Lancastrians victorious at Northampton

On July 10, 1460, in the Battle of Northampton, a Yorkist army led by Richard Neville, Earl of Warwick, and the Duke of York's son, Edward, Earl of March, trounced the Lancastrian royalist forces and captured Henry VI.
Suppose the Lancastrians were victorious at Northampton.

Suppose the Lancastrians were victorious at Northampton.

The first major butterfly would be, not having the Act of Accord passed by the English Parliament on 25 October 1460.
Instead of Richard, Duke of York entering the Council Chamber and claiming the empty throne for himself and his York heirs.
Which under the Act, King Henry VI of England was to retain the crown for life but York and his heirs were to succeed, excluding Henry's son Edward of Westminster.

The secound major butterfly is for Edward, Earl of March (OTL Edward IV of England) to be killed at the battle, meaning Edward, is unable to overthrow the throne and put the Yorks on the throne.

So without the Act of Accord, we may see a temperory end to the Wars of the Roses, with the kingdom being united, under the Lancastrian flag.
With another Lancastrians victory, at the Battle of Wakefield, with Richard, Duke of York and Richard Neville, Earl of Salisbury, York in December 1460.
