Tonight I had the best experience so far. Commanded both sides, moved one corps on each side to form defence lines close to each other and pulled the rest back. Both Corps began fighting and for the first time I saw several infantry regiments engaged at the same time, with firefights, marching and counter-marching, units advancing and falling back, forming square as cavalry approached, and even a successful charge by some lancers that resulted in the enemy infantry (who for some reason did not form square but were in a loose line/skirmish formation) putting up their hands and slowly trudging away under escort. Some units made the old mistake of advancing against artillery, only to fall back in disarray, but they did not go into escape mode but regrouped later on. Some of the cavalry from the other Corps came up and joined in later. I gave no other orders at all (apart from trying to make the artillery on side fire on the artillery on the other, so as to see if the infantry would advance more freely) and just watched a really nice representation of a Napeolonic battle.
JMM, I think at last I can see what LG is about. I'm more excited now than just before the demo was released.
