Prince William Augustus, Duke of Cumberland (15 April 1721 [N.S.] – 31 October 1765), was the third and youngest son of George II of Great Britain and Ireland and his wife, Caroline of Ansbach. He was Duke of Cumberland from 1726. He is best remembered for his role in putting down the Jacobite Rising at the Battle of Culloden in 1746, which made him popular in certain parts of Britain. He is often referred to by the nickname given to him by his Tory opponents: 'Butcher' Cumberland.
For much of the War of the Austrian Succession, with the assistance of John Ligonier, Cumberland commanded the main allied field army in Flanders acting in defence of the Austrian Netherlands and the Dutch Republic.
