The Dunkirk evacuation, code-named Operation Dynamo, also known as the Miracle of Dunkirk, was the evacuation of Allied soldiers during World War II 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 long Battle of France. In a speech to the House of Commons, British Prime Minister Winston Churchill called this "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".
On the first day only 7,669 Allied soldiers were evacuated, but by the end of the eighth day, 338,226 of them had been rescued by a hastily assembled fleet of over 800 boats. Many troops were able to embark from the harbour's protective mole onto 39 British Royal Navy destroyers, four Royal Canadian Navy destroyers, and a variety of civilian merchant ships, while others had to wade out from the beaches, waiting for hours in shoulder-deep water. Some were ferried to the larger ships by what came to be known as the little ships of Dunkirk, a flotilla of hundreds of merchant marine boats, fishing boats, pleasure craft, yachts, and lifeboats called into service from Britain. The BEF lost 68,000 soldiers during the French campaign and had to abandon nearly all of its tanks, vehicles, and equipment. In his speech to the House of Commons on 4 June, Churchill reminded the country that "we must be very careful not to assign to this deliverance the attributes of a victory. Wars are not won by evacuations."
The Phoney War (Drôle de guerre, Sitzkrieg) was an eight-month period at the start of World War II, during which there was only one limited military land operation on the Western Front, when French troops invaded Germany's Saar district.
The Phoney period began with the declaration of war by the United Kingdom and France against Nazi Germany on 3 September 1939, and ended with the German attack on France and the Low Countries on 10 May 1940. While there was no large-scale military action by Britain and France, they did begin economic warfare, and shut down German surface raiders. They created elaborate plans for numerous large-scale operations designed to swiftly and decisively cripple the German war effort. These included opening a French-British front in the Balkans; invading Norway to seize control of Germany's main source of iron ore; and a strike against the Soviet Union, to cut off its supply of oil to Germany. Only the Norway plan came to fruition, and it was too little too late in April 1940.
The quiet of the Phoney War was punctuated by a few Allied actions. In the Saar Offensive in September, the French attacked Germany with the intention of assisting Poland, but it fizzled out within days and they withdrew. In November, the Soviets attacked Finland in the Winter War, resulting in much debate in France and Britain about an offensive to help Finland, but the forces finally assembled for this campaign were delayed until it ended in March. The Allied discussions about a Scandinavian campaign caused concern in Germany and resulted in the German invasion of Denmark and Norway in April, and the Allied troops previously assembled for Finland were redirected to Norway instead. Fighting there continued until June when the Allies evacuated, ceding Norway to Germany in response to the German invasion of France.
On the Axis side, the Germans launched attacks at sea in the autumn and winter against British aircraft carriers and destroyers, sinking several including the carrier HMS Courageous with the loss of 519 lives. Action in the air began on 16 October 1939 when the Luftwaffe launched air raids on British warships. There were various minor bombing raids and reconnaissance flights on both sides.
