@Taco: a translation into English would be great, was thinking of it myself but it would be quite some work.

About the French vision, I found some info during my research. Siborne tried to obtain information both from French officers and the Ministry of War. They weren't very helpful. Waterloo was a quite painful memory for the French. Most accounts written by French officers take the form of a apology in which they defend themselves from blame of the defeat. In the traditional French view Napoleon is also freed from any blame. The French opinion of Wellington allies is mixed. They had the opinion that Wellingtons army was just a disorganised hodgepodge of nations. On the other side they started a campaign to persuade the Dutch to join the French cause. So the French, just as the British believed, that the Dutch fostered loyalty feelings towards them. This idea proved wrong as almost no Dutch troops crossed over.

Of course there is also the report of Victor Hugo, as motioned by others on my previous post for help.
