Richard H. Anderson
In April 1863, Harrow was finally promoted to brigadier general and led the 1st Brigade, 2nd Division, II Corps, during the Gettysburg Campaign. On July 2 at the Battle of Gettysburg elements of his brigade were engaged against the attack of Maj. Gen. Richard H. Anderson on the Union lines. Most notably the 1st Minnesota Volunteer Infantry distinguished itself in stalling a Confederate attack on an under-defended part of the Federal line. Harrow served as acting division commander while Brig. Gen. John Gibbon led the corps late in the day. Maj. Gen. Winfield S. Hancock at that time was in charge of the left flank of the army.
