I didn't know there was Bersaglieri in the Crimea. They were there under orders of Cavour - they acquired the red fez as an undress headgear in imitation of the Zouaves while there. Fought at the battle at Chernaya River.
This image is painted by British military man George Cadogan who captured quite a bit of the military life of the Crimea in beautiful watercolours. I haven't myself seen it but the book Cadogan's Crimea looks worth tracking down.
