During this time, Hinchingbrooke was one of the infamous Mohocks, and was arrested for assaulting a watchman in 1712. He became colonel of the 37th Regiment of Foot in 1717.
In March 1722, he was named Lord Lieutenant of Huntingdonshire and was returned as Member of Parliament for Huntingdonshire in April.

In 1713, he was elected to the House of Commons as Member of Parliament for Huntingdon, for which he served until 1722.
