John Manners, Marquis of Granby, was the eldest son of the third Duke of Rutland. He was a popular hero of the 'Seven Years' War (1756-63) making a name for himself at the Battle of Warburg in 1760.
Here he led a spectacularly successful cavalry charge against the French, during which, it is said, his wig blew off. For some time afterwards, the popular term for being enthusiastic was 'going at it bald-headed'.
In 1766, Granby was appointed Commander in Chief, but political enemies ruined him and he died in Scarborough in 1770 owing £37,000.
The reason the Marquis was loved by his men was that he was seriously concerned for their welfare, unusual for a successful military man of his time.
After the seven year war he set up his disabled, non-commissioned officers as publicans in Inns throughout the country so that none should starve. It's said that this gesture, more than any other, brought the Marquis into such appalling debt.
