Editing German submarine U-110 (1940) (section)

==Operational career==

===First patrol===
''U-110'' set out on her first patrol from [[Kiel]] on 9 March 1941. Her route to the Atlantic Ocean took her through the [[GIUK gap|gap]] between the [[Faroe Islands|Faroe]] and [[Shetland Islands]]. Her first victim was ''Erodona'' which she damaged south of [[Iceland]] on 16 March. She also damaged ''Siremalm'' on the 23rd. This ship only escaped after she was hit by a [[torpedo]] which failed to detonate, (although it left a large dent) and the U-boat's 105&nbsp;mm [[deck gun]] crew forgot to remove the [[tampion]] in the muzzle before engaging their target. The resulting explosion on firing the first round wounded three men and compelled the boat to fire on the merchantman with the smaller 37 and 20&nbsp;mm armament. Despite being hit, ''Siremalm'' successfully fled the scene, zig-zagging as she went.

''U-110'' arrived in Lorient on the French Atlantic coast on 29 March, having cut the patrol short due to damage from the exploding gun.

===Second patrol and capture===
The boat departed Lorient on 15 April 1941. On the 27th, she sank ''Henri Mory'' about {{convert|330|nmi}} west northwest of [[Blasket Islands]], Ireland.

Her next quarry were the ships of [[convoy OB 318]] east of [[Cape Farewell, Greenland|Cape Farewell]] (Greenland). She successfully attacked and sank ''Esmond'' and ''Bengore Head'', but the escort vessels responded. The British corvette {{HMS|Aubrietia|K96|6}} located the U-boat with [[ASDIC]] (sonar). ''Aubrietia'' and British destroyer {{HMS|Broadway|H90|2}} then proceeded to drop [[depth charge]]s, forcing ''U-110'' to surface.<ref>{{cite web |url=http://www.uboatarchive.net/U-110A/U-110GreenockReportU-110.htm|title=U-boat Archive – U-110 – Greenock Report – Attacks on U-110|access-date=3 October 2014}}</ref>

===Operation ''Primrose'' (9 May 1941)===

''U-110'' survived the attack, but was seriously damaged. {{HMS|Bulldog|H91|6}} and ''Broadway'' remained in contact after ''Aubrietia''{{'}}s last attack. ''Broadway'' shaped course to ram, but fired two depth charges beneath the U-boat instead, in an endeavour to make the crew abandon ship before scuttling her.<ref>{{cite web |url=http://www.uboatarchive.net/U-110A/U-110GreenockReport.htm|title=U-boat Archive – U-110 – Greenock Report – Attacks on U-110|access-date=3 October 2014}}</ref> Lemp announced "Last stop, everybody out", meaning "Abandon ship". As the crew turned out onto the U-boat's deck they came under fire from ''Bulldog'' and ''Broadway'' with casualties from gunfire and drowning. The British had believed that the German deck gun was to be used and ceased fire when they realised that the U-boat was being abandoned and the crew wanted to surrender.

Lemp realised that ''U-110'' was not sinking and attempted to swim back to it to destroy the secret material, and was never seen again. A German eyewitness testified that he was shot in the water by a British sailor, but his fate is not confirmed. Including Lemp, 15 men were killed in the action, and 32 were captured. Radio Officer Georg Högel and the rest of the crew were held at ''Camp 23'' ([[Monteith POW camp]] at [[Iroquois Falls, Northern Ontario]], Canada), which is now the [[Monteith Correctional Complex]].

''Bulldog''{{'}}s [[boarding (attack)|boarding]] party, led by Sub-Lieutenant David Balme, got onto ''U-110'' and stripped it of everything portable, including her [[Kurzsignale]] code book and [[Enigma machine]].<ref>{{cite web|url=http://news.bbc.co.uk/2/hi/uk_news/774427.stm|title=Capturing the real ''U-571'', BBC|access-date=3 October 2014}}</ref> William Stewart Pollock, a former radio operator in the Royal Navy and on loan to ''Bulldog'', was on the second boat to board ''U-110''. He retrieved the Enigma machine and books as they looked out of place in the radio room. ''U-110'' was taken in tow back toward Britain, but was intentionally sunk en route to prevent its capture from being revealed.

The documents captured from ''U-110'' helped [[Bletchley Park]] codebreakers solve ''[[Reservehandverfahren]]'', a reserve German hand cipher.<!-- and more...-->
