November 1940, I take on a convoy sucessfuly for the first time. Sneak in without being detected, Fire four torpedos at three different ships (two large merchants and a pryo ammo carrier) Three hit and all thee ships go to the bottom! Fire the aft tube as a snap shot on a small merchant, it hits!! Brings it to a halt.
The escorts sniff around but never detect me. Let the convoy go (only contains tramp steamers, coastal and small merchantmen now!

) When there over the horizon I surface, man the deck gun and fire two rounds into the small merchant which sinks.
I then do a harbour raid which bags me another 35,000 tons. Uncle Karl had my photo on his desk after that!
