United States  and were put to work in Arizona picking cotton, grapefruit, pineapples and working at the Biltmore Hotel golf course as green keepers. One member of the crew gave away more information than they had been briefed to allow, at Kriegsmarine Schule in their training in Kiel, and he was summarily executed by other German POW's in their POW camp. This caused great sadness, depression and fear amongst those not involved. In 1945 at the cessation of hostilities the crew along with other naval POW's were transported by ship on the assumption that they were being re-patriated to  Germany. After they had passed through the Panama Canal and entered the Atlantic, as mariners they realised quite early that they were not on a course to 'home' but to Britain. They were taken to Liverpool to contribute towards reparation and put to work on farms as laborers to make up for the casualties who failed to return to farm work in Britain because of the war years. They were held as POWs for up to four more years in the UK, before being given new suits and shoes and travel permits to return to their homes. One survivor decided  to return to Britain to marry a Yorkshire farmer's daughter. The crew stayed in touch with each other and often, in later years, made a point of returning to the Kriegsmarine Memorial in Kiel, with their families, each year on 23 July. Many of the remaining crew survived until old age, the last passing away in 2012. Wolfpacks. "U-527" took part in four wolfpacks, namely:
