German submarine U-108 was a Type IXB U-boat of Nazi Germany's Kriegsmarine that operated during World War II. She was laid down at DeSchiMAG AG Weser in Bremen as yard number 971 on 27 December 1938, launched on 15 July 1940 and commissioned on 22 October under Korvettenkapitän Klaus Scholtz.
1st, 2nd and 3rd patrols
The boat's first patrol began with her departure from Wilhelmshaven on 15 February 1941. She crossed the North Sea and entered the Atlantic via the gap between Iceland and the Faroe Islands, sinking Texelstroom on 22 February. She also sank Effna on the 28th; both ships met their end south of Iceland. She then docked at Lorient in occupied France on 12 March. She would be based there for most of the rest of her career.
U-108 sank Michael E., a CAM ship or 'Catapult Armed Merchantman', on the submarine's third patrol on 2 June 1941 in mid-Atlantic. She went on to sink Baron Nairn west of Cape Race (eastern Newfoundland and Labrador) on the 8th; the Greek ship Dirphys 600 nautical miles (1,100 km; 690 mi) east of Newfoundland, also on 8 July; Christian Krohg on the 10th; Ellinco on the 25th; Nicholas Pateras on the same day and Toronto on 1 July. The latter was a weather ship situated about 500 nmi (930 km; 580 mi) north of the Azores.
4th, 5th and 6th patrols
Patrol number four saw the boat covering the 'gap' between South America and Africa. She departed Lorient on 19 August 1941 and returned on 21 October.
She sank Cassequel, a neutral vessel, on 14 December 1941, 160 nmi (300 km; 180 mi) southwest of Cape St. Vincent, Portugal and Ruckinge (convoy HG 76) on the 19th, west of Lisbon as part of her fifth sortie.
The boat's sixth patrol, as part of Operation Drumbeat (Paukenschlag), took her to the east coast of North America where she was again successful, sinking Ocean Venture on 8 February 1942, Tolosa on the 9th and Blink on the 12th. The U-boat had chased Blink, which had been hit by a non-detonating torpedo, the two vessels almost collided; which was only avoided by U-108 diving underneath the merchant ship.
She also sank Ramapo northwest of Bermuda on 16 February and Somme on the 18th.
7th, 8th and 9th patrols
The boat's seventh patrol was almost as successful as her sixth, sinking Modesta on 25 April 1942, Mobiloil on the 29th (which required a total of six torpedoes and many rounds from the 20mm and 37mm guns), Afoundria on 5 May, and Abgara a day later. On the return leg she encountered Norland on the 25th.
More success pennants were flown after her eighth patrol, which took her almost to the northern South American coast. She sank Tricula on 3 August 1942, Breňas on the 7th and Louisiana on the 17th.
The boat's ninth patrol was carried out in opposition to Operation Torch, (the Allied landings in North Africa). The submarine had not been off Morocco long before being attacked by a destroyer. The damage incurred was serious enough that the boat was obliged to return to France where effective repairs might be carried out.
10th and 11th patrols
In her last operational patrol, she departed Lorient on 1 April 1943. She was attacked by a destroyer on the 22nd but continued to shadow Convoy ON (S) 4 southeast of Greenland. She arrived at Stettin in modern-day Poland on 16 May. Bombed and sunk there 11 April, raised and decommissioned 17 July 1944. Scuttled there 24 April 1945.
U-108 took part in seven wolfpacks, namely.
- West (2–20 June 1941)
- Seeräuber (14–22 December 1941)
- Schlagetot (9–17 November 1942)
- Rochen (28 January - 11 February 1943)
- Adler (7–13 April 1943)
- Meise (13–27 April 1943)
- Specht (27–28 April 1943)
