It was fun trying to spot them. Here are a few. Excuse the poor images.
The pictures below show short scenes that have been added for Ligny and when the Prussians advance at Waterloo. I have heard that the original film had more scenes covering Plancenoit. Shame they were cut.
This last one looks like a mock up board of a scene and includes this dialogue.
