In 1813 when Prussia made ready to fight in war, a massive reform was done to prevent a disaster such as 1806 in Jena&Austerlitz. Half of the army consisted of hastily trained patriotic volunteers. There were musketeers and 12 Lb'er Artillery. Cavalry consisted of Hussars, Dragoons, and finally Lancers (Uhlans) and the National Garde. The national guard is basically rich landwehr cavalry. I plan on writing more about it but for now I will post some less common illustrations. Feel free to add to the research I want to start. Past the 15th or so regiment the infantry becomes reserve and wears a less fashionable uniform.
For a complete overview, and since I'm lazy check here for pictures and sources http://befreiungskriege.wordpress.com/prussian-army-resources/
Regular Infantry was organized like this:
Fusiliers (Basically musketeers but operated with light infantry tactics, the only difference was black straps or a plume (in the 25th only) )
Reserve Infantry and Landwehr (silisian) THE BRUNSWICKER IS NOT PART OF THE PRUSSIAN ARMY
Various Landwehr types firing.
WILL ADD MORE LATER
