Why did Cornwallis move his troops to Virginia in 1781?

Cornwallis moved his troops to Virginia in 1781 to secure a stronghold in the southern colonies and to cut off American supply lines. The British aimed to consolidate their control after earlier successes in the South, hoping to recruit Loyalists and disrupt Patriot activities. Additionally, Virginia was strategically important for its resources and position, making it a focal point for British military efforts. This move ultimately led to the decisive Siege of Yorktown, where Cornwallis was trapped and forced to surrender.
