Chevy Chase
Chevy Chase, a name sometimes applied to the celebrated border battle - Otterburn (q.v.) - between Percy and Douglas, the memory of which has been preserved to modern times by the stirring ballad of "Chevy Chase," one edition of which may be found in the Percy Reliques, though a more modernised form is the most widely known. The word "chevy" or "chivvy," well-known to every boy, is said to be of gipsy origin, and to signify to goad or chase.
