The Roman Empire Order of Battle for the Civil Wars 68AD to 70AD is a Society of Ancients publication, written by Michael Lane. I lost my much-thumbed paper copy of this 86 A4-page booklet, around 6 months ago, and Dug Page-Croft recently and very generously bought me a replacement copy, on a disc, from the Society of Ancients.
This booklet is a fantastic source of information about the pay rates, organisation and the deployment of the Roman Legions, Praetorians and Auxiliaries from Augustus to Trajan. It is also a valuable source regarding the names of the legions and auxiliary cohorts (all mine are named from it), and can often provide information on where they were based, and when, and in the case of the legions, the commander's name when known. Finally it has orders of battles, diagrams and accounts of all the major battles in the 68-70AD Civil War, some illustrations and a timeline of events.
This is a must have for those interested in wargaming the period, I can’t recommend it highly enough! When my campaign eventually gets running, it’ll be based on this.
