Just read a few minutes ago that a portion (small portion) of the Ox Hill or Chantilly, Virginia, battlefield will become a battlefield park. Apparently, the park will contain less than 5 acres – all that it left of the battlefield. Everything else has been paved over or built upon. There were two brigades of North Carolinians at this battle, fought just outside of Washington, D.C., on September 1, 1862: Branch’s brigade (7th, 18th, 28th, 33rd, and 37th NCTs) and Pender’s brigade (16th, 22nd, 34th, and 38th NCTs), along with the 21st NCT of Trimble’s brigade, and Latham’s Battery. The preserved spot is near where these brigades fought, but I believe that both of these position are now topped by houses.
As many of you know, I wrote a history of the 37th NCT. This is the only battlefield (of 30+) where they fougt that I have not visited.
