It wasn't until John Keegan's book The Face of Battle was published in 1976 that historians started to look at battle from the perspective of the ordinary soldier. ‘Fighting’ looks at ancient land battles, siege warfare, and naval warfare sketching the development of techniques and exploring a specific dimension of the psychology of combat. What can we learn about leadership in classical world from this sort of study? What was the role of the Greek hoplite? How did a Macedonian phalanx differ from a hoplite phalanx? John Keegan's book has encouraged classical historians to apply the conclusions of studies of psychology in modern combat to the ancient world.
