HMS Undine was a U-class submarine and lead vessel of her class, which is sometimes called the Undine class as a result. The submarine entered service in 1938. Undine performed war patrols during the Second World War and was scuttled after being damaged by German minesweepers off Heligoland on 7 January 1940.
Construction and career
Undine was on her fourth war patrol in January 1940 when her sonar failed due to a leak. At 0940 on 7 January, she sighted what was thought to be three trawlers 20 miles (32 km) west of Heligoland; but were in fact the German auxiliary minesweepers M-1201, M-1204 and M-1207. She unsuccessfully attacked the leading vessel, but the minesweepers counter attacked and forced her to dive. Undine was at 50 feet (15 m) and proceeding blind due to the loss of sonar. After five minutes with no further attacks, she 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, Undine was scuttled.
