"arms at high" position, after Orga (1808:128, Figure 3). A private's uniform in this regiment is believed
to have consisted of dark blue pants and a waistcoat fronted by a red plastron with plain brass buttons.
The white leather crossbelts are centered by a brass plate showing the cut out number "4". Attached to
the plate via a chain are the musket vent pricker and brush. The leather shako also has a brass plate with
the number "4". Infantrymen carry either a keg-shaped, one-quart canteen as mentioned by Hefter et al.
(1958), or a wooden round canteen obtained via U.S. stores prior to the war. The privates are armed with
the British India Pattern "Brown Bess" musket. The wounded man on the ground is a First Sergeant, as
noted by the fringed epaulettes on his shoulders. His damaged sword is an infantryman's briquet. In the
lower left foreground is a fragment of a saddle cloth or shabraque, with a brass number "1" signifying
the First line regiment. Illustration by Gary Zaboly.
