Barbero has mastered the vast scholarly output on his subject. He possesses the historian's gift of summarizing a complex situation in a single sentence.Raymond Carr
On the lines of Peter Heather's brilliant The Fall of the Roman Empire... A cracking tale, well researched and beautifully paced.Peter Jones
[Barbero's] lucid, flowing narrative not only brings alive the military leaders and the problems they had to overcome, but also re-creates the lot of the ordinary footsoldiers. Rarely is history recounted in such a stimulating fashion.
