Paolo,
Look Charles Napier's account of the battle of Coruna (16 January 1809):
William Napier Bruce, Life of General Sir Charles Napier, G.C.B, London, 1885, p. 29–30.

Charles Napier was the commander of the 50th Regiment. He mentions an Italian among the French soldiers who took him prisoner. Although I think that you will not like what he wrote about the Italian.

Best wishes,
Alexander
