There are two monuments to O’Neal’s Brigade, one northwest of Gettysburg on Oak Hill (North Confederate Avenue tour map) and the second southeast of town on East Confederate Avenue (East Confederate Avenue tour map).
The brigade was commanded at the Battle of Gettysburg by Colonel Edward A. O’Neal of the 9th Alabama Infantry, an Alabama judge and lawyer. O’Neal had been commanding the brigade since March, when its commander, Robert Rodes, had been promoted to division command. O’Neal had been appointed brigadier general after the Battle of Chancellorsville, but Robert E. Lee had held up his apointment, which was then cancelled by President Davis.
From the Oak Hill marker:
July 1. Soon after arriving at this position three regiments attacked the Union flank, the 5th Regiment being ordered to guard the wide interval between the Brigade and Doles’s Brigade in the valley on the left and the 3rd Regiment joining Daniel’s and afterwards Ramseur’s Brigade. The three regiments were repulsed with heavy loss but the entire Brigade took part in the general attack soon made by the Confederates which finally dislodged the Union forces from Seminary Ridge.
July 2. The Brigade in position all day in or near the town but not engaged.
July 3. The 5th Regiment lay in the southern borders of the town firing upon the Union artillery with their long range rifles. The other regiments moved to Culp’s Hill to reinforce Johnson’s Division.
