Why did the british need to evacuate dunkirk?

The evacuation boosted morale

Explanation:

If the BEF had been captured, it would have meant the loss of Britain's only trained troops and the collapse of the Allied cause. The successful evacuation was a great boost to civilian morale, and created the 'Dunkirk spirit' which helped Britain to fight on in the summer of 1940.

Why was the Dunkirk evacuation necessary? Nazi Germany invaded northern France and the Low Countries in May 1940 during the early years of World War II. With Belgium's surrender on May 28, an evacuation of French and British troops from the European mainland became imperative.
