Roman Battle Tactics by Nic Fields, Ph.D. is an excellently researched instructive manual on the various skirmishes and war maneuvers of the Roman Empire from 390 B.C. to 110 B.C. Fields displays his extensive knowledge of ancient history brilliantly, and without sounding the least bit dry... The chronological explanations of the names, uses, weapons, and training methods of each type of unit the Romans used was especially helpful in understanding how each victory came about.
