When Rutland, on the death of his son Granby, would not ‘meddle with the administration of his estate’ because of the load of debt, Charles pledged himself ‘when of age ... to pay everything he owed, though he should live upon a crust from 21 to 61’.
He had steadily voted with Opposition on America; over the contractors bill, 12 Feb. 1779, was classed by Robinson as ‘contra, absent’; and again voted with Opposition on Keppel, 3 Mar., followed by the two Manners Suttons, Thoroton, and Lord Tyrconnel.
The very large division of 170 to 204 has alarmed the ministers [wrote Rockingham to Granby on 5 Mar.] ... By what I can learn very, very few indeed of the 170 have or will go out of town ... All our friends are exerting everywhere to get what numbers we possibly can for Monday. I do assure you, that your having gone into the country with a doubt on your being back by Monday[’s] business in the House of Commons, is felt and much regretted by your friends, and is even a matter of triumph among others ... you would by no means wish to please ...
Your Lordship’s absence also occasions the absence of Mr. Sutton and as I hear, also, of Mr. Thoroton, it may also of some in London ... it is not a pleasant thing, that maintaining and professing the good principles, which you do, you should nevertheless appear for a moment to be inattentive in your exertions at this most critical time.
Still, Granby absented himself, and so did his four followers—his reasons are not known.
On succeeding to the dukedom in May 1779, he supported William Pitt in Cambridge University;
He died at his post in Dublin, 24 Oct. 1787.
