Design, construction, and trials[edit | edit source]
U-36 was laid down on 2 January 1913 at Germaniawerft in Kiel. She was launched on 6 June 1914 and commissioned on 14 November 1914, under the command of Kplt. Ernst Graeff. During February 1915, she carried out acceptance trials at Kiel, and was attached to the 2d Half-Flotilla in the North Sea in March.
Service career[edit | edit source]
SM U-36's movements and operations were monitored and reported by British Naval Intelligence, better known as "Room 40". Her first war patrol was in Heligoland Bight from 29 to 30 March 1915; she reported no sinkings during this time. On 23 April, she returned to Heligoland Bight, apparently from a North Sea patrol.[Note 1]
She departed on 29 April, bound again for the North Sea, where she sank the 1,966 ton Danish steamer Lilian Drost on 8 May, captured the 1,241 ton Swedish steamer Björn on 10 May as a prize, while capturing and releasing the 654 ton Dutch steamer Niobe the same day.
U-36 returned to her North Sea station on 17 July. Operating off the north and northwest coast of Scotland, she sank three steamers and almost a dozen smaller vessels. On 22 July, the 3,644 ton Russian Rubonia fell victim. That same day, U-36 also attacked a group of fishing vessels west of the Orkney Islands, sinking nine small trawlers and two sailing vessels, while taking one prize. The following day, the 1,505 ton Frenchman Danae was stopped according to prize rules and sunk, and the 3,819 ton Norwegian Fimreite was sunk as well.
On the day she was sunk, U-36 intercepted and captured the American windjammer Pass of Balmaha, bearing a cargo of cotton intended for Russia and en route to Kirkwall to be inspected by British authorities. An ensign from U-36 was left aboard the windjammer to ensure her successful passage to Cuxhaven. The Pass was refitted as a merchant raider and re-christened Seeadler, commanded by Count Felix von Luckner, soon to become famous for her naval exploits in the Atlantic and Pacific.
Fate[edit | edit source]
U-36 was sunk in the afternoon of 24 July 1915 in combat off the coast of North Rona in the Outer Hebrides with the British Q-ship[Note 2] Prince Charles, commanded by Lieutenant Mark Wardlaw, Royal Navy. The submarine had just stopped and boarded the Danish vessel SS Luise and a boarding party was in the process of dumping her cargo when a lookout sighted an approaching steamer. U 36 sailed towards the disguised Prince Charles and ordered her to stop while firing at her. The Q-ship complied, swinging out her boats. The unsuspecting submarine came within about 600 m (660 yd) of the ship when Prince Charles hoisted the British flag of war and commenced firing. Taken completely by surprise, U-36 took several direct hits and heavy damage, and sank. When Luise moved to pick up the survivors floating in the water, Prince Charles fired into her, believing her to be a German resupply vessel. Forty-five minutes after U-36 sank, the remaining survivors were picked up by the Q-ship. Kplt. Graeff and 15 crewmen were saved, but 18 others were lost. U-36 was the first U-boat sunk by Q-ship, and one of only a handful to fall victim. Lieutenant Wardlaw received a Distinguished Service Order for the action, and two of his crew received Distinguished Service Medals. The merchant crew of the Q-ship was awarded a prize sum of £1,000, to be divided amongst themselves.
