Conqueror is the fourth and final book in the series depicting the life of Roman statesman and general Gnaeus Julius Agricola.
As with the earlier books - Invader, Warrior and Commander - the events in Conqueror are based on available historical sources, including Tacitus’s biography of Agricola (Tacitus was Agricola’s son-in-law) and the author’s own in-depth knowledge of the period. However, like the previous books, Conqueror is very much a picture of Agricola the man not just the historical figure.
Appointed its governor, Agricola returns to Britannia charged by the Emperor Vespasian with conquering the whole of the island and placing it under Roman control. It’s a huge task made even more challenging by being accompanied by a time limit, the withdrawal of legions to protect other parts of the Empire and, being Britannia, the weather. The pressure to complete the task, likely to be the defining moment of Agricola’s career, is always uppermost in his mind. It informs his tactics, the deployment of forces and increasingly requires a change of mindset. As the pressure to complete the task builds, we see a more ruthless side of Agricola, latterly influenced by tragic events in his personal life.
Agricola was ever the tactician but his relentless progress northwards, quelling the various tribes either through negotiation or direct engagement, really demonstrates his ability to innovate. For example, combining his land forces with the Roman fleet, which at the time was separately commanded. He never quite loses his desire to be at the heart of the action, fighting alongside his men, although now resigned to the fact that, as governor, he can only sit and watch. Well, for a time…
Some of the tribes Agricola encounters prove particularly hostile, seemingly preferring death over defeat. This leads to epic battle scenes including the climactic encounter with the Caledonii at Mons Graupius. It is a bloody affair leaving Agricola, even at the moment of conquest, feeling hollow at the loss of life. ‘All around him, a whole generation of humanity lay strewn in their own blood and gore.’
Being the final book in the series, it’s a time of partings, one especially poignant, and the end of longstanding relationships. As the author notes, history provides a bittersweet ending. As Tacitus records, ‘Perdomita Britannia et statim omissa‘ [Britain was conquered and immediately lost].
Conqueror brings to a close a series which combines fascinating historical detail with the immersive ‘cacophony of battle’.
