It is anecdotical but I want to know if the Marshalls of the Empire appointed by Napoleon got well along or if they could hardly tolerate each other.
I'm specially interested in Lannes, Davout, Desaix, Masséna, Murat, Ney and Soult.
I already know - please, correct me if I'm wrong - that Murat wasn't very much appreciated by Davout, Lannes or Ney. That Ney and Soult hated each other after Spain. That Desaix and Davout were friendly, and that Masséna refused to sentence Ney to death after the Hundred Days.
If all of the above is correct, is there anything else worth mentioning - relationship wise - among these seven Marshalls of the Empire?
