Battleship tonnage or the merchant shipping?

[JohnnyBlaze]

It's november 1940. U-83 IXB class out of Lorient, France.


I spotted a large enemy convoy at AM29 heading east. As I made my first attempt to get in to a firing position at the middle of the night I got spotted by one of the ships in the outer column. Distance to the ship was 2000meters. I immediately break off from the convoy as a flower class corvette came after me. I could out run him on the surface, but I thought it would be a lot harder to approach the convoy on my second attempt so I decided to engage in a surface duel with the corvette. At about 4500m distance I order my gunners to aim for the turrets on the corvette. After about 15-20 shots later I had crippled the corvette and his guns when I realized his buddy (the rear escort) is blazin his guns at me about 3000m away. I didn’t want to take the risk to do a surface battle again cuz my boat took some damage from the first duel. So I flank away from the escort which happened to be a flower class also.

The escort went back to his post after chasing me about 20 minutes.
Now I'm trying to locate the convoy again to get some tonnage out of it.

There was a Revenge class battleship in the middle of the convoy and a couple of fat tankers on the next column.

What do you guys think should I go for the Revenge class or just settle for the tankers that are a bit closer to the side of the convoy? The two Tankers are about 16000t for each and the Revenge class is 31000t.

I only have 4 torpedoes left so I have to choose wisely. And that's when you guys come in

Any thoughts?
