In another forum it was commented there there appears to be a good bit of room for maneuver. One interesting point is the apparent room for maneuver at Rollica. Rollica was not a huge battle, but this field of battle and the troops are all scaled to represent the area they would have actually covered (depth of formation is perhaps slightly over represented). As can be seen they were not crammed in with no room for maneuver. The battlefield represents an area a bit over a mile in length over which the French had spread a mere 5 battalions.
