St Alban's had been dispersed and this would require re-mustering. It is likely that—since he died only a few months later—Mowbray was too ill to keep up with the main Yorkist force. At Pontefract Mowbray transferred command to Howard, knowing that time was of the essence for the Yorkists and while he was with them, his soldiers could only march as quickly as he could. If Mowbray was ill, then it is unlikely that he fought personally; Boardman observed that "a sick man would never have survived such a strength-sapping ordeal, especially a noble in armour-plate." If his contingent was tasked with bringing up Yorkist artillery, which would have further slowed them down and they may have abandoned armoury en route to increase their speed. Mowbray arrived late but at a crucial point of the battle. His prolonged absence after a day's bitter fighting must have been a worry for the Yorkists, especially as they may have thought him up to a day's march away. Mowbray's absence presented an acute problem for them; Philip A. Haigh describes them, by four o'clock in the afternoon, as doomed without him. There must have been much messaging between Edward and Mowbray throughout the day, but battle fatigue had almost certainly set in on both sides by the time Mowbray's troops arrived on the eastern edge of the battlefield. A contemporary chronicler described the situation thus Mowbray launched a decisive attack on the Lancastrian flank, turning them left. His arrival both reinvigorated the Yorkist army and crushed Lancastrian morale with his surprise attack and led rapidly to a Lancastrian rout to give the victory to Edward IV. Under the Yorkists The Earl Marshals played an important role in coronations. Like his predecessors, as Earl Marshal Mowbray officiated the coronation of Edward IV on 28 June 1461. Within two months he received several lucrative offices. Public order was a problem from the beginning of the King's reign, and East Anglia was no exception. Mobs rampaged during that year's parliamentary elections. Norfolk may have encouraged this; he is certainly a candidate for ordering the murder of coroner Thomas Denys that August. Even though Mowbray supported the Yorkist regime, he met with strong opposition from the East Anglian gentry in the first year of the reign. This was despite the support of the King, and the backing of John Howard in the shires. Howard was by now
