Fort Harrison, later renamed Fort Burnham, was an important component of the Confederate defenses of Richmond during the American Civil War. Named after Lieutenant William Harrison, a Confederate engineer, it was the largest in the series of fortifications that extended from New Market Road to the James River that also included Forts Brady, Hoke, Johnson, Gregg, and Gilmer. These earthworks were designed to protect the strategically important Chaffin's Bluff on the James.
