This book deals with the decade of life of the Kingdom of Italy. Its armed forces are analyzed, described and illustrated here: from infantry to cavalry, from artillery to all the other armed corps of the state; the soldiers of the Royal Guard, of the line, of the volunteer corps and others. Studied is the military costume of the Italian soldier dressed in imitation of the French one, but with some curious variations. The appendix to each volume also narrates the main events of arms that involved this Napoleonic army. From the wars in Spain to the Russian campaign and the clashes on the eastern front of the Kingdom, the so-called Friuli campaigns.
