(OW) Have all people evacuated to the south of the village, and retreat from the village
From Create Your Own Story
You and your soldiers have all villagers evacuated to the south of the village, behind a ridge. The Americans cannot shoot at you from the hill, but they can come down from the hill and destroy your village. If they come down, you could easily attack them by hiding behind the teepees.
Wait for the Americans to come down from the hill, and charge them with the horses.
