Admiral Sir Bertram Home Ramsay, KCB, KBE, MVO was a Royal Navy officer. He commanded the destroyer HMS Broke during the First World War. In the Second World War, he was responsible for the Dunkirk evacuation in 1940 and planning and commanding the naval forces in the invasion of France in 1944.

The Dunkirk evacuation, codenamed Operation Dynamo and also known as the Miracle of Dunkirk, or just Dunkirk, was the evacuation of more than 338,000 Allied soldiers during the Second World War from the beaches and harbour of Dunkirk, in the north of France, between 26 May and 4 June 1940. The operation commenced after large numbers of Belgian, British, and French troops were cut off and surrounded by German troops during the six-week Battle of France.
