Why did Hitler decide not to destroy the British Army at Dunkirk?

Answer 1

This is one of the most widely debated situations in World War II. Historians knew that Hitler was nervous about risking his tank forces, and he wanted to wait until more infantry arrived. There is also some evidence that the Luftwaffe alone would obliterate the trapped soldiers. Hitler might also have wanted to halt the invasion so that Britain would accept surrender more easily if Hitler didn't humiliate Britain by destroying her army.
