Original sentence: Edward of March, having joined with Warwick's surviving forces, advanced towards London from the west at the same time that the queen retreated northwards to Dunstable; as a result, Edward and Warwick were able to enter London with their army.Henry, claimed Edward, had forfeited his right to the crown by allowing his queen to take up arms against his rightful heirs under the Act of Accord.It was clear that Edward was no longer simply trying to free the king from bad councillors, but that his goal was to take the crown.Parliament had already accepted that Edward's victory was simply a restoration of the rightful heir to the throne.The request was quickly approved by Parliament, and Edward was unofficially crowned in an impromptu ceremony at Westminster Abbey; Edward vowed that he would not have a formal coronation until Henry VI and his wife were removed from the scene.They found considerable support there, as the city was largely Yorkist-supporting.Thomas Kempe, the Bishop of London, asked the people of London their opinion and they replied with shouts of "King Edward"
Edited sentence: Edward could no longer claim simply to be trying to free the king from bad councillors; it had become a battle for the crown.Edward needed authority, and this seemed forthcoming when Thomas Kempe, the Bishop of London, asked the people of London their opinion and they replied with shouts of "King Edward".He also announced that Henry had forfeited his right to the crown by allowing his queen to take up arms against his rightful heirs under the Act of Accord, though it was being widely argued that Edward's victory was simply a restoration of the rightful heir to the throne, which neither Henry nor his Lancastrian predecessors had been.Meanwhile, Edward of March advanced towards London from the west where he had joined forces with Warwick's surviving forces.Parliament had accepted this argument the year before.They were welcomed with enthusiasm, money and supplies by the largely Yorkist-supporting city.This coincided with the northward retreat by the queen to Dunstable, allowing Edward and Warwick to enter London with their army.This was quickly confirmed by Parliament, and Edward was unofficially crowned in a hastily arranged ceremony at Westminster Abbey amidst much jubilation, although Edward vowed he would not have a formal coronation until Henry and Margaret were executed or exiled
