The AI by the "enemy"

[bigboywooly]

I suspect the Irish attacked you as you had sunk one of their ships in the previous 24 hr

Unfortunately the AI behaviour is hardcoded
Yes convoys should disperse but they dont and not a thing we can do to make them
Would certainly be a better way to act but - meh - what you gonna do
