Hello guys i have a quick question.
After trying to learn game basics at '39 campaign more than a month i have started '40 campaign with increasing the game reality a bit more.

(SH3+GWX)
Now i am at my second patrol(sunk three ships already

) .Anyways here is the question.While engaging enemy merchants i am launching one torpedo and if it is not sinking with that i am rising up to 5 meters or so then maning the deck gun and boomm its sinking.the question is , is that a bad idea to let them know i am around?or are they gonna tell the big guys (like destroyers ,other warships etc.) my current plot ? i am using my current tactic to save torpedos.
thanks.
Can
