The Alpine March of 1985 and its documentation were groundbreaking for experimental archaeology and the study of ancient military history. The long out-of-print classic of Roman reenactment is now available in a significantly expanded and updated form. At the same time, the work provides a comprehensive depiction of the Roman military during its most important period, the transition from the Republic to the Imperial era. There is still no other book that addresses the practical aspects of ancient military life with such uncompromising precision and comparable vividness.
