This was the turning point of the battle. The Lancastrians were disheartened at the arrival of fresh foes. The fighting continued until late in the {33} afternoon, and the slaughter was prodigious, but gradually the Lancastrian left wing was doubled up on the centre; the confusion increased, and there was a complete rout. Lord Dacre had fallen early in the day. He was killed by a boy who shot him from a 'bur' tree,[5] when he had unclasped his helmet to drink a cup of wine. The lad thus avenged his father's death, who had been slain by the northern baron. Lord Caere's friends, Sir John and Sir Thomas Crakenthorpe, from the banks of the Eden, fell with him. The Earl of Northumberland, Sir Richard Percy, Lord Welles, and Sir Andrew Trollope were slain in the thick of the fight, with many more. The retreat to the eastward being cut off by the Duke of Norfolk, the defeated army fled down the steep slopes into the valley of the Cock closely pursued. The well-mounted noblemen, Somerset and Exeter, Devonshire and Wiltshire, Beaumont, Hungerford, and FitzHugh, with many knights, effected their escape. But the footmen were cut down by hundreds in the pursuit. The little Cock beck is not very wide, but it is deep, and many fugitives were drowned in it. The country people declared that the pursuers crossed the brook on dead bodies, and that the river Wharfe was coloured with blood. The Croyland monk relates that the blood of the slain lay caked with snow, which then covered the ground, and that afterwards, when the snow melted, the blood flowed along the furrows and ditches for a distance of two or three miles. The chase continued all night and part of next day. Fully 10,000 were stated to have been wounded or {34} made prisoners, and Polydore Virgil says that some were cured and some died. This disposes of the statement of Hall, which is adopted by modern writers, that no quarter was given. Edward always gave quarter to the men and junior officers of a defeated army. The fugitive nobles only had time to ride through York, calling upon Henry and Margaret, with their child, to mount and ride as hard as their horses would carry them. Away they went out of Bootham, and through the dark forest of Galtres, to take refuge in Scotland. King Edward advanced to York on Monday, March 30, 1461, where he was received with great solemnity by the mayor and commons of the city, in procession. They obtained grace through the intercession of Lords Montagu and Berners. The heads of the Duke of York, the Earl of Rutland, and the Earl of Salisbury were removed from the gates of York, and placed with the bodies at Pomfret, preparatory to the subsequent magnificent obsequies at Fotheringhay and Bisham.
