Marius' Mules

57 BC. The fearsome Belgae have gathered a great army to oppose Rome, and Fronto and the legions assemble once more to take Caesar's war against the most dangerous tribes in the northern world. While the legions battle the Celts in the fiercest war of Caesar's career, the plots and conspiracies against him, both at Rome and among his own army, become ever deeper and more dangerous.

It is 56 BC. As Fronto and his friends’ winter in Rome and Caesar in Illyricum, trouble is brewing in the north. The tribes of Armorica, driven to desperate action by the harsh rule of Crassus, raise their standards in defiance of the Roman eagle, causing a chain reaction that threatens everything the legions of Caesar have achieved. Meanwhile, in Rome, the conspiracies against Caesar take an unexpected turn, plunging Fronto and his friends into a world of crime, violence and intrigue that threaten everything the legate cares about.

55 BC and Caesar's army gathers in the north of Gaul, preparing to drive away invading Germanic peoples and to traverse the dangerous northern ocean bringing punishment to the tribes of Britannia for their assistance of Gaulish rebels. But Fronto's troubles don't stop there. As his burgeoning relationship with Lucilia steps to a new level, so do his responsibilities at home, a situation exacerbated by the disruptive influence of the villainous Clodius in the city, causing trouble and endangering those about whom Fronto cares most.

As tensions build in Gaul and the druids manoeuvre the tribes towards general rebellion, Priscus and the diminishing senior staff of Caesar's army prepare to return to Britannia, this time with a vast army and a will to crush the tribes of that mysterious island. Meanwhile, Fronto contemplates a non-military future as he settles into the life of a married nobleman, socialising with Rome's elite and coming to terms with the decline in his fitness.

It is the eve of destruction. Gaul seethes and bucks more than ever in revolt against the Roman invader, with even Caesar's allies beginning to question their loyalty. A conspiracy of Druids and Kings move the pieces into position in their great game of independence, all led by the powerful exile Vercingetorix. The lands of the Belgae burn in the vengeful aftermath of a winter that saw countless Romans butchered by the Eburone King: Ambiorix.

After many months of clandestine organisation, Vercingetorix, backed by the druids and leading an army of rebellious tribes, is ready to make his first moves towards independence for his people and the annihilation of Rome's presence in Gaul. Meanwhile, Caesar tends to business in Aquileia, unaware that he is cut off from the bulk of his army in the north by the rebellion. Fronto and his friends are heading for a clash of armies the likes of which the north has never seen, and the Tenth's legate is about to face his most trying year yet.

51 BC. In the aftermath of the dreadful siege of Alesia, the tribes of Gaul lie broken and sparse, and yet the fires of rebellion still burn in the hearts of a few. As Caesar and his army continue to pacify the land wherever revolt can be found, a new conspiracy is rising. Lucterius of the Cadurci, survivor of Alesia, seeks to raise a new great revolt, building an army in his homeland, while a small group of dangerous warriors embark upon a secret and dangerous mission to rebuild all that was lost in that great siege.

It is 50BC and Caesar winters with his legions in the north - all Gaul conquered but a triumphant return to Rome denied him by the senate who seek his blood. Yet unrest stirs in unknown lands, as the tribes of mountainous Aquitania rise under a terrifying new leader and drive out their Roman occupiers. Marcus Falerius Fronto, exiled from Rome, seeks out his former commander in an effort to build a future and soon finds himself in command of a most unusual legion with a remit to restore peace in Aquitania.

The war in Gaul is over, but the fight for Rome is only just beginning. Denied his consulship by the senate and nearing the end of his term as governor, Caesar waits at Ravenna with one legion, making a last attempt at reconciliation. Threatened with prosecution if he returns to Rome, just one path is becoming clear: war against the senate. Fronto and Galronus are bound to the service of the Proconsul, facing a war against other Romans, and able neither to prevent nor avoid it.

It is 48 BC, and Caesar is master of Rome, but Pompey is at large in the huge recruiting grounds of the east with a core of powerful officers, nominally representing the senate in absentia. As the general deals with matters in the city, his army gathers at the coast, waiting to cross the sea and fight that worst of all conflicts: civil war.

Winter, 48 BC. Caesar and his small force are trapped in the Egyptian city of Alexandria. Caught up in the dynastic struggles of the House of Ptolemy, the consul has sided with the clever and ruthless Queen Cleopatra. Her brother and fellow monarch, Ptolemy XIII, languishes in the palace, a hostage of Caesar's, while a huge army under the command of the Egyptian General Achillas closes on the city to free him.

46 BC. Pompey is dead, Egypt is settled and Rome is controlled by the loyal Marcus Antonius. As the new year looms, Rome's greatest general and dictator Julius Caesar moves precipitously to take on the last stronghold of the rebel faction: Africa. Crossing against all advice in the middle of winter, with minimal forces and little forward planning, the campaign almost dies before it begins, legions scattered across the sea by vicious storms, the general putting ashore with just a single legion and his most trusted veteran commander: Marcus Falerius Fronto.

The war in Africa is over and the rebel cause hangs by a thread. With opposition to Caesar now led by Labienus and by Pompey’s sons in Hispania, Caesar is one step from ending the civil war that has plagued Rome for years. Before the war can be pursued, though, Caesar has matters to attend to in Rome. And against a backdrop of glorious triumphs and civil friction, the general’s old warhorse Marcus Falerius Fronto begins to uncover a series of events that may have a cause in common.

The war in Gaul is over. The rebels are defeated. Now the battle for Rome has begun.
