Additionally, I met a ranger whose ancestor fought with the 48th PVI and who is passionate about the history of the 48th. That was a really interesting experience meeting another descendant of the 48th.
Unfortunately, the part of the battlefield occupied by the 48th during the battle of Cold Harbor is not part of the public battlefield trust and is privately held. It is located some 4 miles north of the park, so I was unable to visit the exact location where John W. Derr was encamped and fought. However, I was able to get the feel of the battlefield while walking in the woods and around the trenches that remain and were dug by both Confederate and Union forces.
Overall a great experience and I thank both the Park Service and the reenactors for a great day at Cold Harbor. The best part was taking my grandson to see the park....John W. Derr's great-great-great-great grandson....
