Flabbergasted Thistletop (Rise of the Runelords) Approach

My player and I were doing a little off-table play so she would be set and ready to rip into Thistletop in a few days IRL, and she made a move that really has me pondering and contemplating the situation.

It's a solo power fantasy gestalt campaign, so her character is optimized to the gills far beyond what would be normally allowed in a group game. But she's still just a single mighty adventurer staring down the layer of several dozen goblins.

The lass whipped out her brass balls and a scroll of Clarion Call and shouted out to the entire tribe gathered in Thistletop's Outer Region (very well may be heard by the guards on the watchtower as well, I haven't rolled their perceptions yet) in Goblin

"Goblins of Thistletop, here me and listen well! I am Misha, scion of the heavens and harbinger of your demise. I was there when you raided Sandpoint, and I was there when your longshank raid leader fell thereafter. A full score of your kind have fell by my hand this week, and many more to come this day. I stand before you now to destroy not your lives but your will to war. All who wish to live, flee while you can and never attack a town again. The rest shall be made an offering to Valhalla by my hands. Choose wisely."

So, while I ponder how the encampment will respond at the start of our session, what would you do?

She has an impressive reputation, she's clearly dangerous... But she's all alone and there's tremendous courage in numbers. Do they underestimate her and launch an all out assault? Do they cackle at the stupid meaty longshank and ready their defenses inside the brambles? Or do they make a morale check and those who fail run for their lives?
