Falk strengthened and held the castle into the reign of Henry III., and thence ravaged the country below the Chilterns. At first a supporter of the young king, he afterwards resisted his authority, and, at the instance of his oppressed neighbours, Henry de Braibroc was sent to Dunstable in 8th Henry III., 1224, to try their complaints, when thirty verdicts were found against the baron, and fines imposed of £100 under each of them. In revenge, Falk kidnapped the judge and lodged him a prisoner in Bedford Castle, treating him with much indignity. His wife complained to the Parliament then at Northampton, and the king ordered him to give up the judge, but in vain. Henry was probably glad of the opportunity of crushing a very turbulent subject, and appears to have lost no time in punishing the affront. In June, 1224, commenced a series of orders, issued by the king himself, and which show the greatness of his preparations for a siege, and the vigour with which he pushed them forward. On the 22nd of June, Henry was at Bedford in person, and there remained during the siege until the 19th of August, nearly two months. The preparations were both extensive and minute, and the mandates, always described as pressing, were issued to a vast number of sheriffs and other persons as far south and west as Corfe Castle and St. Briavels. They require men, money, arrears of scutage, cord, cable, iron, steel, hides, leather for slings, twine for strings, mangonels, petraries, balistæ, quarrells, stone shot, quarrymen, masons, miners, carpenters, saddlers, wagons for conveying the royal pavilions, and almonds, spice, and ginger for the royal still-room. All the smiths in Northampton who can forge quarrell bolts, or feather them when forged, are to work day and night until 4,000 are ready and despatched. Large quantities of wine from the royal stores in London, at Northampton, and elsewhere, are to be forwarded with speed to Bedford. Knights performing castle guard at Lancaster are ordered up: greyhounds are sent for for sport. The sheriff of Bedfordshire is to supply quarrymen and masons with their levers, hammers, mauls, and wedges, and everything necessary for the preparation of stone shot for the mangonels and petraries. Miners come from St. Briavels, in the Forest of Dean. Windsor supplies its master-carpenter and his mates. Cambridge sends cord and cable. Charcoal comes with the iron and steel from Gloucester, and the adjacent abbey of Newenham spares a large quantity of raw stone to be converted into shot.
