I would love to see some actual combat photography from the Civil War. Of course, the nature of photography in the 1860s was such that long exposures would render action shots nothing but big blurs. So nearly all images from the war are posed. From time to time, you might run across a "posed" action shot - like pretend sword fighting or something along those lines. And then there are the unusual shots of soldiers on the march - like this one of Confederates marching through Frederick, Maryland. It is a great image of soldiers on campaign - what they would carry and how they generally looked while on the move.
