**HMS *C29*** was one of 38 [C-class submarines](/source/British_C-class_submarine) built for the [Royal Navy](/source/Royal_Navy) in the first decade of the 20th century. *C29* served in the [First World War](/source/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 142 feet 3 inches (43.4 m) [overall](/source/Length_overall), a [beam](/source/Beam_(nautical)) of 13 feet 7 inches (4.1 m) and a mean [draft](/source/Draft_(ship)) of 11 feet 6 inches (3.5 m). They [displaced](/source/Displacement_(ship)) 290 long tons (290 t) on the surface and 320 long tons (330 t) submerged. The C-class submarines had a crew of two officers and fourteen [ratings](/source/Naval_rating).[1]

For surface running, the boats were powered by a single 12-cylinder[2] 600-[brake-horsepower](/source/Horsepower#Brake_horsepower) (447 kW) [Vickers](/source/Vickers) [petrol engine](/source/Petrol_engine) that drove one [propeller shaft](/source/Propeller_shaft). When submerged the propeller was driven by a 300-horsepower (224 kW) [electric motor](/source/Electric_motor).[1] They could reach 13 [knots](/source/Knot_(unit)) (24 km/h; 15 mph) on the surface and 8 knots (15 km/h; 9.2 mph) underwater. On the surface, the C class had a range of 910 [nautical miles](/source/Nautical_mile) (1,690 km; 1,050 mi) at 12 knots (22 km/h; 14 mph).[3]

The boats were armed with two [18-inch (45 cm)](/source/British_18_inch_torpedo) [torpedo tubes](/source/Torpedo_tube) 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.[4]

## Construction and career

HMS *C29* was built by [Vickers](/source/Vickers), [Barrow](/source/Barrow-in-Furness). She was laid down on 4 June 1908 and was commissioned on 17 September 1909. The boat sank a [merchant ship](/source/Merchant_ship) while patrolling the [Gulf of Riga](/source/Gulf_of_Riga) in the [Baltic](/source/Baltic_Sea).

*C29* was involved in the use of the [U-boat](/source/U-boat) trap tactic. The tactic was to use a decoy trawler to tow a [submarine](/source/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 [mined](/source/Naval_mine) when her trawler *Ariadne* strayed into a minefield in the [Humber Estuary](/source/Humber_Estuary) on 29 August 1915.[5]
