As for the Austrian Uhlans, as far as I remember there were only four regiments (although with up to six to eight squadrons) but they were mostly deployed in the Italian theatre of war. The Schwarzenberg Uhlans saw action at Aspern and Wagram, Hanau and La Rothiere). I couldn't find much about the others. Merveldt and Carl-Ludwig Uhlans were with Bellegarde in Italy and one or both may have fought at the battle of the Mincio River in 1814, but I'm not an expert in the 1814 campaign or the campaigns in Italy, so perhaps someone else can offer more information.

If the majority of WSS sets do get released in this next batch, it will be a very expensive year!
