@Zack White Recently on the latest Napoleonicist episode, an accusation was levelled at Wellington for immediately betraying Blucher regarding the battle's title; as in, after meeting eachother Blucher mentions La Belle Alliance as being the perfect name for the battle, after which Wellington rides back to his despatch box and immediately ensures the battle is called Waterloo by mentioning that name.
There are multiple problems I have with this accusation. The meeting probably happened some distance south of that Inn. Also, can it be confirmed that when they both met up the naming of the battle was mentioned? From what I know it was a short meeting in which they discussed the current situation and what needs to be done (the pursuit). Another point to add is that the mention of Waterloo in the despatch is nothing out of the ordinary. He mentions it as being his current location in the top right-hand corner (as he did with all of his despatches). Waterloo was his current headquarters so there's nothing really suspicious about that as far as I'm concerned. He also mentions it in relation to where the ridge is, which in my opinion is not too egregious.
I would like to get people's thoughts on this.
Wellington was a fluent French speaker / writer, since he studied at a (private) French military school. Blücher didn't speak French, but surely someone of his staff, who translated to Wellington. So I believe, the communication at the "Belle Alliance" inn was relatively easy.
