The British Field Marshals 1736-1997: a Biographical Dictionary

 
From the publishers:
As General Sir Charles Guthrie (the first soldier to be denied promotion to Field Marshal on appointment to Chief of Defence Staff) observes in his foreword, Dr Tony Heathcote's reference work embraces the history of the British Army over the last 250-300 years. It covers not only the careers of key individuals but provides an understanding of their contribution to the successes and failures of our military past. […] Alongside the household names of the great strategists and distinguished leaders lie little known and forgotten figures, who gained their exalted rank by either luck, accident of birth or diplomatic gesture.
