At the Second Battle of Bull Run (also known as the Second Battle of Manassas), the 5th New York Volunteer Infantry regiment was forced to withstand the advancing forces of General James Longstreet. In underestimating the size of the Confederate army, Pope ordered the regiment to support Hazlett’s Battery.
