Battle of Neerwinden
His mother, Charlotte de L'Aubespine, daughter of François, marquis de Hauterive by his wife, Eléonore de Volvire, marquise de Ruffec, descended from a distinguished family, noble since at least the time of Francis I. She was a formidable woman whose word was law in the family, and became more so in extreme old age. Her son Louis, of whom Louis XIV and Queen Marie-Thérèse were godparents, was well-educated, largely by her. After further tuition from the Jesuits, he joined the "Mousquetaires gris" in 1692, serving at the Siege of Namur and at the Battle of Neerwinden. Then he embarked upon his life's mission by pronouncing upon the precedence among French peers, much against the orders and interests of François-Henri de Montmorency, duc de Luxembourg, his victorious general.
