Heinz Guderian: "How many people do you think even know where Kursk is? It is a matter of profound indifference to the world whether we hold Kursk or not. I repeat my question. Why do we want to attack in the East at all this year?"
Adolf Hitler: "You’re quite right. Whenever I think of this attack my stomach turns over."
Heinz Guderian: "In that case your reaction to the problem is the correct one. Leave it alone!"
