The Battle of Port Republic was a small but tactically significant engagement in the American Civil War that took place on June 9, 1862, in Port Republic, Virginia, along the South Fork of the Shenandoah River approximately seven miles west of Harrisonburg.
Although an isolated battle that only involved slightly more than 8,000 troops and lasted roughly five hours, its historical implications and immediate effects for General Thomas J. “Stonewall” Jackson and his 8,000-man “foot cavalry” of the Valley Army proved vital, not only for controlling and securing control of the vital resource area of the upper Shenandoah Valley for the remainder of the conflict, but also in securing much-needed supplies, intelligence, and even men that the Valley Army, by this point in their Valley Campaign badly needed.
