This book discusses the Anglo-French military campaign in North China in 1860 and the destruction of Yuanmingyuan, the imperial palace compound north-west of Beijing. More generally the book deals with European imperalism in China (and elsewhere) in the 19th century and tries to make sense of the curious fact that civilized people often behaved in the most barbarian of ways.
The sources for the book will eventually all be available on these pages. You can also click and learn more about the North China Campaign of 1860, about the participants, the armies, and about Yuanmingyuan. Or read the book itself.
