Yes, like the famous battle of the Dunkirk. Gosh, 'twas glorious.
Middle of the night, as the Germans were about to approach the next day after they woke up, the British got on little rafts and fled the Dunkirk. And when the Germans got to the Dunkirk the next day, the Dunkirk was empty. It was a turning point in the war because of Dunkirk was empty.
The rest of the war they hunkered down in the Tunnel which for some reason is miles underground while London was getting obliterated.
Perhaps if they were told that the Germans were Asian villagers that had to be massacred in order to acquire exotic spices that to date the British still have not used in what has got to be the blandest food on the planet, the British might have fought back. But alas, they had to wait for the Bloo'y Yanks to rescue them.
Then after the war was over, there were so many guns left, that the villagers that the British used to shoot like rubber duckies in a bucket for target practice were now able to shoot back, and so the sun set on that empire. Ok, tbf, part of that was a deal that Roosevelt made with Churchill that in order to save his ass the Brits had to give up the colonies, but it sure took them a few decades to do so with a few bullets to the head, so there was that.
