SM U-68 was a
commissioned
in August.
Six days into her first war patrol, on 22 March 1916, U-68 was sunk by Farnborough, a British Q-ship, with all hands. U-68 sank no ships in her brief career. A post-war German study found fault with U-68's captain for not following established procedures for avoiding decoy ships.
Design and construction
After the
Germaniawerft 506d design, also known as the Type UD, for its new U-7 class of five submarines.[5] The Navy ordered five boats on 1 February 1913.[6]
The U-7 class was seen by the Austro-Hungarian Navy as an improved version of its
metric horsepower (2,269 bhp; 1,692 kW) total) for surface running at up to 17 knots (31 km/h; 20 mph), and twin electric motors (1,240 PS (1,220 shp; 910 kW) total) for a maximum of 11 knots (20 km/h; 13 mph) when submerged.[6] The boats were designed with five 45 cm (17.7 in) torpedo tubes; four located in the bow, one in the stern. The boats' armament was to also include a single 6.6 cm (2.6 in) L/26 deck gun.[6]
U-9 was
sister boats were complete when World War I began in August 1914.[7] With the boats under construction at Kiel, the Austrians became convinced that it would be impossible to take delivery of the boats, which would need to be towed into the Mediterranean past Gibraltar, a British territory.[6][Note 2] As a result, U-9 and her four sisters were sold to the Imperial German Navy on 28 November 1914.[2][Note 3]
U-9 was renumbered by the Germans as U-68 when her class was redesignated as the Type U 66. The Imperial German Navy had the submarines redesigned and reconstructed to German standards, which increased the surface displacement by 96 tonnes (94 long tons) and the submerged by 48 tonnes (47 long tons). The torpedo load was increased by a third, from 9 to 12, and the deck gun was upgraded from the 6.6 cm (2.6 in) gun originally specified to an 8.8 cm (3.5 in) SK L/30 one.[2]
Service career
U-68 was
commissioned into the Imperial German Navy under the command of Kapitänleutnant Ludwig Güntzel,[1] a new submarine commander.[8] On 29 November, U-68 was assigned to the IV. U-Halbflotille.[9]
U-68 departed the
Gordon Campbell. At approximately 07:00, U-68 fired a torpedo at Farnborough and narrowly missed the ship's bow. Farnborough continued the deception and continued on at her same speed and course. At 07:20, U-68 surfaced about 1,000 yards (910 m) astern of Farnborough, moved to the ship's port quarter, and fired a shot across the Q-ship's bow.[8]
Farnborough stopped, blew off steam, and launched a boat to simulate a surrender. As U-68 closed to 800 yards (730 m), Farnborough raised the
12 pounder (76 mm) guns. The British gunners scored several hits on the U-boat out of 21 rapidly fired rounds. As U-68 began to sink, Campbell steered Farnborough over U-68's location and dropped a depth charge that blew the bow of the submarine out of the water. As U-68 began going down by the stern, Farnborough's gunners scored another five hits on the U-boat's conning tower. U-68 sank with the loss of all 38 men at position 51°54′N 10°53′W / 51.900°N 10.883°W off Dingle in southern Ireland.[8] U-68 sank no ships during her brief service career.[10]
A post-war German study faulted U-68's commander, Kptlt. Güntzel, for failing to follow established procedures for dealing with neutral-flagged vessels in order to avoid decoy ships like Farnborough. According to the report, Güntzel had broken almost all the rules when approaching Farnborough. However, Kommodore Hermann Bauer, the commander of the German High Seas Fleet U-boats, in his post-war memoirs, reports Güntzel was an inexperienced captain and had not, contrary to usual practice, been first sent to sea under a more experienced U-boat captain to gain knowledge.[8]
Notes
- U-3-classsubmarines, however, were less than half the displacement and nearly 90 feet (27 m) shorter than the U-7 design. See: Gardiner, pp. 342–43.
