The First Line of Defense: The Union Skirmish Line

After sunset on September 14, 1862, the Confederate cannons across the road on School House Ridge vanished in the darkness. The features of the landscape began to blur as the shell-shocked Union soldiers on Bolivar Heights wondered if they could survive another day of artillery bombardment. The Union troops could not rest until tomorrow, however, because General “Stonewall” Jackson’s Confederate Army might charge over School House Ridge at any moment. To guard against such an attack, the Union command established a human alarm system on this field in the form of a skirmish line. It was the first line of defense. If the Confederates advanced, the gunfire from the Union soldiers on the skirmish line would reveal the location of the attack, “Stonewall” Jackson was counting on it.
