John Adams, who met his advance column and drove it back at Mechanicsburg, reported still more destruction.
Early in June the Federal works had been pushed up very close, especially in front of Lee and Forney, and the Federal mines crept still closer, particularly toward the Graveyard redan, the Third Louisiana redan on the Jackson road, and the lunette on the Baldwin’s Ferry road. The Confederates threw up new lines of defense behind these points and countermined. On the 19th of June the Federal works on the Graveyard road were within twenty feet of our redan.
