Yesterday someone (I think it was Art Pendragon) stated that he had amassed data on this topic and was going to publish it, but would not disclose his sources before that event.
I am intrigued; this topic has been kicked around for weeks now, but no-one - not even KK - has turned up with a source.
So, what are these documents on French Napoleon artillery doctrine? Are they published army regulations? Letters? Memoires?
