From Eric Mink:
No single site in the Fredericksburg area received more attention from Civil War photographers than “Brompton,” the John L. Marye plantation. Between May 19 and 20, 1864, no fewer than three photographers took nearly a dozen photographs at Brompton. What attracted the photographers were the scenes in the yard, where Union casualties lay waiting for medical attention. Brompton served at that time as a military hospital caring for the wounded and sick of the Union’s 9th Army Corps.
Personally, of all the photographs from this Brompton series, the image that has always intrigued me is one that depicts a small group of wounded soldiers lying beneath a small tree. A member of photographer Matthew Brady’s firm took the photo and it bears the original caption of “Wounded Indians.”
