To gain the upper hand in conflict the ability to know what your enemy is planning is vital. Massive amounts of money have been spent and many lives have been lost in pursuit of this objective. From biblical times to the present day, leaders have employed espionage on and off the battlefield in the quest for victory. Tactics might differ, from dirty tricks and theft to interrogation and torture, but the aim is the same - to outmanoeuvre your enemy and emerge triumphant. Separating myth from reality, the Enemy Within, traces the history of espionage from its development in ancient times through to the end of the Cold War and beyond, shedding light on the clandestine activities that have so often tipped the balance in times of war. This detailed account delves into the murky depths of the realm of the spymasters and their spies, revealing many amazing, and often bizarre stories, along the way. From the Monkey hanged as a spy during the Napoleonic wars to the British Double Cross Committee in World War II and from Ivan the Terrible's forming of the first Russian secret police in the 16th century to the infiltration of the IRA in the 20th century, this journey through the history of espionage shows us that be they thrill seekers or madmen, fanatics or tricksters no two spies are alike and their fascinating stories are fraught with danger and intrigue.CHAPTER HEADS In ancient times.

Through this association he developed a passionate interest in the Napoleonic Wars and participated in many of the bicentennial celebrations marking the wars of the French Revolution. His enthusiasm led to significant research in the French military archives at the Château de Vincennes near Paris. Terry became equally passionate about the history of 'Secret War' - in particular military espionage - a subject he feels is too often overlooked. After a long stint as bass guitarist for the rock group "Soma", Terry put pen to paper and is now the author of a number of books and articles on military history. He lives in Kent, England. The author lives in Kent, UK.
