At around 7 p.m. on 26 May 1940, Prime Minister Winston Churchill gave the order for Operation Dynamo, the evacuation of British troops from the harbour and beaches of Dunkirk. The German forces that had attacked through the Netherlands, Belgium and the Ardennes into France on 10 May had rapidly driven to the English Channel, reaching the coast at Noyelles-sur-Mer on 20 May and trapping the BEF, French forces and the remnants of the Belgian army. BEF commander Lord Gort immediately began to plan for his forces to withdraw towards Dunkirk, the nearest location with good port facilities. Between 27 May and 4 June, ships from the Royal Navy, the Merchant Navy, France, Belgium and the Netherlands as well as the famous Little Ships evacuated almost 340,000 Allied troops from Dunkirk and brought them back to Britain. However, the Dunkirk evacuation was not the end. In Operation Cycle just over 11,000 Allied troops were evacuated from the port of Le Havre between 10 and 13 June. Later still, in Operation Ariel, another 190,000 troops and between 30,000 and 40,000 civilians would be evacuated between 15 and 25 June from ports along France's western coast including Brest, Saint-Nazaire and Bordeaux. This evacuation would see the greatest loss of life in a British ship when the Luftwaffe bombed and sank the troop ship Lancastria in the estuary of the Loire. In this book, author Henry Buckton examines the Dunkirk evacuation, the rapid German advance that led up to it and the evacuations that came after.
