Frequently told stories concern the miraculous protection that the sacred underwear has afforded. In war, shrapnel and slugs have penetrated the outer clothing but failed to penetrate the garments. When a Saint was caught in a treacherous snowslide all his clothing save the garments was torn to shreds. In southern Utah, when Indians made a raid on some Mormons and killed them, the corpses that wore sacred garments were unmolested; the others were scalped.
