"Gentlemen's Sons" is a well-written account of the experiences of the British Army's elite Guards battalions in the Peninsular War and at the Battle of Waterloo between 1808 and 1815. Infantry battalions from the Guards managed to be present and to serve with distinction at virtually every major battle fought by the Duke of Wellington's Anglo-Portuguese army in the Iberian Peninsula and France, and in the key battles of the Waterloo campaign. The authors bring a deep familiarity with the Napoleonic era to bear in tightly-written descriptions of the individual battles. The narrative provides a fairly standard interpretation of events, but even serious students of the era should particularly enjoy the chapter on the heroic defense of the farmhouse of Hougoumont at Waterloo. The book is lavishly illustrated with portraits, sketches, and diagrams. The narrow focus on the exploits of the Guards does presuppose some knowledge of the context of the Napoleonic wars; readers seeking a broader perspective should consult one of many general histories available of the Napoleonic wars. At the same time, the book will be accessible to those readers with at least a casual interest in military affairs.
