Dragoon Regiment Orleans was owned by Louis-Philippe, duc d'Orléans, but was commanded in the field by mestre de camp lieutenant comte de Pons Saint-Maurice. Whilst dragoons in other nation's service seem, by this time, to have fought mostly mounted, in France they retained a significant dismounted role. For example at the Battle of Hastembeck, this regiment served on the right wing in a dismounted role while at the Battle of Krefeld they were mounted.
This regiment wears almost exactly the reverse colour scheme of the other Dragoon regiment I have painted - Lanquedoc.
