Ive been palying for a while now but I have just run into my first convoy.
I came in ahead of the convoy, destroyed the lead and only escort, a corvette with a lucky torpedo shot. Then i slipped into the convoys lines with the plan to ID the ships because the stormy weather stopped me from commiting an underwater attack and I can't go to town with the deck gun. I have IDed a coastal frieghter, a C2 cargo and a T2 tanker.
But I didn't aline myself properly and now I am a few metres away from the tanker, just underwater.
This being my first convoy attack I do not know the procedure. My main question is how am i doing so far?

P.S Im using vannila i can't find a GWX install I can use
