Keep an eye on your troops. Last battle I had two corps decide to retreat. If they get off the map, you probably can't get them back. I had artillery from both corps get away from me before I was able to give the corps commanders orders to form a defensive line.
The Austrian corps commander still had 10,000 men! My orders to him didn't need a translator, either. After they'd returned I was able to send them forward.
I even saw a French corps retreating off the map. The Imperial Guard, no less. I have no idea why they left other than the fact that they were almost the only French troops left on the map and two infantry units were in full rout.
They were in the town, but not defensively in the buildings. I had one unit march into town, meet the Guard, the guard routed and my men got into the buildings... I'm not sure the exact order of what happened, if the guard routed first or my troops garrisoned the building first.
The battle ended abruptly when I was pulling my camera back to see what my men were doing in the town and the game locked up. Still pulled a victory out of it.
