Promoted to brigade command late because of his ongoing health issues, Hunton was assigned to Lt. Gen. James Longstreet's corps, Maj. Gen. George Pickett's division, and the Army of Northern Virginia. In August 1863, Hunton formally received a promotion to brigadier general, based on his valor during the Battle of Gettysburg, particularly during Pickett's Charge in which Hunton received a leg wound. Because of his promotion, Norborne Berkeley was promoted to command the 8th Virginia, and his brother Edmund became the Lieut. Colonel, his brother William Berkeley, Major, and Charles Berkeley became the senior Captain of what then became known as the "Berkeley Regiment." After service in the defenses of Richmond in 1864 including the Battle of Malvern Hill, Gen. Hunton rejoined Pickett's division and fought at Cold Harbor and once again defended Richmond and Petersburg siege lines. In March 1865 his command (by then reduced to 1500 men) fought a delaying action at Five Forks, which turned into a rout.
