The Battle of Bulgnéville fought on 2 July 1431 . The battle was fought between two cousins, René I d'Anjou and Antoine de Vaudémont, over partition of the Duchy of Lorraine after the death of Duke Charles II. Although René was defeated and captured, the result was reversed by diplomatic means in the years following.
Duke Charles II was determined in the absence of a son that his daughter Isabella was to inherit from him. In 1420 she was married to Rene d'Anjou, who, a year earlier, had taken over the Duchy of Bar. Charles' will was contested by his nephew, Antoine de Vaudémont, in his own lifetime, after which Charles disinherited him. Charles made attacks on Antoine's property which came to nothing, because Antoine had found a powerful ally in Philip the Good, Duke of Burgundy. After Charles' death in January 1431, Antoine renewed his fight for the duchy.
Antoine de Vaudémont had 4000 cavalry and 5000 infantry, largely Burgundian but also Picards and a small contingent of English, under the command of Antoine de Toulongeon, the Marshal of the Duke of Burgundy. Duke René had support from his brother-in-law, the French king Charles VII, who sent an army of 4000 cavalry and 6000 infantry under the command of the old soldier Arnaud Guillaume de Barbazan. Unfortunately, the French troops were inexperienced and not properly integrated. Pfalzgraf Ludwig III, brother-in-law of the deceased duke, sent 500 knights.
The Burgundian army had carried out a chevauchée into Lorraine and were withdrawing, pursued by the army of Duke René. The two forces met one kilometer south of Vaudoncourt. Vaudémont's army placed themselves on a gentle slope, with trees and a stream behind to cover their rear. The army dismounted and the horses and baggage were placed to the rear of the army. The army's archers, mainly Picards, were deployed behind stakes on the flanks and in front of the men-at-arms in the centre. The Burgundians also deployed cannons with their archers.
