Here are a few pictures of the Brompton oak tree. The last couple of pictures were taken of the wounded around the same oak tree in 1864. That was 164 years ago. And in the pictures from 1864 the tree doesn't exactly look small. My guess is that is somewhere around 200 years old.
When the battles of the Wilderness and Chancellorsville were fought the grounds of the house were used as a hospital. The wounded were brought here and treated and then waited to be transported to Washington.
