U-31 was attached to the U-Flottille Saltzwedel then to the famed
2nd U-Bootflottille. She patrolled the North
Atlantic and the North Sea in September and December 1939, had a minelaying
mission off Loch Ewe in the North Minch on 27 October 1939 and again on 21
January 1940. She was sunk on 11 March 1940 by RAF aircraft with all hands
plus 13 other naval personnel lost.
U-31 was raised and recommissioned on 30 July 1940 when she began
her second life, again attached to the 2nd U-Bootflottille. On her first
Feindfahrt (war patrol) she had an engagement with a British submarine on 8
October 1940 with no outcome. She was sunk the second time on 3 November
1940 by HMS ANTELOPE (H-36) with four men lost and all others
captured.
U-31 was the first submarine to attack a convoy in World War Two
and she was the first submarine in that war to be sunk twice.

BACK TO U-BOAT HISTORY PAGE
Many thanks to our friend and Sharkhunters Member since
1987 GEORG HÖGEL for all the conning tower emblems used in our monthly
KTB Magazine and also here on the pages of our website. GEORG
was radioman aboard U-30, the first boat into combat, the first to
sink a ship (the liner ATHENIA) and the first into an occupied
French port. When that Skipper (Lemp) took command of U-110,
GEORG was one of the former crew to transfer to the new boat under Lemp.
After the war, he was Professor of Art at a major German university.
