“When I said that the French Army, fighting on, wherever it might be, could hold or wear out a hundred German divisions, General Weygand replied, ‘Even if that were so, they would still have another hundred to invaded and conquer you. What would you do then?’ On this I said that I was not a military expert, but that my technical advisers were of opinion that the best method of dealing with German invasion of the island of Britain was to drown as many as possible on the way over and knock the others on the head as they crawled ashore.” – Winston Churchill, Their Finest Hour
