[Hambone307]

I usually wait until nightfall before attacking escorted convoys. Once it is sufficiently dark out, I get in close to the convoy, identify the escorts and then attack the trailing DD from close range with a torp on fast settings. After the trailing DD is hit, usually disabled, I pull back and circle to the front of the convoy. This leaves the remaining escorts at the back of the convoy, allowing me plenty of time to get shots on several merchants. Once the DDs start to move back towards me, I pull back and circle to the rear to get shots on the other side.

My personal preference is to apply this tactic to large escorted convoy. Once the trailing DD is hit, the preverbial pot is stirred and I have free reign on the merchants while the escorts run back and forth. I have done this for several in game months and have only been shaken up a couple times.

The only time I seek out destroyers is when I am low on tonnage and near a narrow strait with plently of water beneath me.
