The Thirteenth New Hampshire had its first taste of military action early this morning, as the regiment arose before dawn and left camp at 7:00 A.M. with knapsacks, haversacks, and arms for Upton Hill, about two miles from Falls Church and fifteen miles from the Bull Run battlefield. Arriving at 11:30 A.M. two companies of the Thirteenth immediately deployed for picket duty beyond the earthwork defenses of Washington, while the remaining companies camped, mainly without tents, on open ground.1
