Quorn was built by J. Samuel White and Co. at Cowes, Isle of Wight. A Type 1 Hunt-class destroyer, she was launched on 27 March 1940 and completed on 21 September 1940 with the pennant number L66.[2] She was adopted by the civil community of Rushden, Northamptonshire, as part of Warship Week in 1942.
Quorn joined the 21st Destroyer Flotilla at Harwich. The flotilla was tasked with convoy protection, anti-shipping and patrol duties. Quorn would stay with the flotilla for the whole of her commission. In April Quorn was superficially damaged by two delay-action bombs, that exploded from her port quarter.[3]
In August whilst on passage from Harwich to Chatham, Quorn set off a mine off her port bow. She was repaired at Chatham Dockyard. This took until September to complete.[3]
In April Quorn hit another mine that blew a 9x hole in the port side of the ship. Two of ship's company were killed and one injured. Her No 1 boiler room was flooded and major structural damage sustained. She was towed to Harwich and then to Sheerness where repairs took 4 months to complete.
On 13 October Quorn was one of the five destroyers that intercepted the German auxiliary cruiser in the English Channel. Komet was sunk and two M-class minesweepers were heavily damaged and set on fire. An hour later a second patrolling force of the same operation engaged a group of escort vessels, sinking an R boat, (minesweeper) and damaging a torpedo boat.
North Sea convoy protection duties with the 21st Destroyer Flotilla
In June Quorn was an escort for convoys of personnel during Operation Neptune, the naval support of Operation Overlord, the Normandy Landings. On 3 August, she was hit and sunk by a human torpedo piloted by Oberfernschreibmeister Herbert Berrer of the Kriegsmarine during a heavy attack on the British assault area by a force of E-boats, Linse explosive motorboats, human torpedoes and low flying aircraft.[4] Those that survived the initial attack spent up to eight hours in the water before being rescued, and many of these died. One hundred and thirty of her crew were lost.[5]
