[@Blackmist16], I figured you must have skipped over some of the prior details. IC'ly, if Balothiss had decided to ignore orders and charge right in there and kill things, that would be fine because it's all IC stuff (it fits your character, after all, who is "very impatient and hotheaded at times but he enjoys ale and loves combat a lot"). However, considering that Balothiss had completely ignored the part where he would need to gain access to the village and instead just began existing in the heart of the village when nobody else had yet gained entry, that seemed very off to me.

Whatever, it's a bit late to undo it all. We can say that as the infiltration party moved into position Balothiss got excited, jumped the gun on the plan, charged through the village and started burning things. Then that puts us where the IC posts are, at a significant tactical disadvantage, of course, since now the guards and sorcerer priests have assembled in formation to counter the fiends invading their town. Balothiss might be able to beat aside a few lone guards, but the assembled military and magical might of the entire town? Not so much.

And no, an external distraction won't work. If the guards think they have already been breached, then, as has been said, they will fall back to the next line of defense, which is the town's center. And really, any other distraction won't do much, either. The defenses are already fully assembled. The best you can do is direct them to other places, which doesn't really help in beating them. With the original divide and conquer/subterfuge plan out the window, we'll just have to settle for a brawl.
