He was also an ally of his half-brothers the Duke of Maine and the Count of Toulouse, legitimised bastard children of Madame de Montespan and Louis XIV.

However, despite his best efforts, he was unable to win the king's favour and, after he made an error in maneuvering his troops at the battle of Ramillies, he was even dismissed from the army in 1707.

In 1711, Louis XIV promoted the marquisate of Antin into a "duché-pairie", and in 1724 d'Antin became a knight of the Ordre du Saint-Esprit.

An excellent organiser with a natural aptitude for command, he knew how to please and how to smooth out difficulties, enriching himself greatly from the Law system.

From 1722 onwards he retired more and more, that year renouncing his title of duke in favour of his grandson, and died in 1736 at his Paris Mansion in the Chaussée-d'Antin.
