Small heads up.
Was just sunk by a hunter group consisting of
6 destroyers and
one light cruiser accompanying 1 (one) Cimarron tanker, in october 1939.
At 160 meters, running silent with 50 revolutions/minute and the crew put to rest.
The first two depth charges hit at my exact depth, at the exact point, one meter left and right of the conning tower

(Had i survived i had told Donuts he can put his U-boats were the sun don't shine; the british defence is invincible

)
Have to find out where to lower the AI settings .. maybe there is a setting for zero, or maybe
-1.
