This book is a complete guide to the Regia Marina, the navy with which Italy fought the Second World War. Starting with the historical background, it describes how the navy developed, how it was organised, the facilities that supported it, and the operations it conducted both before and after the armistice in 1943. It also details all its ships, with full technical particulars, plans and photos. Furthermore, there are chapters on special topics like camouflage; uniforms, decorations and insignia; and a 'who's who' of important naval personalities; and the reference value of the book is enhanced by a comprehensive bibliography and guide to sources. The illustration is a noteworthy feature of the book as the author's collection of naval photographs is one of the best in Italy. He is also a fine draughtsman, and his ship plans and colour illustrations are both detailed and accurate, adding a particular appeal for modelmakers. Of all the main combatant navies of this era, the Italian is probably the most poorly represented in English publications, so this comprehensive handbook will be especially welcomed by the naval history community.
