Union Headquarters monuments

The monument to the Army of the Potomac’s Engineer Brigade is south of Gettysburg on Pleasonton Avenue. (39.808019° W, 77.232962° W; Google map; Tour map: Pleasonton Avenue)

The brigade was commanded during the Gettysburg Campaign by Brigadier General Henry Benham (USMA ’37), 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.
