I'm still deep in the woods, so apologies for any historical inaccuracies .. I remember a noble,Austrian? ,Prussian? , who raised a force of cavalry, infantry,and artillery ...fought the French and drove to the coast to regroup in England, but he had to abandon the infantry and cannon...the uniform was black with skull motifs on the jackets and hats to signify mourning for the loss of family and nation.
I did not see them listed, and with the growing number of Napoleonic sets available ...I am sure I could just paint some black, yet I am curious if the black hussars and accompanied legion has much traction here.
