Answer:
Step-by-step explanation:
Hitler's invasion of Poland on September 1, 1939, caused Britain to step up and officially order an evacuation. Dunkirk was a critical turning point in World War II. By 31 May, hundreds of civilian – from fishing smacks and cockle boats to lifeboats and sailing barges – had answered the Royal Navy's call for help and crossed the English Channel to Dunkirk.
German dictator Adolf Hitler's blitzkrieg strategy depended on maintaining concentrated forward momentum in its invasion of France and Belgium; Germany had overrun the region by May 1940.
Over 26,000 French soldiers were evacuated on that last day, but between 30,000 and 40,000 more were left behind and captured by the Germans. Around 16,000 French soldiers and 1,000 British soldiers died during the evacuation. 90% of Dunkirk was destroyed during the battle.
