Augustus Berkeley, 4th Earl of Berkeley Augustus Berkeley, 4th Earl of Berkeley Lieutenant-Colonel Augustus Berkeley, 4th Earl of Berkeley, KT (18 February 1715 – 9 January 1755) was the son of Vice-Admiral James Berkeley, 3rd Earl of Berkeley, and the former Lady Louisa Lennox. He was made an ensign in the 1st Regiment of Foot Guards in November 1734, and succeeded his father on 17 August 1736 as 4th Earl of Berkeley, 12th Baron Berkeley and 4th Viscount Dursley. In 1737, he was created Lord Lieutenant of Gloucestershire and Constable of St. Briavel's Castle, offices which he held until his death, and was made lieutenant-colonel of
Berkeley Castle Hugh Despenser, the favourite of Edward II. Then in 1327, Edward was deposed by his wife Queen Isabella and her ally Roger Mortimer, and placed in the joint custody of Mortimer’s son-in-law, Thomas de Berkeley, and de Berkeley‘s brother-in-law, John Maltravers. They brought Edward to Berkeley Castle, and held him there for five months from April to September. During that time a band of Edward's supporters attacked, entered the castle and rescued him, only for him to be recaptured soon afterwards. It is possible that his captors then moved him around between several castles to make further rescue more difficult,
