Tony,
Best of luck with your pre-order. I do hope you receive it before you retire...
I am probably the only person on the planet who has never--and will never--read a book, article, or thesis on Waterloo or any aspect of it.
That being freely admitted, I still have an academic knee-jerk reaction to writers who claim to have discovered the truth, the real reason behind, and a stack of never-before-seen archival material to advance their theories of anything, including Waterloo.
