Based on archive research, this is a detailed study of the history and personnel of a single unit of Napoleon's Imperial Guard, 1810-1815 - the 2nd Light Horse or Red Lancers. Their part in the Napoleonic Wars is covered, from the 1812 Russian Campaign, through the defensive campaigns in Germany and France in 1813-14, to the fateful 100 days of 1815 and to the final sunset at Waterloo. This work is illustrated with many period paintings, some previously unpublished, and detailed appendices on known members of the regiment.
