In response to public animosity towards King Richard's closest associates, Henry IV deprived Edward of his office of Constable of the Tower on 31 August 1399, shortly after his accession. On 20 October 1399, he was imprisoned at Windsor Castle, and on 3 November deprived of the dukedom of Aumale, but not his other titles. Edward's period of disfavour was not long-lasting, however. The King confirmed him in his offices in connection with the Channel Islands and the Isle of Wight, and by 4 December 1399 had made him a member of his council.
