Intelligence was just as important in the Napoleonic Wars as it is today. Then there was only one way of obtaining it – by spies and informers. The Author uses first hand accounts of three of Wellington's most daring and successful Intelligence Officers. The three men, all of Scottish descent, were very different in character. One was killed in action and another taken prisoner and after narrowly avoiding summary execution made a dramatic escape. There is a romantic angle too. Their stories skilfully interwoven against the backdrop of the brutal Peninsula War where atrocities were common place. This book gives a fresh insight into Wellington's remarkable triumph over Napoleon's armies.
