The successful evacuation of Allied troops boosted the British morale alright, but it ended a wholly unsuccessful campaign in which the Germans separated the remaining French and Belgian armies, cutting them off from helping the troops who had retreated to Dunkirk. It left the French and Belgians alone to fight the Germans, and they were soon forced to surrender. It should also be pointed out that the German decision to halt their offensive for three days allowed the British time to evacuate. This decision was criticized at the time and has been debated for decades afterward. Had the Germans pushed forward, they would have probably isolated the entire Allied force on the beaches and forced their surrender. The German decision to halt was to make certain that the French and Belgians would not be able to break through and meet up with the isolated Allied Forces. In the end, it gave the Allies an additional 300,000+ men to fight again, but it also gave up the European mainland to full control of the Germans.
