HMS C29

HMS C29 was a British C class submarine built by Vickers, Barrow. She was laid down on 4 June 1908 and was commissioned on 17 September 1909.

Service history
C29 sank a merchant ship while patrolling the Gulf of Riga in the Baltic.

C29 was involved in the U-boat trap tactic. 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.

C29 was one of the two C class submarines sunk because of the tactic. She was mined when her trawler Ariadne strayed into a minefield in the Humber Estuary on 29 August 1915.
