I'm actually working on a small scenario for a pleasant evening with beer and brezeln and a game of HoW.
I thought that 4 units of cavalry per side are the least I wish to have. Now it would be possible to put all units under one single command (Ligonier) or to split them in 2 brigades, one of hanoverian horse under command of general Hammerstein and a second under Ligonier (although in fact he commanded the whole allied cavalry wing and not a brigade only).
In the rules brigades are normal. But to have 2 allied brigades of cavalry would mean that there would be 3 brigades of French horse. Hm. A lot of rolling dice... What do you think about it?
Es marschierten drei Regimenter wohl über den Rhein...
I think if you are talking 28mm then that sounds reasonable. I'd say have each brigade commanded separately. Surely there is/was a (British?) brigade commander under Ligonier. Should have two brigadiers and an over-all commander.
I am starting to organize my command system. I'm working on having an army commander, right and left wing infantry commanders (and perhaps a center commander for the largest (French) army,) and at least one commander of cavalry, and perhaps two. Each commander will have an ADC, with the army commander having three. The army commander must write commands and have an ADC "carry" the command to the appropriate officer. The commander on the spot will then carry out the orders according to his whim. If he wants to let the army commander know something, he will send his ADC (or go himself.) No more instant telepathy.
Of course I'm talking about 15mm, where each side has 8-10 cavalry regiments and the French (for example) have 7 4-battalion brigades of infantry.
