Hey, r/AskHistorians! This is my first post, so forgive me if I'm doing it wrong. Anyway, down to business. I was surfing the vast seas of the internet the other day and I came across a photo on a blog that fascinated me. The blogger claims that it is an actual combat photo from the Franco-Prussian War. Now, I know that war photography kind of came into its own during the Crimean War just a few years earlier and that it had also seen widespread use during the American Civil War, but this photo looks too good to be true for the time period...in addition, I've never seen it before in my life. Anyway, I was wondering if there is anyone here who could shed some light on this fascinating photograph for me. Thanks!

TL;DR: Found old photograph online, supposedly from the Franco-Prussian War, wondering if it is what it claims to be
