Major General George Sykes
The Fifth Corps was commanded at the Battle of Gettysburg by Major General George Sykes (West Point Class of 1842), a career Army officer from Delaware. Sykes had commanded the solid core of United States Regular Infantry that had been with the army since the first Battle of Bull Run. At Gettysburg the Regulars made up the Second Division of the Fifth Corps, which had been Sykes’ command before Meade’s promotion to commander of the Army of the Potomac on June 28 suddenly threw Sykes into command of the Fifth Corps.
