the interesting things is the presence of Neapolitan prisoners..some of them in red pants...mixed with crey-blue ones...service and campaign uniforms items together...
the evidence of their use in battle is given in a book from a Garibaldini in which answering to the alarmed question from a Sicilian gentleman volunteer (traitor) : "beware French units are present on the battlefield"..he answered.."take it easy..also the Neapolitans wear red trousers"
