United States Army officer rank insignia had silver eagles on gold epaulettes. No insignia existed yet for lieutenant colonels, majors, captains, and lieutenants—the length and size of the fringe showing the difference of grade.

At that time, lieutenant colonels and majors were authorized leaves, captains were authorized two bars, and first lieutenants were authorized one bar on the shoulder straps.
