Could I ask what that has to do with Hitler having an upper hand when it came to U-boats, or are you referring to the fact that he lost the upper hand because those two events occured?Zenode said:but for me my favourite one is the German U-boats they basically gave Hitler the upper hand in WW2 (but the Japs hit Pearl Harbour and he attacked Russia)
OT: My favourite is the Welrod.

It's the centre one of course.
