The only marshal executed in 1815 by Louis XVIII. At Waterloo, he ferociously charged the Allies after promising Louis XVIII to bring back Napoleon in an iron cage. Napoleon would say: "Ney is the bravest of men, and therein lies the limit of his faculties." ALS in French, signed 'Ney,' one page both sides, 8 x 11.5, 1813. Letter to Marshall Berthier, signed at the conclusion in black ink. In fine condition, with several small notations, a few wrinkles and creases and clear legible text. RRAuction COA.
