Compromised by goatherders.
Wasn't there another film "based on a true story" about a Special Forces unit behind enemy lines, that was compromised by an old man, a couple of boys and some goats?
Ten seconds googling "Special Forces unit behind enemy lines, that was compromised by an old man, a couple of boys and some goats" came up with Bravo Two Zero and Lone Survivor.
So I've answered my own question I suppose?
