Granby returned to England as a hero: a painting by Edward Penny, "The Marquess of Granby Relieving a Sick Soldier", showed him acting as a man of charity rather than as a soldier and this assured his appeal to the people. He sought to steer a path independent of party politics but supported the Treaty of Paris. He trusted George Grenville who promptly appointed him Master-General of the Ordnance under his ministry on 14 May 1763. Granby was also made Lord Lieutenant of Derbyshire on 21 February 1764.
