On Jones's advice, Monroe returned to Williamsburg to study law, becoming a protege of Virginia Governor Thomas Jefferson.[7]
With the British increasingly focusing their operations in the Southern colonies, the Virginians moved the capital to the more defensible city of Richmond, and Monroe accompanied Jefferson to the new capital. As governor of Virginia, Jefferson held command over its militia, and made Monroe a colonel. Monroe established a messenger network to coordinate with the Continental Army and other state militias. Still unable to raise an army due to a lack of interested recruits, Monroe traveled to his home in King George County, and thus was not present for the British raid of Richmond. As both the Continental Army and the Virginia militia had an abundance of officers, Monroe did not serve during the Yorktown campaign, and, much to his frustration, did not take part in the Siege of Yorktown.[8] Although Andrew Jackson served as a courier in a militia unit at age 13, Monroe is regarded as the last U.S. president who was a Revolutionary War veteran, since he served as an officer of the Continental Army and took part in combat.
