Initially the new government had little success, but in 1220, the fortunes of Henry's government began to improve. The Pope allowed Henry to be crowned for a second time, using a new set of royal regalia. The fresh coronation was intended to affirm the authority of the King; Henry promised to restore the powers of the Crown, and the barons swore that they would give back the royal castles and pay their debts to the Crown, on the threat of excommunication. Hubert, accompanied by Henry, moved into Wales to suppress Llywelyn in 1223, and in England his forces steadily reclaimed Henry's castles. The effort against the remaining recalcitrant barons came to a head in 1224 with the siege of Bedford Castle, which Henry and Hubert besieged for eight weeks; when it finally fell, almost all of the garrison were executed.
