If they truly had only 2 escorts, and one was the Rodney, then I think I may have taken out the tribal, allowing me to easily take out the rodney, as it is a worthy prize on it's own, and then get what merchant shipping I could have.

But I really doubt there was only the one DD, They seemed to keep a DD or Frigate at least on each flank of the convoy. offering a ASW screen, while the BB in the middle was used for ASUW mainly.

If your were hell bent on scoring a big kill here and hopefully getting away, I like to drift in slowly (50 rpm), getting up close and personal with the convoy. Then I fire off killing or at least disabling salvo at the primary target in the convoy (in this case the Rodney). I reload and fire off a nice wide spread 4 eel salvo at another high value target when the first eels are close enough to guarantee a hit before the seconds are detected. This will usually stop/kill the primary target, while having a good chance of slowing the second, and picking up a couple tertiary targets too. Then I dive and go really really silent while the convoy runs over me, letting the merchants run interference on the DD's hunting me.

But if you were shallow here, I'd fire off a good salvo at the Rodney and quickly went silent and tried to slip away. Hopefully you'll disable something and be able to pick it up later.
