It's possible to finish off this quest AFTER the other people in a PUG has left.
Even if your group has skipped the patrols (and who doesn't), there are 12 cages available without killing any mobs.

The interesting thing is that all cages with prisoners are actually outside, not inside :-)
As of 10/6/12 this is 'bugged'. First time through releasing the prisoners did not give me credit. Next run through I was able to get credit. Not sure what to make of this.

Description
I sent a dozen of my best men ahead to infiltrate the mantid siege. None have returned. Since you are taking the fight directly to the mantid, you will be in a position to free any who had the misfortune to be captured. You will do this?
Getting there
Inside the dungeon: Siege of Niuzao Temple
Niuzao Temple extends across two fortified islands far beyond a towering wall called the Serpent's Spine. For years, tenacious pandaren defenders have protected the narrow bridges connecting the isles, staving off any would-be invaders.
Bosses in the Adventure Guide, in order: Vizier Jin'bak, Commander Vo'jak, General Pa'valak, Wing Leader Ner'onok.
