Imperial Footmen
I have so far found very little information on the footmen of the imperial entourage. What I have written here is based only on observation of several period photographs and one colour illustration of their home uniform (printed in "The Kaiser's Warlords" by R Pawly and P Courcelle, Osprey Elite 97).
The collar and plain turn-back cuffs of the khaki tunic were black for officers and senior NCOs and khaki for junior NCOs and other ranks, both were edged in the same lace as worn on their home uniforms. This lace was white edged in red and back and had black Prussian eagles along its length. They wore no shoulder straps. Some photographs show footmen with plain khaki trousers or riding breeches, and some show a broad white stripe on the outside seem.
Their tropical helmets appear to have been from a different manufacturer to the helmets worn by the staff and Leibgendarmerie. They may have been bought from several different sources. Some appear rounder than the Leibgendarmerie helmets, some appear similar to British army helmets of the period (see photographs below). The tropical helmets of the footmen had no spike or eagle on the front, but from period photographs it appears that some members had a small cockade at the front to replace the two on the sides worn by the Leibgendarmerie and general officers. Officers had yellow metallic cords around the hatband of the tropical helmet. The side cap appears in period photographs to have been plain khaki without cockades.
