On both July 2nd and 3rd, Lieutenant Colonel Freeman McGilvery’s line of artillery on Cemetery Ridge played a crucial role in repelling massive attacks by the Army of Northern Virginia. Although McGilvery’s performance at Gettysburg usually receives honorable mention, in most cases that praise amounts to a passing glance. This tour will explore not only the man, but also analyze his performance at Gettysburg in some detail. Along the way, we will meet the men that fought under him and play witness to the actions in which they participated on the second and third days of the battle. We will meet at the Third Corps Headquarters marker across from the Trostle barn and finish on Hancock Avenue near the New York Auxiliary Monument (bring your walking shoes!).
