Early in 1322, king Edward took forces north in England to subdue his cousin Thomas, Earl of Lancaster. Lancaster was pushed further north, where he may have been hoping to join up with forces from Scotland. However on March 16, he found his way across the river Wye barred by forces of Sir Andrew Harclay. Sir Andrew used the infantry tactics which were later to prove so effective against the French at Crecy, and the rebels were defeated.
Of the rebel leaders, Humphrey de Bohun, 4th Earl of Hereford, was killed, and the rest captured. The prisoners were later convicted of treason and executed.
