The siege of the Tower of London was an episode of the Wars of the Roses, in which adherents of the rival Plantagenet houses of Lancaster and York were pitted against each other. In June 1460, several Yorkist nobles, who had unsuccessfully rebelled against King Henry VI the year before and had fled to Calais, invaded the south east of England at Sandwich. They enjoyed widespread support through popular discontent with the ruling court among the populace of Kent and the merchants of London, and were greeted by enthusiastic crowds when they entered London on 2 July. The Lancastrian garrison of the Tower of London, commanded by Lord Scales, opened fire indiscriminately into the surrounding streets with cannon and wildfire, causing many deaths and injuries. While most of the Yorkist army marched north into the Midlands to engage the King's Lancastrian army, 2000 men were left under the Earl of Salisbury to besiege the Tower.
