In 1807, the line infantry of the Kingdom of Wurttemberg replaced the previous Rumford style helmets with a new Raupenhelm.
The Grenadier companies had an unusual version with the raupe transverse, in some ways resembling the earlier Miters of the 7 Years War and early Prussian and Russian Napoleonic armies. Here, the Grenadier company is in the front, on the right side of the line.
Infanterie Regiment #1 had yellow facings with white piping, and white metal buttons. These are once again Piano Wargamer figures by Lucas Luber.
King Frederick of Wurttemberg devoted a lot of time and money to the army of his Kingdom, and expected them to perform well on campaign and in battle.
The Army of Wurttemberg formed a small Corps in 1809, under the command of General de Division Dominique-Joseph René Vandamme. Vandamme was born in Cassel and was fluent in German. He had a nasty disposition that alienated his colleagues, and he also publicly criticized Napoleon. A talented commander otherwise, those character features were doubtless why Napoleon never appointed him to the Marshalate!
