D'Espèrey, it turns out, was a staunch Catholic, which made him an unattractive option for the French government.Foch IOTL was heavily criticised for his wasteful conduct at the Somme, but maybe ITTL his heroics would be played up in the light of the failure at Verdun. D'Esperey at the time was heading Army Group East, right? There wasn't much action there, and without many merits, he might not be considered for the position at the time. What do you think?
Foch's career likely depends on how the Somme goes, which will do better ITTL.
