The Earl Marshal was certainly, the Earl of Salisbury and the count of Aumale were almost certainly, included among the nobles who were present at the coronation and who next day took the oath which has been mentioned already.[702] The coronation, the oath, the Pope’s letters, taken all together, suggest that in the spring of 1220 the Council had invoked the Pope’s assistance to enhance the authority of the Crown for the special purpose of strengthening the hands of its guardians in an effort to deal with the whole question of the English castles. It is, however, very difficult to guess what, or who, can have prompted the instructions issued to the Legate by the Pope on 26th and 28th May. The information on which the letter of 26th May purports to be written is shown by the records to be erroneous. No castle belonging to the King was in the custody of either of the archbishops; only three were in the custody of any other prelate. Those three were Porchester, Winchester, and Southampton, held by Peter des Roches together with the sheriffdom of the county in which they stood. There is also no indication that either Peter or any other prelate had ever attempted, or even been (in England) accused or suspected of attempting, to usurp castles or lands belonging to the Crown, or made difficulties about restoring any such lands which may have been temporarily entrusted to him for safe keeping during the war. The second letter is equally unaccountable; for while the enforcement of the order that no man should hold more than two royal castles at once would have deprived Peter of one such wardenship, it would have deprived Hubert de Burgh of four;[703] and it would have further involved a wholesale rearrangement not only of the wardenships, but also of the sheriffdoms, throughout south-eastern England and also in the Midlands, where a still greater number of royal castles were in the hands of Falkes de Bréauté as sheriff of seven shires. It is therefore not surprising that no use was made of these two papal mandates. As no mention of them occurs in the chronicles of the time, it is most probable that they were never published; Honorius may have sent with them private instructions authorizing Pandulf to publish or suppress them at his own discretion. By the time they reached England the King’s guardians were feeling their way in more wary fashion towards the end which they had in view.
