HMS Thistle (N24) was a T-class submarine of the Royal Navy. She was laid down by Vickers Armstrong, Barrow and launched in October 1939. She was sunk by the German submarine U-4 on 10 April 1940 near Skudenes.
Thistle, under the command of Lt. Wilfrid Frederick Haselfoot, was ordered to patrol off Stavanger, and to sink any enemy vessel that she might spot in the harbour, since British authorities believed that a German invasion of Norway was imminent. On 10 April Thistle signaled her intention to comply with this order and that she had two torpedoes remaining after an unsuccessful attack on a U-boat. With this in mind the Admiralty changed her orders to patrol off Skudenes. No further contact was made with Thistle.
The action began when HMS Thistle spotted U-4 cruising on the surface with a periscope. At 16.04 hours on 9 April 1940 HMS Thistle fired a spread of six torpedoes, all of which missed. HMS Thistle later reported the unsuccessful engagement via radio, and that the submarine had only two torpedoes left.
U-4 observed one torpedo passing ten meters ahead and evaded further underwater attacks by crash diving. The U-boat crew later heard three explosions of the off-track torpedoes at the end of their run. Afterwards U-4 found HMS Thistle on the surface recharging its batteries.
At 02.13 hours on the morning of 10 April 1940, U-4 fired a spread of two torpedoes at its attacker. The first, a G7a torpedo, missed. The second, a G7es torpedo, found its mark, sinking Thistle with all hands near Skudenes.
