The Dunkirk evacuation, code-named Operation Dynamo, also known as the Miracle of Dunkirk, was the evacuation of Allied soldiers from the beaches and harbour of Dunkirk, France, between 26 May and 4 June 1940, during World War II. The operation was decided upon when large numbers of Belgian, Canadian, British, and French troops were cut off and surrounded by the German army during the Battle of France. In a speech to the House of Commons, British Prime Minister Winston Churchill called the events in France "a colossal military disaster", saying "the whole root and core and brain of the British Army" had been stranded at Dunkirk and seemed about to perish or be captured. In his We shall fight on the beaches speech on 4 June, he hailed their rescue as a "miracle of deliverance".

After Nazi Germany invaded Poland in September 1939, France and the British Commonwealth and Empire declared war on Germany. The British Expeditionary Force (BEF) was sent to aid in the defence of France. After the Phoney War, Germany invaded Belgium and the Netherlands on 10 May 1940, and three of their Panzer corps attacked France through the Ardennes and rapidly drove to the English Channel. By 21 May, the German forces had trapped the BEF, the remains of the Belgian forces, and three French armies in an area along the northern coast of France. Commander of the BEF, General The 6th Viscount Gort, immediately saw that evacuation across the Channel was the best course of action and began planning a withdrawal to Dunkirk, the closest location with good port facilities. On 22 May 1940, a halt order was issued by the German High Command, with Adolf Hitler's approval. This gave the trapped Allied forces time to construct defensive works and pull back large numbers of troops toward Dunkirk, to fight the Battle of Dunkirk. From 28–31 May 1940, in the Siege of Lille, the remaining 40,000 men of the once-formidable French First Army fought a delaying action against seven German divisions, including three armoured divisions.
