During the Seven Years' War, Clavering served in the West Indies.[1]
During the Invasion of Guadeloupe Major-General John Barrington transferred most of the soldiers from Fort Royal, Martinique, to Fort Louis on the Grande-Terre side of Guadeloupe. In March he used this as a base from which naval transport carried separate forces under Brigadiers Byam Crump and John Clavering to attack French positions around the island. The attacks were highly effective, and the French capitulated on 2 May 1759.[3]
Clavering was married twice; firstly (in 1756) he married Lady Diana West, daughter of John West, 1st Earl De La Warr. Lady Diana died in 1766. In 1772, Clavering married his cousin, Catherine Yorke.[1]
