HMS Limbourne (L57)

HMS Limbourne (L57) was a escort destroyer, operated by the Royal Navy. She was sunk in action, off German occupied Guernsey, on October 23, 1943.

Design
Limbourne was one of seven Type III Hunt-class destroyers ordered for the Royal Navy on 4 July 1940, as part of the 1940 War Emergency Programme. The Hunt class was meant to fill the Royal Navy's need for a large number of small destroyer-type vessels capable of both convoy escort and operations with the fleet. The Type III Hunts differed from the previous Type II ships in replacing a twin 4-inch gun mount by two torpedo tubes to improve their ability to operate as destroyers.

The Type III Hunts were 264 ft long between perpendiculars and 280 ft overall, with a beam was 31 ft and draught 7 ft. Displacement was 1050 LT standard and 1490 LT under full load. Two Admiralty boilers raising steam at 300 psi and 620 F fed Parsons single-reduction geared steam turbines that drove two propeller shafts, generating 19000 shp at 380 rpm. This gave a design maximum speed of 27 kn. 345 LT of oil fuel were carried, giving a range of 3700 nmi at 15 kn.

Main gun armament was four 4 inch (102 mm) QF Mk XVI dual purpose (anti-ship and anti-aircraft) guns in two twin mounts, with a quadruple 2-pounder "pom-pom" and three Oerlikon 20 mm cannon providing close-in anti-aircraft fire. Two 21 in torpedo tubes were fitted in a single twin mount, while two depth charge chutes, four depth charge throwers and 70 depth charges comprised the ship's anti-submarine armament. Type 291 and Type 285 radars were fitted, as was Type 128 sonar.

Construction and service
Limbourne was laid down at Alexander Stephen and Sons' shipyard at Linthouse, Glasgow on 8 April 1941. She was launched on 12 May 1942, and was completed on 24 October 1942.

After commissioning, Limbourne spent November in sea trials and work up with the Home Fleet at Scapa Flow, interrupting work up to escort the battleship HMS Howe (32) out to Gibraltar and the aircraft carrier HMS Victorious (R38) and battleship HMS Duke of York (17) back to the UK from the Mediterranean Sea following the Anglo-American landings in North Africa. After completing workup, she joined the 15th Destroyer Flotilla based at Devonport.

January and February she was employed as an escort to convoys between the UK and Gibraltar. During the rest of her operational life she helped patrol the Western Approaches and the Bay of Biscay.

Loss
On 23 October Limbourne was sailing with the light cruiser HMS Charybdis (88) and five other destroyers, when they were engaged by a number of large German Type 39 torpedo boats. Both ships were hit by torpedoes. GERMAN TORPEDO BOAT T22 scored a hit on Limbourne exploding the forward magazine. 40 crewmembers of Limbourne were killed. Attempts were made to tow her back to port, for repairs. The tow attempts had to be abandoned, and she was scuttled.

In 2011 the BBC News reported that "The incident was used as an illustration of what not to do by the Royal Navy tactical school." They reported that the Royal Navy ships were sunk by a smaller but better trained German force.
