The Prussian 6th Uhlans will join the 3rd Silesian Landwehr Uhlans to form the first allied cavalry regiment.
This unit was formed out of Uhlans from Lutzow's Freikorps and Uhlans from the Bremen Volunteers. Note the picture above is from 1813. By the time of the Hundred Days campaign, they were black over red as pictured below.
There are some small differences between the Lutzow's Freikorps uniform/equipment (black collars piped in red, and black over red lance pinions) and those of the Bremen Volunteers (red collars, and red over white pinions).
Pictured below are the Der Kriegspielers Prussian Uhlans as they appeared upon arrival at camp.
The first squadron on the left has already been painted as the 3rd Silesian Landwehr Uhlans. See the prior post here. The middle squadron will now become the Prussian 6th Uhlans. I will have to decide what to do with the other 4 figures. Time to get busy painting!
