In the 26th year of Henry III, Alan had a military summons to attend the King into France, and in ten years afterwards he had the whole county of Chester and all North Wales placed under his government. In the 45th year of the same reign he obtained a charter for a weekly market at Ashby-La-Zouche, in Leicestershire, and for two fairs in the year at Swavesey.
About the same time he was constituted warden of all the King's forests south of Trent, as also Sheriff of Northamptonshire. In the 46th year of Henry III, he was made Justice Itinerant for the counties of Southampton, Buckingham, and Northampton. Upon the arbitration made by Louis, King of France, between Henry III and the barons, he was one of the sureties on the behalf of the King. In three years afterwards he was constituted Constable of the Tower of London, and Governor of the castle at Northampton.
He was violently assaulted in Westminster Hall, in 1268, by John, Earl of Warren and Surrey, upon occasion of a dispute between them regarding some landed property, and with his son, Roger, who happened to be with him, severely wounded.
