These rolls record letters patent and close, writs, mandates and other instruments passing under the great seal and relating to the Duchy of Normandy while it was under the dominion of the English crown before 1204 and during the reign of Henry V, 1417-1422.
The series also includes chirographs, concords and other documents executed in the Norman Exchequer at Caen, as well as documents of a diplomatic character, including treaties between the kings of England and the dukes of Brittany and of Burgundy.
The rolls of John's reign are similar in form, language and writing to the close rolls and other rolls of the same period. Those of the reign of Henry V consist principally of letters of safe-conduct and protection, grants and confirmations of their estates to such as voluntarily surrendered to him or to his commanders, and restitutions of their temporalities to such convents as recognized his authority. In addition, the rolls include grants to Henry's followers of the castles and estates of such Normans as were slain or remained in open rebellion, and of grants of offices, commissions of array and presentations to ecclesiastical benefices. A considerable number of the letters concern grants in England.
