First patrol

U-218 departed Kiel on her first patrol on 28 August 1942. She moved 'up' the length of the North Sea, through the gap separating Iceland and the Faroe Islands and into the Atlantic Ocean, heading south-west. She damaged Fjordaas in mid-ocean on 11 September. An inspection by the vessel's Master, 1st Mate and Chief Engineer preceded her recovery to the Clyde where she was repaired and returned to service in December 1942.

The escorts of Convoy ON 127 damaged the boat the following day so severely she was obliged to abort the patrol and head for occupied France.

U-218 docked at Brest on 29 September.

Second patrol

Her luck did not improve on her second foray. The submarine was attacked from the air and by surface ships south-west of Portugal on 15 November 1942. The damage inflicted was bad enough to force her to return to Brest on the 25th.

Third and fourth patrols

U-218's third and fourth efforts were in early and mid-summer 1943. They were relatively uneventful.

Fifth patrol

The routine of the boat's fifth sortie was rudely interrupted on 2 August 1943 by an attack by a Vickers Wellington of No. 547 Squadron RAF west of the Bay of Biscay. Six crewmen were wounded, the submarine was severely damaged and once again an early return was required.

Sixth and seventh patrols

Patrol number six was marked by two men falling overboard in heavy weather on 27 September 1943 – they were both picked up 45 minutes later. A month later the boat laid mines near Port of Spain, Trinidad on 27 October.

U-218 had a rare triumph on 5 November when she sank the sailing ship Beatrice Beck east of Martinique with her cargo of cod.

The boat departed Brest for what became her seventh and longest patrol (86 days) on 12 February 1944. She did not return until 7 May. Nevertheless, the waters east of the West Indies were unproductive.

Eighth patrol

The boat was hunted 'mercilessly' for sixty hours from 15 June 1944; she eventually shook off her attackers. She damaged the auxiliary cruiser HMS Empire Halberd on 6 July with a mine laid on the second off Lands End (south-west England). The ship was taken, first to Falmouth, then Glasgow for repairs. She returned to service in late 1944 as HMS Silvio. Meanwhile, the U-boat returned to Brest on 10 July.

Ninth and tenth patrols

Having departed Brest for the last time on 10 August 1944, U-218 laid mines near Lizard Head (Cornwall), before retracing her course west of Ireland. She arrived in Bergen, Norway on 23 September. There now followed a series of short journeys between October 1944 and March 1945.

The boat's tenth and final patrol began with her departure from Bergen on 22 March 1945. She sank the Ethel Crawford on 20 April with a mine laid on the 18th in the Firth of Clyde.

Fate

U-218 surrendered in Bergen on 12 May 1945. She was transferred to Loch Ryan in Scotland in anticipation of Operation Deadlight. She sank while under tow to the scuttling grounds about eight or nine nautical miles north of Inishtrahull (the most northerly island of Ireland) on 4 December.^[4]

Afterword

U-218 was also thought to be responsible for sinking the last British ship to be sunk as the result of World War II. The steam fishing vessel Kurd was sunk on 10 July 1945 after hitting a British mine off Lizard Head^[5][6]

The wreck of the U-boat was identified by marine archaeologist Innes McCartney in 2001 off Malin Head.

Wolfpacks

U-218 took part in seven wolfpacks, namely:

• Vorwärts (4 – 15 September 1942)
• Natter (2 – 8 November 1942)
• Westwall (8 – 15 November 1942)
• Rochen (27 January – 25 February 1943)
• Naab (12 – 15 May 1943)
• Donau 2 (15 – 19 May 1943)
• Mosel (19 – 24 May 1943)
