The Unseen Blushers

An unearthly figure of gigantic hight, but lean and attenuated as a skeleton, terrorizes American soldiers and Mohawks. The figure was clothed in a tight black garment with steely gleams that covered it from head to foot, and a pair of short, upright horns projected from its close skull-cap, leaving exposed skin a face of deathly pallor, with great, burning black eyes, and a mustache that pointed upwards in true diabolical fashion.
Who-or what is this monstrous figure, and what does it portend for those it has made its enemies?
