[3] Even though the regiment was never moved northwards beyond Newcastle, the young Marquess of Granby went to the front as a volunteer on the Duke of Cumberland's field staff and saw active service in the last stages of the insurrection, being present at the Battle of Culloden.
[4] In 1752, the Government suggested to George II that Granby be appointed colonel of the prestigious Royal Horse Guards (Blues), in order to secure the parliamentary support of his family.
[7] On 21 August, Granby arrived at Munster as second in command to Lord George Sackville, as the aged Duke of Marlborough had recently died.
[11] On 7 June 1760 he wrote to Viscount Barrington, Secretary at War, receiving a reply ten days later making enquiries as to the Hospital Board accommodation for his wounded men.
[3] Granby's success in commanding the allied cavalry required courage, control and communication, as well as skill in bringing the horse artillery to bear.
The victory at the Battle of Warburg in July 1760 over an army three times the size distinguished his generalship, and marked him as a genuine British military hero.
An interesting anecdote from 1824 also alludes to his generosity shown towards soldier’s wives: "Every person who has ever heard or read of the exploits of the late Marquis of Granby knows that his expenditure was most profuse, and his charities almost without limits.
In riding along the lines of the British forces, when he was in the chief command of them on the Continent, he used to throw down ducats to every soldier's wife who asked him for them, without discrimination.
His Lordship's generous heart could not bear to keep a person who had asked charity of him a single instant in suspense, and he in consequence drew so lavishly on the pockets of his staff, borrowing of them so hastily, that he used to forget from whom he had received these momentary loans.
In May 1765, Lord Halifax attempted to persuade George III to appoint Granby Commander-in-Chief of the Forces, in the hopes that his popularity would help quell the riot of the London silk weavers.
Worse still, a reply to Junius by his friend Sir William Draper, intended in his defence, essentially validated the charge that the hard-drinking and personable Granby was easily imposed upon by less scrupulous acquaintances.
On 9 January 1770, he announced that he had reversed himself once more on the propriety of expelling Wilkes, and shortly thereafter resigned as commander-in-chief and Master-General of the Ordnance, retaining only the colonelcy of the Blues.
This temper plunged him into difficulties, debts and distresses; and I have lived to see the first heir of a subject in the Kingdom have a miserable shifting life, attended by a levee of duns, and at last die broken-hearted.
"[19][20] He is probably best known today for being popularly supposed to have more pubs named after him than any other person — due, it is said, to his practice of setting up old soldiers of his regiment as publicans when they were too old to serve any longer.
