Ok, Germany for what ever reason starts building U boats like mad and Karl Dönitz has a hundred boats on patrol, 100 more going to or returning from patrol, and the final 100 refitting in port. When the war started, could he get the British to quit from lack of food or fuel?
If I remember correctly the u boats darn near succeeded and there was less than a 60 boats at the time. Could more of them finish off the British?
