After fighting under former U.S. Army officer and Franklin County delegate Col. Jubal Early at the First Manassas, the 24th Virginia was assigned to Brigades in the Army of Northern Virginia often colloquially referred to by the commander's surname--first commanded by Early (hence "Early's Brigade"), then after his promotion, by future CSA General and Virginia state senator W. R. Terry (hence "Terry's Brigade"), who was temporarily disabled by a wound at the Battle of Williamsburg and temporarily replaced as brigade commander by future CSA General and later Virginia Governor James L. Kemper (hence "Kemper's Brigade").
