Four years before the Normandy landings, the French coast was the scene of another major episode in the Second World War. This was Operation Dynamo, much less well known than D-Day. And yet you only have to look at the statistics to see how important this part of the story of the Campaign of France was : between 27 May and 4 June, almost 340 000 French and British troops were evacuated from the Dunkirk pocket by a miscellaneous fleet of 850 boats, among which hundreds of fishing vessels, pleasure boats, lifeboats or Merchant Navy vessels. Thanks to the sailors’ courage but also the RAF pilots’ skill, this operation without precedent was a success which enabled the British to continue to fight the Germans, even though they had to leave behind most of their equipment and weapons. Replaced in its context, Operation Dynamo is here narrated in detail with numerous period photos, maps, aircraft profiles and uniform plates.This military operation and human adventure without precedent breathes again, 77 years later thanks to the film director Christopher Nolan, the author of the Dark Knight trilogy and Interstellar which, with Dunkirk, has become an international blockbuster, to which a chapter of this book is devoted.
