This final volume in the Roman Conquests series examines some of the best-known Roman campaigns. Julius Caesar's involvement and the commentaries he wrote on these campaigns make them among the most studied daily strategies of antiquity. Before Caesar, Rome had already established its position in the Alps in Gaul (in modern Provence), and Michael M. Sage begins with these early acquisitions, which were largely reactive and defensive. The Gauls, one of the greatest warring societies of ancient Europe, suffered some of Rome's heaviest defeats at the end of the second century BC. This context makes Caesar's bold campaigns even more remarkable, with which he quickly completed the initial conquest of the remaining part of Gaul. The subsequent uprisings that followed, culminating in the great unified revolt under Vercingetorix, are also covered in detail, with the epic siege of Alesia being the dramatic climax. Michael Sage narrates and analyzes all these campaigns, showing how the Roman war machine eventually managed to overcome the vastly superior numbers of Celtic warriors to expand Rome's dominion from the Mediterranean to the English Channel.
