Armand Jean d'Allonville (13 July 1732, Dommartin-le-Saint-Père, Toul diocese, Champagne – 24 January 1811, London) was a French nobleman from an old family in Beauce.
[1] During the War of the Austrian Succession, Armand entered the French army at the end of 1745 as a cornet in the régiment Lameth-Cavalerie.
He received 15 sabre cuts at the battle of Rossbach, including ten to the head, giving rise to the scar or 'balafre' which gave him his nickname.
[5] He rose to brigadier des armées du roi on 1 March 1780 and then maréchal de camp on 1 January 1784.
Before the Revolution, Armand Jean d'Allonville came to Langres, where he had lands, but D’Allonville was made maréchal de camp of the armée des émigrés, by king's brevet, dated from Blakembourg, on 15 November 1797, effective from 15 March 1794.
