Learning of the encounter, Edward led the main Yorkist army to the bridge and was forced into a gruelling battle: although the Yorkists were superior in numbers, the narrow bridge was a bottleneck, forcing them to confront Clifford's men on equal terms. Edward sent Fauconberg and his horsemen to ford the river at Castleford, which should have been guarded by Henry, Earl of Northumberland, but he arrived late, by which time the Yorkists had crossed the ford and were heading to attack the Lancastrians at Ferrybridge from the flank. The Lancastrians retreated but were chased to Dinting Dale, where they were all killed, Clifford being slain by an arrow to his throat. Having cleared the vicinity of enemy forces, the Yorkists repaired the bridge and pressed onwards to camp overnight at Sherburn-in-Elmet. The Lancastrian army marched to Tadcaster, about north of Towton, and made camp. As dawn broke the two rival armies struck camp under dark skies and strong winds. Although it was Palm Sunday, a day of holy significance to Christians, the forces prepared for battle and a few documents named the engagement the Battle of "Palme Sonday Felde" but the name did not gain wide acceptance. Popular opinion favoured naming the battle after the village of Towton because of its proximity and it being the most prominent in the area.
