As part of Frimont's brigade the Bussy Light Horse, or Jager-Regiment zu Pferde Bussy, played an important part in the battle. Consisting of 186 men in 2 squadrons, the Bussy Horse Jager regiment included many French emigres. During the battle, according to Stutterheim, the "Bussy Jager Regiment (émigré French) came on, galloped from the main road and fell into the rear of the Guard. This attack decided and ended all fighting. Many of the Guard were sobered down, the bigger part and four guns surrendered".
I was able to find very useful reference images for this unit, including Mollo and Knotel, plus Osprey.
For the figures I had a lot of choice, with most companies supplying suitable miniatures. As luck had it though, just as I was about to go looking, I got an email announcing Campaign Games Miniatures had just that day released their Austrian cavalry. They had a 12 figure unit available, so an order was placed and arrived a day or two later... not bad for coming from Barcelona.
These new figures are nicely cast, with no flash and minimal mold lines. The poses are reasonable animated, with my only issue with them being that the uniform under the raised arms looks a bit strange. Otherwise they are great, and a joy to paint. The set I bought included a standard, which probably is totally wrong for this unit, but I included it anyway. I'm really happy how these came out.
