With his cousin dead, Thomas landed at Sandwich, sending his ships to sail around Kent and up the Thames Estuary. He himself advanced over land towards London, gathering troops as he went, and received notable support from Canterbury and its mayor Nicholas Faunt. Edward meanwhile headed west to oppose the Lancastrian army advancing from the West Country. On 4 May he triumphed in the Battle of Tewkesbury, killing Edward, Prince of Wales, Edmund Beaufort, Duke of Somerset, and John Beaufort, the duke's younger brother, and capturing the Queen, Margaret of Anjou. Unaware of these events, Thomas reached Southwark, and on 14 May wrote to the city government of London, asking to be allowed to bring his men into the city. They refused, and he responded by burning Southwark.
