During the Norwegian Campaign, SEAL (Lt Cdr R P Lonsdale) arrived off Goteborg and Vinga in the Kattegat to lay mines in 57-33.5N, 11-35.5E.  Shortly after completing the lay at 0859, SEAL struck a mine herself and was badly damaged. In this state, she was captured early on 5 May by two German Arado seaplanes of the German Navy and towed to Frederikshavn by  trawler UJ.128 (trawler FRANKEN, 435 tons) of the 12th Anti-submarine Flotilla.

Lt Cdr Lonsdale, Lt T B J D Butler, Lt T A Beet, Lt (E) R H S Clark, S/Lt A R L  Henderson, S/Lt R W H Boulnois and 48 ratings were taken prisoner. One rating was lost with the submarine and another died while a prisoner of war.

Preliminary repairs were made to SEAL at Frederikshaven by the 9th May and on the 10th, she left under tow for Kiel where she arrived on 11 May. SEAL was commissioned as German U.B on 30 November 1940.

Four ships were lost on SEAL'S FD 7 minefield.
