''C29'' served in the [[First World War]] until she was sunk by mine on 29 August 1915.

==Design and description== The C-class boats of the 1907–08 and subsequent Naval Programmes were modified to improve their speed, both above and below the surface. The submarine had a length of {{convert|142|ft|3|in|m|1}} [[length overall|overall]], a [[beam (nautical)|beam]] of {{convert|13|ft|7|in|m|1}} and a mean [[draft (ship)|draft]] of {{convert|11|ft|6|in|m|1}}. They [[displacement (ship)|displaced]] {{convert|290|LT|t}} on the surface and {{convert|320|LT|t}} submerged. The C-class submarines had a crew of two officers and fourteen [[naval rating|ratings]].<ref name=gg9>Gardiner & Gray, p. 87</ref>

For surface running, the boats were powered by a single 12-cylinder<ref>Harrison, Chapter 25</ref> {{convert|600|bhp|lk=in|0|adj=on}} [[Vickers]] [[petrol engine]] that drove one [[propeller shaft]]. When submerged the propeller was driven by a {{convert|300|hp|0|adj=on}} [[electric motor]].<ref name=gg9/> They could reach {{convert|13|kn|lk=in}} on the surface and {{convert|8|kn}} underwater. On the surface, the C class had a range of {{convert|910|nmi|lk=in}} at {{convert|12|kn}}.<ref>Harrison, Chapters 3</ref>

The boats were armed with two [[British 18 inch torpedo|18-inch (45 cm)]] [[torpedo tube]]s in the bow. They could carry a pair of reload torpedoes, but generally did not as they would have to remove an equal weight of fuel in compensation.<ref>Harrison, Chapter 27</ref>

==Construction and career== HMS ''C29'' was built by [[Vickers]], [[Barrow-in-Furness|Barrow]]. She was laid down on 4 June 1908 and was commissioned on 17 September 1909. The boat sank a [[merchant ship]] while patrolling the [[Gulf of Riga]] in the [[Baltic Sea|Baltic]].

''C29'' was involved in the use of 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 while attempting to employ the tactic; she was [[Naval mine|mined]] when her trawler ''Ariadne'' strayed into a minefield in the [[Humber Estuary]] on 29 August 1915.<ref name=britsubs>{{cite book|last=Kemp|first=Paul J.|title=British Submarines of World War One|year=1990|publisher=Arms and Armour Press|location=London|isbn=9781854090102|page=8}}</ref>
