From my battlefield visit this past Saturday, here’s a photo of Sudley Springs Ford on Catharpin Run, over which the divisions of Hunter and Heintzelman crossed on the morning of July 21, 1861. Compare it to the Barnard and Gibson photo from March 1862. Notice anything? See the pile of rubble on the other side of the run, left of center (click on the image if you can’t make it out)? They are all that remains of the Sudley Spring house. It appears nice and square in the 1862 photo to the left of the Union cavalrymen, who are facing off against the Thornberry kids on the near side. Look at the trees that frame the left of both photos. Clearly not the same trees, but notice how they are both leaning similarly. What does it mean? OK, nothing. But it’s cool, nonetheless.
