This is a large scenario and I had several players who were new to the rules. While they all learned quickly we ran out of time before the battle came to a full conclusion. There were several charges, a few units wavering from casualties, but all in all both armies still had a lot of fight left in them. Per the scenario the British rear guard, holding even or slightly ahead in casualties and army cohesion, earned a minor victory, holding the field and protecting their line of march.
I'll probably be making some adjustments to the scenario and game system to further speed play in order to bring larger games like this to a conclusion in 3-4 hours.
