they become domiciled, so that even when a voyaging sovereign finds personal attendance of officers or councilors indispensable, 8 the English headquarters will be maintained. The employment in imperial affairs of these agencies, which through the King were part of the ordinary machinery of the realm, and to that extent involved in domestic constitutional struggles, was to prove significant in many ways. In the first place, a certain community of procedure at the top level became inevitable. In the second place, a considerable degree of continuity of administrative tradition was assured. And finally, some definition of relationships had to be made as a matter of English law. It is impossible to examine Gascon rolls, the mass of documents relating to Ireland, or the slimmer bulk bearing on the Channel Islands, without an appreciation of the chains which can be forged by the use of nearly identical forms for the dispatch of affairs circumstanced as differently as those of Dublin, Bordeaux, and Jersey. All these far places felt the impress of what we have come to regard as distinctively English instruments. The effect of these inanimate things is enhanced by the employment throughout generations of a floating bureaucracy. 9 One who serves as warden of the Channel Islands may later be seneschal in Gascony. Such a seneschal may be moved to serve in Wales, and may live his last days as constable of some English castle. On less exalted levels, functionaries will move from the Exchequer to the constableship of Bordeaux and next serve on commission for the Channel Islands, and some 8 Thus, on one Gascon expedition Edward I took along his Chancellor, half the Chancery, and half his council, Lodge, Gascony under English Rule, 56. Henry IV took some of his officers and part of his council on campaigns, Baldwin, The King's Council in England during the Middle Ages, 151.

F. Tout (1925), 291. 9 For example, Drogo de Barentin (-(-1265?) was three times Seneschal of Gascony, he was Warden and Sub-warden of the Channel Islands, proctor at the papal curia, and finally Keeper of Windsor Castle (cf. 1 Bemont, Roles Gascons [Collection des documents inedits sur I'histoire de France] , Suppl., cxiv; Le Patourel, Medieval Administration of the Channel Islands [1937] 123; Close Rolls 1237-42, 165 Calendar of Patent Rolls 1258-66, 300). John de Grey was Justice of Chester, Seneschal of Gascony, Warden of the Marches of Wales, Constable of Hereford, and Sheriff of Hereford (Bemont, op. cit. cxix, Calendar of Patent Rolls 1232-47, 467-68; ibid., 12.47-58, 553, 638; ibid., 1258- 66, 163. John Havering was Sheriff of Southampton, Deputy justice of North Wales, Seneschal of Gascony, back as Justice of all Wales, again Seneschal of Gascony (Carte, Catalogue des Rolles Gascons [1743], 27, Calendar of Patent Rolls 1272—81, 284, ibid., 1292—1301, 146, 502 Tout, Place of Edward 11, 349). Oliver d'lngham (-(-1344) was governor of Ellesmere Castle, Justice of Chester, Warden of castles of Marlborough and Devizes, Seneschal of Gascony (Dictionary of National Biography, s.n.). The tendency to use experienced administrators is still seen at the end of the fourteenth century, as in the case of John Stanley who served in his youth in Aquitaine, was Deputy in Ireland, later Lieutenant, served in the Welsh Marches, was Constable of Windsor Castle, and later again Lieutenant of Ireland (cf. Dictionary of National Biography, s.n. Thomas Stanley).
