The concept of the bodyguard is as ancient as the practice of an individual assuming the leadership of a group or tribe. From the Companions of Alexander to the Varangians of Byzantium, bodies of .lite warriors, owing personal allegiance to their sovereign and obeying no others, have illuminated or stained the annals of military history. Napoleon's Imperial Guards probably represent the last true link in a chain spanning the ages. Philip Haythornthwaite describes the history, organisation and equipment of Napoleon's Guard Infantry in an engaging work which includes numerous illustrations and eight full page colour plates superbly drawn by Bryan Fosten.
