Union Headquarters monuments


The monument to the Army of the Potomac’s Engineer Brigade is south of Gettysburg on Pleasonton Avenue. (Pleasonton Avenue tour map)

The brigade was commanded during the Gettysburg Campaign by Brigadier General Henry Benham (West Point Class of 1837), a career engineer officer from Connecticut. Like a number of units honored along Pleasonton Avenue, the engineers were not at Gettysburg but played an important part in the campaign.
