henchman (n.) Look up henchman at Dictionary.com
mid-14c., hengestman, later henshman (mid-15c.) "high-ranking servant (usually of gentle birth), attendant upon a king, nobleman, etc.," originally "groom," probably from man (n.) + Old English hengest "horse, stallion, gelding," from Proto-Germanic *hangistas (cognates: Old Frisian hengst, Dutch hengest, German Hengst "stallion"), perhaps literally "best at springing," from PIE *kenku- (cognates: Greek kekiein "to gush forth;" Lithuanian sokti "to jump, dance;" Breton kazek "a mare," literally "that which belongs to a stallion").

Perhaps modeled on Old Norse compound hesta-maðr "horse-boy, groom." The word became obsolete in England but was retained in Scottish as "personal attendant of a Highland chief," in which sense Scott revived it in literary English from 1810. Sense of "obedient or unscrupulous follower" is first recorded 1839, probably based on a misunderstanding of the word as used by Scott.

cry of those leading pogroms or attacks on Jews in Europe, 1819 in reference to Jewish explusions by mobs in various German cities in that year (later called the hep-hep riots); perhaps originally the cry of a goatherd, or of a hunter urging on dogs, but popularly said at the time to be acronym of Latin Hierosolyma Est Perdita "Jerusalem is destroyed," which, as H.E.P., supposedly was emblazoned on the banners of medieval recruiters for the Crusades who drew mobs that subsequently turned on local Jewish populations.
