Baden infantry ambushed (Franco-Prussian War)

This is a perhaps fictionnal skirmish that would have took place in the Vosges (1871) between a detatchment of Baden infantry (fighting for Prussia) and Republicans Franc-Tireurs (perhaps Garibaldians?). The uniforms are quite similar to the Prussian ones, except for the helmet plate (which features the arms of Baden instead of Prussia) and the leather gear (which is black instead of white).
The officers are shot first, then a ranged skirmish would follow, the Franc-Tireurs would have fallen back at some point.
