Richard Neville, known as the 'Kingmaker', had been a pivotal figure in the struggle for power during the War of the Roses. By aligning with Edward, Earl of March, he solidified a strong alliance aimed at dethroning Henry VI of the Lancastrian line. Their recruitment of a substantial rebel army showcased the mounting dissatisfaction with the Lancastrian leadership, marked by a series of military defeats and political missteps. Upon landing in England, they quickly began their march toward London, gathering supporters along the way who were eager to join the Yorkist cause.

As they progressed, the anticipation among the populace grew. Many saw the Yorkists as a solution to the instability that had gripped England. The march was not just a military maneuver but also a strategic bid to capture the heart of the country—its capital. The Earl of Warwick and Edward understood the importance of London, not only as a center of power but as a symbol of legitimacy and influence. Their approach was characterized by a mix of military readiness and political acumen, aiming to bolster their ranks while presenting a united front against Henry VI.

The arrival of Warwick and Edward would set off a series of events that would destabilize the Lancaster hold on the throne. Their campaign led to the pivotal battles that would ultimately reshape the English monarchy. As they entered London, they would gather more support and prepare for confrontations that were yet to come, effectively intensifying the conflicts between the houses of York and Lancaster, leading to further significant battles throughout the War of the Roses.
