as recalled, ostensibly because he married the widow Anne Duvivier (1730–1798), also known as de Viviers; they previously lived together while she was the ambassador's mistress. In addition, Gravier married her without seeking the King's consent. She was the widow of Francesco Testa (c. 1720-1754), a merchant member of one of the oldest and distinguished Latin families of Péra, originally from Genoa. She was widowed at the age of 24, before she met Charles Gravier, and they had two daughters together. The painter Antoine de Favray who was living in Istanbul at this time painted Charles Gravier's wife, Annette Duvivier, Comtesse de Vergennes, in an oriental costume, sitting on a divan, shortly before they married. However, Charles Gravier was more probably recalled because the Duc de Choiseul thought him not competent to provoke a war between Imperial Russia and the Ottomans, which Choiseul hoped for.

Although he thought the strategy unwise, Vergennes continuously advocated war in Constantinople by trying to convince the Ottomans that war was the only way to check Russia's rising power. Vergennes's marriage had taken place without the King's consent, which was a requirement for French ambassadors. In France Vergennes encountered strong disapproval of his marriage and was aware that he returned home in disgrace.

It eventually ended in a decisive victory for the Russians, who gained new territory, and further eroded Ottoman power. Despite his opposition to the policy, Vergennes still took credit in France for having fulfilled his orders to provoke a war. During this period Vergennes and Choiseul deve
