Victor Davis Hanson explains in great detail just how the ancient Greek cities went about the task of killing each other's citizens. It makes a remarkable story. For several hundred years they went after each other in a very particular way. I am a life long history fan and have had an interest in things military for over 50 years. I learned a great deal and a lot of odd and disconnected facts in my noggin got put into perspective. Hanson writes in a way that the ordinary, non specialist reader can easily grasp and assimilate. Highly recommended.
