Congrats, mate...
Just made an estimation I still have roughly 4500 kms to go back to W'haven (am standing around B47)
Think I will speed up the trip a bit as I have only my 2 external torps left and waiting for better weather to bring them in ( just crossed a huge convoy tonight, just had to let it go...
) Have already 35000 t and can still hope to gun down a few on the way back, weather permitting.
