I took your advice Ford Perfect and tried careers in 3 later dates (during the war). In all cases l had no enemy traffic nor any axis nor any neutral shipping or aircraft traffic. In Career mode, I have the sea all to my self. I transited the English channel in broad daylight with no contact. There simply is no other traffic of any kind in the Career mode, other than my lonely sub. I am desperate for some help here
. Just imagine, starting a war and nobody comes!!! Help Help ?
