François-Hubert Drouais. Le Comte de Vaudreuil, 1758. Oil on canvas. The National Gallery, London.
"They [Letters by Vaudreuil] prove him to have been a man of sound judgment and a model courtier. He saw that any attempt to induce foreign Powers to interfere on behalf of Louis XVI, at least during the Constituent Assembly, would only do mischief to the Royal cause. He was ready enough to oppose the Revolution, but he would not, as so many of the emigres did, join the armies of the enemy in fighting against France. He did much to restrain the fiery temper of the Comte d'Artois. His prudent and respectful advice to the prince concerning his passion for Madame de Polastron was the means of avoiding much scandal."
