George was appointed Lord Warden of the Cinque Ports and Constable of Dover Castle. These were among the highest appointments in the realm and, as usual, he committed to them with zeal. He is regularly referred to in the State Papers in his position as Warden sitting at the Warden's court at Dover. From Thomas Cromwell's point of view, George's influence as Lord Warden was a thorn in his side. On 26 November 1534, George wrote to Cromwell expressing fury that Cromwell had undermined one of his orders made as Lord Warden. Trial and execution: 1536 In 1536, Anne Boleyn miscarried a son. Her failure to provide Henry with a male heir coincided with Henry's infatuation with Jane Seymour, one of his wife's maids-of-honour. To rid himself of his wife, Henry and his chief advisor, Thomas Cromwell, devised a plot whereby Anne was accused of adultery with five men, one of whom was her brother, George. George was charged with incest with the Queen and plotting with Anne to kill the King. During a conversation with Chapuys following the Boleyns' deaths, Cromwell boasted that he had gone to a great deal of trouble arranging the plot, suggesting he did so in order to assist an alliance with Spain. Yet despite his boasts, during the same conversation he greatly praised both Anne and her brother for their "sense, wit, and courage". On 23 April 1536 George was expected to be chosen to receive the Order of the Garter, but the honour went to a known opponent of the Boleyns instead, Sir Nicholas Carew. The following day, Henry gave instructions to Cromwell to set up a special commission looking into various treasons. Anne and George were arrested on 2 May 1536, the day after the May Day joust at which George was one of the principal jousters. The four others implicated in the plot, Sir Henry Norris, Sir Francis Weston, Sir William Brereton, and Mark Smeaton were tried on Friday 12 May. Only Smeaton confessed, probably after torture, but certainly emotional pressure. Despite lack of evidence all four men were found guilty. Thomas Howard, Duke of Norfolk sat on the jury and effectively condemned his own niece by finding the men guilty. Anne was pre-judged for the earlier convictions of the men found guilty of adultery with her; therefore she stood trial before her brother. George stood trial a few hours after
