"In The Nisibis War Harris offers us some excellent strategic analysis, helping explain the many military problems confronting the late empire, and evaluating the abilities of the respective armies and leaders, particularly the over-rated Julian, altogether providing us with a good account of a very confusing conflict, in an area still in contention."-- "StrategyPage" "This is a good account of a very confusing conflict, in an area still in contention."-- "The NYMAS Review, Autumn 2017"
