Cavendish was educated at
Eton and
Clare College, Cambridge. He and his stepbrother
Gilbert Talbot went on a Grand Tour to Venice in 1570 and to Rome in 1574. In July 1582 he had some involvement with
Mary, Queen of Scots, who declined his request. Mary claimed in March 1583 that Charles Cavendish, his brother
William Cavendish, and Bess of Hardwick had tried to convince her that the
Earl of Shrewsbury was her enemy. Mary said to
William Waad that Cavendish had slandered her. Mary wrote in March 1584 that Charles Cavendish was in London, and had kept a pair of swift horses to ride to her with news of
Elizabeth I's death, the English queen being unwell at this time. He was knighted in 1583. Charles Cavendish wrote to his mother in 1587 describing life at court in London, the reception of
Arbella Stuart, and building projects including work at
Theobalds which he compared to
Chatsworth. The musician and composer
John Wilbye dedicated
The First Set of English Madrigals (London, 1598) to Cavendish who had married Margaret Kitson, a daughter of his patrons, the
Kitsons of
Hengrave. Wilbye commended Cavendish's skills as a musician. Wilbye dedicated the
Second Set to Arbella Stuart. Cavendish had a feud with the
Stanhope family over issues including a fish weir in the
River Trent. He arranged to fight a duel with
John Stanhope at
Lambeth choosing rapiers as the weapon. They came to Lambeth bridge by boat and it was discovered that Stanhope was wearing a sword-proof padded doublet. The fight was called off. In November 1599 Cavendish was shot in the backside while visiting Kirkby Hardwick, where he was repairing and extending the mansion. The house, also known as Sutton Hardwick, was finally demolished by the
Coal Board in 1966. The site is close to
Sutton Parkway railway station.
Bess of Hardwick and Arbella Stuart In December 1607, Cavendish, the
Earl of Shrewsbury and his sister,
Mary Talbot, Countess of Shrewsbury, went to
Hardwick Hall for a day to see
Bess of Hardwick. Shrewsbury wrote he "found a lady of great years, of great wealth, and of a great wit, which yet still remains".
Arbella Stuart visited Sheffield and Hardwick after the death of Bess of Hardwick in 1608. Arbella wrote from Hardwick that Charles Cavendish was a pleasant companion, "I thinck I shall many times wish my selfe set [sat] by my cousin Charles at meales". In June 1611, Mary, Countess of Shrewsbury was imprisoned in the
Tower of London for helping Arbella Stuart to escape. Cavendish wrote from Welbeck to Henry Butler, the Shrewsburys' steward at Sheffield with the encouraging news that the Countess had the comfortable "Queen's lodgings" with 3 or 4 rooms. ==Bolsover Castle==
