Edward is unable to rest after the battle.
Lancastrians under Jasper Tudor are still active in Wales, and there is an ineffective rising in the North.
Edward goes to Coventry in the Midlands to make dispositions against the northern and Welsh Lancastrians, and give his army three days' rest.
The most dangerous Lancastrian force however, is that commanded by the Bastard of Fauconberg.
As anticipated, he has landed at Sandwich and rapidly recruited a force from among the pro-Neville Kentishmen.
Together with exiled Lancastrians and freebooters from several countries, his army may number sixteen thousand or even seventeen thousand in total.
He attacks London from the south on May 14.
His men burn part of the suburb of Southwark, but are beaten back at London Bridge.
The next day, they attack Aldgate and Bishopsgate from the east.
The garrison of the Tower of London, led by Earl Rivers, Queen Elizabeth's brother, who had been injured at Barnet, repulses them.
Citizens defending their property undoubtedly play a major role.
Had Fauconberg succeeded in capturing the city, he might also have captured Edward's wife and their children and released King Henry from the Tower.
However, on hearing that Edward's army is approaching, he retreats to Sandwich.
Like Margaret, he appears to be dispirited by the news of Tewkesbury and the Prince's death, and later rather tamely surrenders himself and his ships.
He will be executed five months later after attempting to escape from custody.
Edward, on his way to suppress Fauconberg and the Kentish rebels, on May 21 passes through London in triumph with the captive Queen Margaret beside him in a chariot.
King Henry VI dies in the Tower of London this night, at the hands of or by the order of Richard of Gloucester according to several contemporary accounts.
It is announced in public that he had died "of pure displeasure and melancholy", but few believe this.
