Reading Chandler in "The Art of War in the Age of Malborough" i find many interesting ideas.
Concering the game engine and artillery i should prefer that OOBs for 1700-1763 would use regimental guns instead of artillery batteries or maybe just one artillery battery (not a reserve corp, just one unit) to help bombing a village; this, i believe, to portrait the dispersion of guns during the XVIII century warfare.
