The engagement was short and one-sided. Lancaster's plan was to charge across a ford in the river, while the Earl of Hereford – one of the few magnates who had remained loyal to Lancaster – crossed the bridge. Hereford was killed on the bridge, his companion Roger de Clifford, 2nd Baron de Clifford was badly wounded, and this advance failed. Lancaster, meanwhile, came under such heavy archery fire that he had to call off his attack. Defections during the night, combined with royal reinforcements, forced him to surrender the next day, and on 22 March he was executed. The king was greatly pleased with Harclay's effort, and rewarded him lavishly. On 25 March, Harclay was created Earl of Carlisle, and given land worth 1000 marks a year. On 15 September, he was also made chief Warden of the Marches.
