[1] After John's death, Albemarle supported the new king, Henry III, fighting in the siege of Mountsorrel and at the Battle of Lincoln.
His real object was to revive the independent power of the feudal barons, and he co-operated to this end with Falkes de Breauté and other foreign adventurers established in the country by John.
This brought him into conflict with the great justiciar, Hubert de Burgh, who was effectively regent.
[2] In 1220 matters were brought to a crisis by his refusal to surrender the two royal castles of Rockingham and Sauvey of which he had been made constable in 1216.
The capture of his Castle of Bytham broke his power; he sought sanctuary and, at Pandulph's intercession, was pardoned on condition of going for six years to the Holy Land.
A reconciliation was again patched up; but it was not until the fall of Falkes de Breauté that Albemarle finally settled down as an English noble.
