Since it seems the party is being hunted by two different groups (the shadow/sidhe and the inquisition) how about just running the encounters in opposite order?
The Inquisition locates the PC's, captures them and strips them of their weapons (let them keep armor though) - They are suspicious, but can't quite believe the PC's are responsible and want the PC's for questioning.
Have them be as fair as possible, so that the PC's will agree to surrender without a fight.
Then have the shadowmen attack (remember to use all their abilities), let the PC's see how dangerous they are, but unable to do anything (due to being unarmed and possible bound). when the fight starts to go against the inquisition, let the inquisition accept the help the PC's have probably been offering since the fight started.
The PC's may win this or they may not - either way you get some benefits from this solution:
1. The forces of good (inquisition) are as active as the forces of evil (shadowmen)
2. The PC's do not feel like they are being rescued!
3. The PC's feel like heroes - whether others agree is a different story, the inquisition might still hold a grudge for getting them in the mess in the first place.
