This collection of photos is so awesome. 1855 isn’t a time that I readily associate with lots of photography (the technology was still so new!) and the Crimean War definitely isn’t one I’d associate with war photography!
Here’s another photo from the Roger Fenton collection, this one showing a British light artillery division. The caption reads:
“Mortar batteries in front of Picquet house Light Division. Photo shows five men and three mortars at a mortar battery with bomb-proof shelter.”
