So I decided to go hunting in canal. I found 2 large convoys and I was heavy outnumbered.... But then Luftwaffe arrived.
I found 2 Large Convoys in the canal...
Then the airplanes started to show up...
And started an attack run on Convoys...
Because no one cared about single u-boat I started attacking DD`s
Every minit more planes started their attack run...
10 planes attacking one poor merchant...
I sunk 3 of them... the rest was luftwaffe..
