Could you believe i have November 1939 and i never had a chance to fire torpedo yet? I never saw any enemy merchant ship. Just ****ing fishing boats, destroyers, or Norway merchants at east coast.
I saw British merchant just from 5m distance in heavy fog because i was unable to see the flag on longer distance.
But it was in 15m/s wind anyway, waves didn't allow me to fire even by deckgun..
75% of time i have constant 15m/s wind, heavy fog, heavy preciptation.
For tens of hours i am just robot to changing air in sub, decoding messages and listening to hydrophone, gaah!
