Madelin thanks Barrère for his “vote” and reports Weygand’s assessment of Mangin, which he compares with that of Foch, evoking the famous counterattack on the Matz (June 1918), the first French offensive counterstroke after the German assaults of spring. The admission reported by Foch is extraordinarily powerful. “That man, at such a moment, was the only one I could trust.” Precious documentation on the internal relations of the high command and on the perception, a few years later, of Mangin’s strategy—a controversial but central figure of the 1914–18 war.
Letter written from La Mouille, Raon-l'Étape, where Madelin stayed regularly. A first-rate piece for a collector of the Great War, for diplomatic history, or for a collection centered on Foch, Weygand, or Mangin. Condition: very well preserved, fresh ink, dense and perfectly legible handwriting.
