HMS Fleur de Lys was a Flower-class corvette that served in the Royal Navy and was built by Smith's Dock Company in 1940. She was named after Fleur de Lys. Commissioned in 1940, rammed and sunk by U-206 on 14 October 1941. Her name was originally La Dieppoise and built for the French Navy but was later changed.

Design and description

In early 1939, with the risk of war with Nazi Germany increasing, it was clear to the Royal Navy that it needed more escort ships to counter the threat from Kriegsmarine U-boats. One particular concern was the need to protect shipping off the east coast of Britain. What was needed was something larger and faster than trawlers, but still cheap enough to be built in large numbers, preferably at small merchant shipyards, as larger yards were already busy. To meet this requirement, the Smiths Dock Company of Middlesbrough, a specialist in the design and build of fishing vessels, offered a development of its 700-ton, 16 knots (18 mph; 30 km/h) whale catcher Southern Pride . ^{[1] [2]} They were intended as small convoy escort ships that could be produced quickly and cheaply in large numbers. Despite naval planners' intentions that they be deployed for coastal convoys, their long range meant that they became the mainstay of Mid-Ocean Escort Force convoy protection during the first half of the war. The original Flowers had the standard RN layout, consisting of a raised forecastle, a well deck, then the bridge or wheelhouse, and a continuous deck running aft. The crew quarters were in the foc'sle while the galley was at the rear, making for poor messing arrangements. ^[3]

The modified Flowers saw the forecastle extended aft past the bridge to the aft end of the funnel, a variation known as the "long forecastle" design. Apart from providing a very useful space where the whole crew could gather out of the weather, the added weight improved the ships' stability and speed and was retroactively applied to a number of the original Flower-class vessels during the mid and latter years of the war.

Construction and career

Fleur de Lys was laid down by Smith's Dock Company at their shipyard at South Bank, on 30 January 1940 and launched on 21 June 1940. She was commissioned on 26 August 1940.

HMS Fleur de Lys was on an convoy escort mission OG-75 off the Strait of Gibraltar. U-206 fired 3 torpedoes at the port side of Fleur de Lys which cause a chain reaction to go off. Her magazine exploded and the ship broke into two. 70 of her crew went down with 3 rescued by a Spanish motorboat Castillo Villafranca. ^[4]
