So where from here? I've decided to raise 4 x 24 man Regiments, in 2 brigades of 2. I gather that a full division would have had 8 regiments; phew.
24 man units may be a bit unwieldy on the table, but they will look the DBs, and would be around the size of a regiment at full strength, in 1:20 scale.. I also need a load more dismounted dragoons. It's all in hand... but may take a while because I'm seriously overspent and need to cut back. Also I need to finish way more infantry before I can game with the army.
