 Margaret Pole was held in the Tower of London for two and a half years under severe conditions; she, her grandson (Montagu's son), and Exeter's son were held together and supported by the King.In 1540, Cromwell himself fell from favour and was himself executed and attainted.She was finally executed in 1541, protesting her innocence until the last – a highly publicised case which was considered a grave miscarriage of justice both at the time and later.
