The wrecks of three boats used within the Dunkirk evacuation within the Second World War have been uncovered for the primary time by an in depth survey of 30 shipwrecks off the coast of France.
More than 338,000 Allied troopers have been rescued by small boats from Dunkirk over 9 days between 26 May and 4 June 1940.
Historic England and its French counterpart, Drassm, carried out detailed surveys of 30 wrecks displaying their place, traits and situation in “remarkable detail”.
Historic England chief govt Duncan Wilson stated: “It’s very moving to see new details emerge from 30 shipwrecks linked to Operation Dynamo for the first time since the events at Dunkirk during the Second World War.
“We’re happy {that a} geophysicist from the UK, commissioned by Historic England, has been integral to the survey that has efficiently captured these particulars alongside Drassm’s unbelievable workforce of scientists.
“The results give us a striking insight into our shared heritage that still lies beneath the waters off Dunkirk.”
The most important instrument used for the survey was a multi-beam echo sounder mounted beneath the hull of the Drassm analysis ship Andre Malraux.

The instrument emits a fan of sound that’s recorded because it bounces off the seabed and the info is utilized by geophysicists to create a extremely detailed three-dimensional picture of seabed options equivalent to shipwrecks.
A complete of 27 Operation Dynamo wrecks have been positioned and studied, with the exact location of 12 not beforehand identified.
Four wrecks, both destroyed or coated by sand, couldn’t be positioned.
Previous identification ‘had confused the 2 wrecks’
A Historic England spokesperson stated: “A further 19 features have been studied, three of which appear to correspond to the location and characteristics of vessels lost during Operation Dynamo that were previously undiscovered.
“The identities of two wrecks – the French auxiliary minesweepers Denis Papin and Moussaillon sunk by air assaults on 1 June 1940 – have been corrected.
“The new data showed that previous identifications had confused the two wrecks.”
Many Dynamo wrecks ‘in comparatively good situation’
The spokesperson stated the survey knowledge was detailed sufficient to substantiate the identification of 19 wrecks by matching dimensions and options with historic images.
“On one wreck, the davits from which lifeboats once hung can be seen in the survey data. Their precise form – together with other details and dimensions – confirm that it is the Normannia, requisitioned as a troop carrier and sunk by an air attack on 30 May,” they stated.
“The survey has confirmed that many of the Dynamo wrecks are in relatively good condition.
“However, the brand new knowledge additionally exhibits current modifications.
“The destroyer HMS Keith was surveyed in 2016 and 2019 by the Port of Dunkirk (Grand Port Maritime de Dunkerque – GPMD). The 2023 survey shows that part of the destroyer’s hull has degraded in just a few years, collapsing away from its former position.”
The survey is the primary a part of an ongoing mission which is able to see native divers perform additional investigations subsequent yr, with the findings to be displayed in museums and on-line.
