As I mentioned in the Archduke Charles thread, there was very little material in English on the 1796 campaign in Germany - just Phipps: Armies of the First French Republic Vol3 and a few brief pages in EB Hamley: Operational Art (1865). This has been enhanced by Nafziger’s translations of Jomini and Jourdan’s memoirs.
So, I was thinking that the position is somewhat better for his other less well-known campaign of 1799. The main work is Shadwell: Mountain Warfare (1875) which also draws heavily on Jomini. Then there is also material in Phipps VolV on the Second Coalition and Duffy: Eagles over the Alps for Switzerland, together with several articles in the old First Empire magazine. To that, we will apparently be able to add Clausewitz’s work on the year when the man himself was away and he considers the fighting on both sides of the Alps. It is where that claim that Charles “took the means for the end and the end for means” comes from - and it is repeated by Rothenberg, but that is for another thread when this translation, again by the university of Kansas Press comes out.
This is now due out on 30th December in UK - Nice for lockdown and being trapped with the rellies! If you are in UK, buy from Hive as they are good people (unlike a certain warehouse operation known to treat its staff badly) and they are running a 10% off this week.
