HMS C24

HMS C24 was a British C class submarine built by Vickers, Barrow. She was laid down on 12 February 1908 and was commissioned on 5 May 1909.

Service history
HMS C24 was used in the first successful U-boat trap. She operated with the decoy trawler Taranaki. They were able to sink SM U-40 25 mi off Eyemouth in the North Sea on 23 June 1915.

The tactic was to use a decoy trawler to tow a submarine. When a U-boat was sighted, the tow line and communication line was slipped and the submarine would attack the U-boat. The tactic was partly successful, but was abandoned after the loss of two C class submarines. In both cases, all the crew were lost.

HMS C24 was sold on 29 May 1921 in Sunderland.
