Digby,
With all due respect to the author and publisher of the new volume under discussion, I would probably want to view before purchase (from the blurb).
BTW, I have all of your books covering the European theatre (with the exception of this volume on the Swiss)
Which, if to the standard set in your Armies of 1812, will be an excellent work.
I also have in my meagre collection, providing an indication of the length of time I've been interested, a copy of the following from when it was first published:
ARMIES OF 1812: VOL. 1 - THE FRENCH ARMY INCLUDING FOREIGN REGIMENTS IN FRENCH SERVICE AND THE CONFEDERATION OF THE RHINE
Which is also an excellent work.
Best wishes
A
