Came across a neutral Convoy (???) with only one escort (1 flower corvette) while sailing my IX U-boat to it's patrol grid. It contained 3 neutral ships (I want to sink, I want to sink!!) and a 50-50 mix of coastal / small merchants and C2 / C3's.
I trimed the Flower from the convoy

, then turned my sights on to the rest of the convoy. A single torp for the bigger ships (C2's and C3's) when deck guns to finnish them off if they don't go down. The coastal / small merchats, I found after a little trial and error, could be sunk using my twin 37mm ( I changed it's date of avaiblility)
I suddenly come under attack, but there are no warships or planes around, and the neutrals are doing anything aggressive. I then spot this....
The Greek's are armed and it's only late 1940!! I decided to sort him out by giving him two tin fish for dinner!!
I wiped out most of the convoy (two costal merchants left, along with the *%@$! neutrals). I have stumbled over a simlar convoy since then and have found a greek ship again armed and ready to turn me swiss cheese (or the greek version anyway)
Just thought I'd issue a warning to all who maybe in a simlar hunting environment.
