1 - maybe Im a bit uneducated but plz explain the nature of the radio message "friendly task force in sector $$##". do u as a Uboat have to turn there and "protect them" as this friendly convoy goes its way? or do u just ignore the message and continue on your course?
2 - also when u're in the middle of the Atlantic, u sometimes get a message of a large enemy task force allllllll the way on the north side of england. obviously u can't get there in time (that would take upwards of a week) what do u do?
3 - and about the great allied air cover over britain - u cant swim at the surface - or it's near impossible. what to do in such situation (which only becomes worse when u cant man the flak guns due to bad weather.) the second u show ur %$#!@ above water, u get attacked! what do u do?
thank u!
