Philip Haythornthwaite is one of the most distinguished and prolific writers on the military history of the Napoleonic era. He has long been established as an authority on the major battles of the time, in particular those fought in the Iberian peninsula, and he has made a special study of the armies and the soldiers who confronted each other across Europe during 15 years of almost continuous warfare. His many previous books include: The Peninsular War: The Complete Companion to the Iberian Campaigns 1807-14; The Armies of Wellington; Waterloo Men: The Experience of Battle, 16-18 June 1815; Die Hard! Famous Napoleonic Battles; The Napoleonic Source Book; Who Was Who in the Napoleonic Wars; Wellington's Army: The Uniforms of the British Soldier 1812-1815 and Waterloo Armies.

In the two hundred years since the Battle of Waterloo countless studies examining almost every aspect of this momentous event have been published narratives of the campaign, graphic accounts of key stages in the fighting or of the role played by a regiment or by an individual who was there - an eyewitness. But what has not been written is an in-depth study of a division, one of the larger formations that made up the armies on that decisive battlefield, and that is exactly the purpose of Philip Haythornthwaites original and highly readable new book. He concentrates on the famous Fifth Division, commanded by Sir Thomas Picton, which was a key element in Wellingtons Reserve. The experiences of this division form a microcosm of those of the entire army. Vividly, using a range of first-hand accounts, the author describes the actions of the officers and men throughout this short, intense campaign, in particular their involvement the fighting at Quatre Bras and at Waterloo itself.
