P.H. Tilson died on July 21, 1861 at the Battle of Bull Run. The goal of the battle was to force the Confederates to retreat to their next line of defense; the Rappahannock River. The Union Army consisted of 28,000 men and was to assault the Confederates' 33,000-man army with three separate flanks. Before the battle began, General McDowell called 5,000 men to guard the rear of the army. After Union guns were captured, the Union Army was forced to retreat with the majority of its army still intact. P.H. Tilson’s cause of death was a cannon ball that severed his legs from his body.
