Subtitled 'Actions and losses in personnel, colours, standards and artillery, 1792 - 1815', the Greenhill Napoleonic Wars Data Book is a monumental achievement. Smith has trawled through almost every exchange of gunfire during the French Revolutionary and Napoleonic Wars to compile the ultimate in reference books listing in chronological order, not just the name, date and location of a battle, but the forces involved - including the commanders, their ranks and the names and types of units - the losses taken and the sources, as well as the occasional comment. In some cases Smith can even tell you the number of men taken prisoner and which unit seized them. The result is a five star book produced by real academic legwork.
