For reference, here's that plan, which I didn't remember all of:
We're in the opposite direction, so we pass Curbiston on the way to meet the Duke and cross the river. This settlement has no value as a base, since it is not near where we plan to campaign.
March the prisoners away from the buildings, then say to the bilingual one: "You will be safe if you come with us; but if you run, you will be killed and someone near you will be killed. Tell your people that."
Gather whatever food stocks they have, set fire to the houses, and let's put distance between here and our encampment before nightfall. Let the watch be observant tonight, particularly if we remain near the coast.
As we ride, the halberdiers cover the prisoner band to landward, ready to cut in half anyone bolting into the undergrowth; the archers march to seaward, their eyes looking for ships; the heavy horse behind, and the rangers ranging in front. We will ride with the bilingual one in the next horse, perhaps riding double with Luther. We can ask questions on the march.
"Help us and your people will not be hurt."
"What is your name"
"Are there more men near the village?" (Observe body language.)
"What are your people doing in this land?"
"Who is your biggest chief?"
"How many Baabar have crossed the sea?"
"What false gods do you worship?"
Etc. I'm sure I've left some good ones out.
I would leave out "False" from the last question, advise using "most important" instead of "biggest" to prevent miscommunication and/or needless insult to their intelligence, and of course still object to "Baabar" on the grounds that they have no known resemblance to goats or sheep, but otherwise I have no objections.
