Answer:
B - Set to their village and ambush Spaniards that wonder away from their camp
Explanation:
By simulating a retreat, they lured the Spaniards out of their fortifications, and then, with the help of cunning, combined with incredible courage, they were able to gradually reduce the number of enemies. Unlike the eastern tribes, the Plains Indians rarely attacked settlements or forts of white people. Even if there were only a few dozen people inside and, according to Europeans, the settlement was poorly fortified, the Indians were well aware of the losses that could have been incurred as a result of a frontal attack, and avoided this. In the best case, they tried to lure some of the people out of the fortifications and trap them or get inside under a peaceful pretext, and only then attack.
