What happened

Bypassing France's Maginot Line entirely, German tanks and infantry punched through the Ardennes Forest, a route Allied commanders had judged nearly impassable to armor, and reached the English Channel within days. Cut off and collapsing, more than 300,000 British and French troops were evacuated from the beaches around Dunkirk between late May and early June, ferried across the Channel by a makeshift fleet that included small civilian yachts and fishing boats alongside more than a thousand naval and merchant vessels. Paris fell on 14 June, and France signed an armistice on 22 June, ceding the northern coast and interior to German occupation while a new collaborationist government formed at Vichy in the unoccupied south.

Why it matters

Winston Churchill warned Britain not to mistake the Dunkirk evacuation for a victory: wars are not won by evacuations. But saving that army, rather than losing it entirely, was what let Britain keep fighting alone in western Europe for the next year, giving the war a second front to return to once the tide turned.

How we know

The evacuation's exact troop counts come from Royal Navy and merchant marine embarkation records kept at the time, and German advance timelines are corroborated by Wehrmacht and captured French command records on both sides of the collapse.
