Before everybody deserted when they realized all the first rate equipment went to the regular Musketeers battalions
We quite like wearing no shoes and sometimes having to use pikes.
Landwehr were the hard workers a.k.a. the farmers of the regions, they weren't equip well but they knew the land like the back of their hands
especially on the campaign in France in 1814 and the Belgium campaign in 1815. Those would have been some well traveled farmers if they knew them like the back of their hands.
I'm sure the musketeer and fusilier battalions had as many farmers as the landwehr battalions sence Prussia was a primarily agricultural state,
