At about the same time Birney's first attack moved forward, the Union XVIII Corps under Major General Edward Ord, assaulted Fort Harrison to the west of New Market Heights. Ord's assault was led by Brig. Gen. George Stannard, a veteran of Gettysburg. Stannard's men rushed across an open field and took cover in a slight depression just in front of the fort and, after a moment's rest, took the fort. The Confederate defenders broke to the rear, seeking refuge behind a secondary line. Brig. Gen. Hiram Burnham was killed during the attack, and the Union troops renamed the captured fort in his honor.
