Major George Scott

Commander of the Light Infantry and Rangers for the Louisbourg expedition this image is the reference for the 40th image below. Scott was an advocate of cut down clothing and leather jacked caps.  ('The Leather Cap, if properly jack't and made of good Leather is intended to fend off the blow of a scalping-axe or Firelock. It is also better adapted to the Head of a Cloke than a Hatt and will keep its form'. )
