William Simpson (1823-1899) was a Scottish artist. One of his main activities was to act as a "war correspondent" during the Crimean War. Visiting the battlefields of the war, he painted watercolors, which he sent back to London to be turned into lithographs for publication. He was paid 20 pounds (a tidy sum) for each picture.
After the Crimea, he was active in India, Abyssinia, France, and Afghanistan. The guy got around. The pictures here are all from the Crimea.
