21st December 2023 marks the 80th anniversary of the loss of Chasseur 5/Carentan named after the port of Carentan on the Cotentin peninsula in Normandy. She was one of a number of French chasseurs sous-marins or submarine hunters ordered in 1937 and which entered service in the French Navy in 1940. [Images Défense gallery of official photographs of Chasseur 5 taken in early 1940 including remarkable views of a seaplane under tow.]

Along with Chasseurs 6 and 7, 9-11, 41 and 42, Chasseur 5 took part in Operation Dynamo, the evacuation of Dunkirk, over May-June 1940. [1] Sixteen Chasseur-class vessels were then stationed in Britain and entered the service of the Royal Navy as fast patrol and escort vessels. Although Chasseurs 6 and 7 were sunk off St. Alban’s Head under the White Ensign in October 1940, as early as July 1940 the Chasseurs began to be turned over to the Free French Navy (FNFL) and to be renamed in FNFL service after French coastal towns. For example, Chasseur 8 re-entered service under the FNFL in April 1941 as Rennes, to be attacked and sunk off the Lizard in one of the ‘tip and run’ raids of July 1942. [2]

Chasseur 5 was similarly renamed Carentan, but in most British records seems to have kept the designation Chasseur 5 with no real consistency over the nomenclature, including HMS Chasseur 5, while French records similarly note the vessel as Chasseur 5 “Carentan”. [3] There is likewise some confusion over when the vessels actually entered Free French service, for example the July 1940 date, or, as some French sources state, in 1943 – the latter following a refit at Marvin’s (Coles) Yard, Cowes, Isle of Wight, where the Free French Chasseurs were stationed from 1940-1945, commanded by the 1st Destroyer Flotilla. The earlier date of 1940 seems more likely given the fact that they were assigned a base at Cowes from 1940, and named as the Chasseur Flotilla of French ships there in January 1942, including Carentan (Ch. 5).

As the war memorial to the Free French Submarine Chasers on the Isle of Wight states, in a bilingual inscription: ‘They were in the fighting line in the Channel, notably in the Cowes blitz, Bruneval and Dieppe raids, Liberation of France.’ [The Cowes blitz took place in May 1942.]

On 21 December 1943 Chasseur 5/Carentan, under Lieutenant de vaisseau Michel Pierre Sauvage, alias Sampson, was assigned to escort HMS Rorqual, a minelaying submarine of the Grampus class which were all named after sea creatures, from Brixham to Portsmouth. As they passed St. Alban’s Head that morning, the sea conditions deteriorated to force 7 (some sources state a SW force 9 gale) and when a huge wave struck her, she capsized.

Contemporary RNLI records state that a ‘strong and increasing south-west wind was blowing, with a heavy sea, and visibility was very poor at times’, while Met Office records show that conditions were consistently southerly force 5 between 0100 and 1300 that day off Portland Bill. These official observations were, however, point-in-time snapshots, and it appears likely, therefore, that the wind got up at mid-morning in the interval between the 0700 and the 1300 reports. [5]

At 10.27 the Swanage coastguard summoned the Swanage lifeboat Thomas Markby to go to the assistance of ‘an escort vessel which had capsized three miles south of Durlston Head.’ Less than 20 minutes later after the launch of the Thomas Markby, she reached what proved to be ‘Chasseur 5, a chaser of the French naval forces’. Rorqual was standing by as three men from Chasseur 5 clung to the capsized keel, and ‘it was only by skilful seamanship that they were rescued’ by the lifeboat. [5]

Rorqual then rescued four more of Chasseur 5‘s crew, but without tools the lifeboat Thomas Markby was unable to assist the remainder of the crew trapped in the vessel, who could be seen through a porthole. Thomas Markby arranged with Rorqual to ‘pump oil on the sea’, the classic ‘pouring oil on troubled waters’ to calm the sea in extremis, and returned to Swanage to land the rescued men and pick up saws and axes to break into the stricken vessel. However, on the return voyage the Thomas Markby was met with the news that Chasseur 5 had sunk with the remaining crew, three of whom were British.

The site of Chasseur 5/Carentan has been identified since the 1960s 1.75 miles SE of Anvil Point, Dorset. It is now a well broken wreck but, with the loss of life involved, it clearly remains a maritime grave with ample evidence of its military purpose, including shells and depth charges still in situ.

Diary of the Second World War – June 1943

HMS Sargasso

From the point of view of shipping losses, June 1943 – in English waters at any rate – was a quiet month with only two recorded losses. One of those was HMS Sargasso, a yacht requisitioned in 1939 as a danlayer.

At this distance in time, danlayer operations are somewhat obscure so it is worth explaining exactly what a danlayer is, or was. They were primarily small coastal fishing or other craft which were requisitioned the Second World War to operate in tandem with minesweepers, themselves often trawlers.

Minesweeper and danlayer personnel received a common training – there was an officers’ course, which took in Royal Naval Volunteer Reserve officers from Australia, Canada, India and New Zealand, as well as US personnel, Belgians, Dutch and Norwegians. For ratings there was a three-week ‘Hostilities Only’ course ‘so that they may take their places as efficient members of any minesweeping ship, whether she be trawler, drifter, dan-layer or fleet sweeper.’ [1]

The minesweeper-trawler went back to the First World War, but the danlayer is a specifically Second World War concept, and, as a consequence, lost danlayers are also a form of loss unique to the Second World War.

Like minesweepers, they were particularly prone to being lost to unswept mines on the periphery of the swept area, as in fact happened to HMS Sargasso. Girl Helen and HMS Elk, also sank in this way in 1940, but HMS Comfort was lost in a collision in the melee off Dover while coming to the assistance of torpedoed vessels in Operation Dynamo, 1940, and HMS Gulzar was bombed from the air, also in 1940. [2]

The Germans also requisitioned ships as danlayers in a very similar fashion during the Second World War and the Dutch coaster Seaham, ex Oceaan, was commandeered on the fall of the Netherlands for this purpose, serving as Wangerooge. Post-war she was returned to her owners and reverted to the name Seaham, trading once more with Britain. She was lost in 1952 off Lowestoft on the Hull-Rotterdam route. [3]

So what exactly was a danlayer? For every channel that was swept clear of mines by the sweepers, it had to be marked. They were marked by dan buoys, which, according to dictionary definitions, is specifically British English usage. A dan buoy is a ‘small buoy used as a marker at sea’, particularly ‘used as a marker in deep-sea fishing’ or ‘showing the limits of area cleared by minesweepers’, and with a ‘coded flag’ at the top. [4] So the danlayers followed the sweepers as the gulls follow a trawler at sea.

The photograph below shows a danlayer at work in clearance operations in the immediate post-war period.

Of the known danlayer losses of the Second World War within England’s Territorial Sea two have been discovered and charted, HMS Sargasso and HMS Elk (the remains of the latter not confirmed). HMS Sargasso has been identified off the coast of Dorset with weights for dan markers discovered aboard and forming part of the identification process. [5]

Already a rare group of vessels, confined to the war years, few have been identified, and only on this one example is the function of the vessel legible in the remains: the Sargasso has a significance beyond her size.
