This success partially restored his reputation and in 1681 he supervised the siege of the Fortress of Luxembourg, withdrawing after France annexed Strasbourg before capturing it during the War of the Reunions in 1684. This was his final military action; he died in Paris on 3 February 1687, ten days before his brother Charles on 13th. De Créquy and his wife were buried in the church attached to the convent of Saint-Honoré in Paris, demolished in 1816. Their memorial was designed by Charles Le Brun and executed by Antoine Coysevox; when the Jacobin club took over the church during the French Revolution, this was moved to the Church of Saint-Roch, where it can be seen today.
