Sonar Survey Reveals the Lost WWII Ships of Dunkirk
A crew of French and English researchers have surveyed the websites of 30 shipwrecks from Operation Dynamo, the sealift that saved Allied troops from advancing German forces at Dunkirk in 1940.
Operation Dynamo, often known as “the Miracle of Dunkirk,” concerned the evacuation of tons of of hundreds of Allied troopers who had been surrounded in the course of the fast German invasion of France. The port infrastructure at Dunkirk was shortly destroyed by German heavy bombers, so embarkation shifted to the seaside and to an ad-hoc pier on the harbor’s breakwater. To switch the trapped and susceptible troops, a swarm of 1,000 vessels – warships, passenger ships, fishing boats, workboats and yachts – made the crossing from England from May 26 to June 4, 1940.
The effort introduced 340,000 British and French troops throughout the Channel to England – however not and not using a price. These ships had been uncovered to naval mines and the dive bombers of the German Luftwaffe, and greater than 240 had been sunk, together with about 170 small craft. The vessels on this ad-hoc fleet had been celebrated by the British authorities and remembered as “The Little Ships of Dunkirk.”

Historic England and French analysis institute Drassm have labored collectively to plan a survey of the misplaced vessels of Dunkirk, and the mission started in late September. Archaeologists Cécile Sauvage and Claire Destanque of Drassm performed the survey aboard the analysis vessel André Malraux, assisted by two geophysicists. Using a multibeam sonar, the crew made an in depth three-dimensional profile of the seabed off Dunkirk. They discovered 27 wrecks from Operation Dynamo, together with a dozen that weren’t beforehand situated with precision.
Three extra previously-undocumented wreck websites had been additionally found, bringing the whole to 30. The survey additionally revealed that among the identified wrecks – just like the misplaced British destroyer HMS Keith – are steadily deteriorating.
The multibeam survey is the beginning of an extended marketing campaign to analyze the wreck websites and doc them of their present state. Next yr, in partnership with native divers, Drassm’s researchers will return to hold out an in depth dive survey.
