On a sienote... baz was pirating my merchants and trespassing through my PD without permission... so I declared war on him. I didn't realize that he's actually a pretty big empire. Here's hoping I can resolve the issue quickly.
Problem with pirate fleets is they attack everyone you pass, not just your target
You might want to find out if you were his target and remind him to leave his fleets in something other then pirate until he arrives.
