When the depth is not enough i usualy go to 10 meters from keel and run at 1 knot silent,watching the map for the contacts and when i hear noise of "flank ahead" over my head i dont think twice,go to flank and 90 degrees turn then again 1knot silent. Few minutes ago i run into a task force im sure 4 destroyers and 2 battleships and 2 other witch i didnt recongnize but in any case saw them little more than a kilometer from me directly on 90 degrees on me.I tried to dive imediatly but DD open fire one closed from behind and a shot without a solution sunk one and i dive to 90 meters (bottom was 100) and on zig zag i think they run out of deph charges because it seems they moved on top of me but didnt drop.Well i have suffered a dmg that destryed mine conning tower and the guns but i survived
though almost a hour real time without tc
