I have created an excel spreadsheet that randomly generates armies for the Bohemian phase of the Thirty Years war consistent with the forces described in the White Mountain rules.
Unfortunately, WordPress does not allow me to publish .xls files here. If you want a copy, drop me an email at Bozzie99@gmail.com and I’ll send it to you.
The spreadsheet allows you to set the proportion of each type of regiment that could be present in a typical Catholic/Imperial or Protestant army. It then generates a 20 regiments a side, divided into left, centre and right zones plus a reserve. This is about the right number of units to populate a typical 13 x 10 hex board. It also tells you how many blocks are each regiment and, using the underlying calculations, then tells you the real manpower so you can get a feel for the actual battle scale. The spreadsheet gives force sizes typically between 10,000 and 20,000 men.
Simon and I recently tested this and other parts of the game. This write up will follow, along with cut images of the army generator output.
