 07-01-1940   HMS Undine was on her fourth war patrol in January 1940 when her asdic failed due to a leak. At 0940 on 7th January, Undine sighted what was thought to be three trawlers 20 miles west of Heligoland; but were in fact German minesweepers.

Undine unsuccessfully attacked the leading vessel; minutes later there was a large explosion followed by others as the minesweepers opened fire. Undine was at 50 feet and proceeding blind due to the loss of asdic.

After 5 minutes of no further attacks Undine raised her periscope as she did so an explosion shook the submarine, blowing her upwards and rendering the hydroplanes useless. Without the use of the hydroplanes escape would have been impossible and the order to abandon ship was given.

Whilst the crew entered the water, to be picked up by the minesweepers, demolition charges were set and the submarine scuttled.
