Battle of Alesia (52 BC)

In the summer of 52 BC Caesar besieged Alesia, where Vercingetorix had taken refuge with his warriors. When a relief force came from all over Gaul, he built a second wall and fought on two fronts. Plutarch gives figures: one hundred seventy thousand in the town and three hundred thousand in the relief army. They are probably inflated.
After the victory Vercingetorix surrendered to Caesar.
