Peter Doyle is a geologist with a life-long interest in military history. Author of several books on his professional subject - palaeontology - he also writes on the role that terrain has had to play in two centuries of warfare. His interests extend beyond the scientific, though; he has written extensively on the British experience of warfare in the two world wars - illustrated with artefacts of those wars. He believes that objects have a tale to tell; he has tried to translate that for the general public.
