George --

I'm in agreement, but will try to answer an follow-up question you may have about marked Confederate burials in the area. Most of those date from the spring of 1863. I don't recall any dating from 1862.

There must have been hundreds of Confederate burials there in 1862, but markers for them didn't survive.

You could order the service file from the link you've seen at the top of this page and determine the location of the hospital, if one is recorded. Any cemetery used by the hospital would have been nearby. Whether anything from that period exists today is another matter.
