Alistair Horne's "The Price of Glory" is brought up a lot when talking about Verdun, but many people have criticized his bashing of Joffre and Haig (the lions led by donkeys myth, which I am now just starting to learn was a myth and not actual military history of WWI generalship, but remain quite ignorant of how WWI tactics were developed and put in practice).
Are there any books other than Price of Glory that you would recommend? Or do you maybe recommend Price of Glory but take it with a grain of salt in some sections?
I also bought a few primary sources ("The War Diary of Captain Charles Delvert" & "To The Slaughterhouse" by Jean Giono), but are there any more that you would recommend? Maybe from the German side of things?
Thanks for any assistance.
