Sinking Fishing Boats - Bad Form?

[siber]

Hi guys & gals!

Here's a connundrum for you all. Fishing boats: Should you sink them, or take pity and decide that 90t isn't worth an expensive torpedo paid for by tax-payers.

On the one hand, it's 1940, the fishermen aren't armed, Germany's romping across Europe, and it's not as if they're carrying 'war supplies' (fish?). Sinking the fishermen would surely be morally wrong. It goes against all the German ideals of chivalry. I should save the torpedo for a more worthwhile target.

On the other, the sooner Britain starves, the sooner she capitulates. Potentially, the fishermen are six weeks training away from being soldiers, sailors or airmen, and I may not even find another proper target before I have to head back to base anyway. Use the torp, sink the fishing boat, take 90t and help starve Britain into submission while depriving her of manpower.

Should I sink the fishing boat? I'm at 90 deg. AOB, 650m out, submerged. It's pootling along at 8kts and hasn't got a clue... What do you do?
