What was Operation Dynamo?

By the last week of May 1940, most of the British Expeditionary Force, along with French and Belgian soldiers, were trapped by the German army in a pocket around Dunkirk. Their only hope of escape was by sea, across the English Channel.

On the evening of 26 May, the British Government authorised an amphibious rescue mission, codenamed Operation Dynamo. In command was Vice Admiral Bertram Ramsay of the Royal Navy, who directed the operation from his headquarters at Dover Castle.

Over the next nine days, the men and women of Ramsay’s staff worked tirelessly from tunnels beneath the castle, coordinating a host of Royal Navy warships, merchant vessels of every sort and small civilian boats. Despite many ships being sunk and many lives lost, by the end of the operation on 4 June, Ramsay, his ships and staff had rescued 338,226 British and Allied troops and landed them in England. The rescue came to be regarded as a ‘miracle’, and remains the largest amphibious evacuation undertaken in wartime. It enabled Britain’s soldiers to regroup and fight again.
