Because warriors depended upon the shield to protect them in battle, they went to great lengths not only to construct it as strongly as possible but also to have protective spiritual powers imparted to it. Here, Cheyenne gallop at full speed, shaking their war shields at the sun, then leaning down to brush them against the grass, invoking medicine believed to turn away enemy bullets and arrows.

A warrior might spend months making a shield, working and reworking until he was satisfied that it was done just right. Often he decorated it with symbols of his own personal medicine, given him by a spirit guide. He was likely to ring it with feathers and charms.
