This is the fourth in a five book series, The Rutilius Journals, which sets out to tell the fictional story of one extraordinary Roman during the Gallic Wars that Julius Caesar fought between the years 58 and 50 BC and about which he wrote his famous eight-book Commentaries, "De Bello Gallico," the bane of many a Latin student's life in the run up to GCE exams in the days when Latin was a university entrance requirement for degree studies even in the scientific disciplines. The first person hero of the story is Marcus Rutilius alias Mike Oakwood, a British Army officer on secondment to a European Border Police Force serving in the Balkans. He is knocked out on a 21st Century battlefield fighting in an escalating war against illegal immigration into the EU and comes to when the fighting is over on the same battlefield... in the year 60 BC, still a captain - or rather a military tribune - in the famous Tenth Legion of the Roman Army. The first two books, Caesar's Tribune and Master of Gaul, took Mike, from his traumatic transformation into Marcus, through Caesar's consulship in 59 BC and on through his dramatic involvement in both the actual fighting and the political wrangling against which Caesar and his colleagues, Pompey and Crassus had to struggle. Book Three, Albion Ablaze, took Marcus back to his roots in proto-Kent, closing at the end of 54 BC with Caesar's withdrawal from Britannia after his decisive defeat of Cassivellaunus, the dictatorial paramount chieftain of Eastern Britain. Now Marcus faces a new task - to get Pompey back on-side after the death of his young wife, Julia, Caesar's beloved daughter. Reluctantly, Marcus accepts an assignment given him by Pompey to act as his liaison officer with Marcus Crassus, Caesar's early financial backer in his rise to power, and later an active partner in the political Triumvirate with Caesar and Pompey. This takes Marcus out of his usual sphere of operations in Gaul to the other side of the Mediterranean, following Crassus's fortunes in his bid to drive the Parthians out of Mesopotamia modern Iraq) and foil their advance into territory in Asia Minor that the Romans considered to be part of their burgeoning new empire. Returning to Caesar's armies at the end of that tragic episode, Marcus is welcomed back onto Caesar's staff with fresh assignments that take him and his now familiar circle of friends and family first back to England, then through the worst year of fighting in Gaul, as Caesar puts down the great rebellion led by Vercingetorix, the warrior chieftain of all Gaul, with its climax at Alesia at the end of the campaign season of 52 BC.
