The Gettysburg Discussion Group (GDG) has some great articles on the opening day of the Battle of Gettysburg. I’m particularly fond of the discussion on the area known as Oak Ridge because the 11th PVI and Sallie their mascot fought there before retreating through town to the safety of Cemetery Hill.
