Using the Nafziger trilogy on 1813 and also the ESR volume on 1813 We Shall Meet in Vienna I have determined totals of units that will be needed to fight various battles of 1813.
1813 Campaign Project
I have not extended to Leipzig as there is no way I could get that on a table because of ground scale. When I come to fight Leipzig I will break it down into the various action. In preparation for that I expect most of the units I need will already have been painted - but will work out any additional / special allied units that are required.
For the foot the boxes are battalions, squadrons for the cavalry and batteries for the guns.
