I need to revisit their embassy for a little "gunboat diplomacy", but using a bow instead of a gunboat. You can find the embassy NW of Solitude. Head west while keeping an eye open for a road to the north. That should take you there.
I seem to run into more of their patrols (not all of them have prisoners) when I'm near a Stormcloak camp. Maybe coincidence. Also, after sacking Solitude and hearing Ulfric's speach, I went down to check on Proudspire. Would you believe a Thalmor patrol rounded the corner as I approached the house? Still as high-handed as ever. I told the prisoner to leave and attacked the justicars. Well, things were lively, as Aela used the Sanguine Rose and Galmor Stone-fist and Ulfric arrived on their way to the Blue Palace.
There's something about friendly fire that can really mess things up. The dremora or Aela injured Galmor and boy was he pissed. Ulfric got knocked down, the dremora returned to oblivion, and Aela finally knocked Galmor down as well. I sheathed my weapons and retired with alacrity into Proudspire. Okay, I thought, maybe we'll wait till things chill a bit. No such luck, as Galmor let himself in, muttering that he thought he heard something. He walked right past Aela, then turned and saw her, and the fight was on again. I ended up having to reload a saved game, but the Thalmor patrol appeared on cue again. This time I dealt with them without any, er, complications.
