Vercingetorix now threw himself into Alesia, a strong place in the hills, probably to be identified with Alise-Sainte-Reine in Burgundy. He sent messengers to the various States in alliance, asking for a _levée-en-masse_. This was not made, but a huge army was gathered, 250,000 infantry and 8,000 horse. It was the last great effort of Gaul for freedom, and it failed. The Gauls came on, convinced that they must triumph, but the Romans stood firm during a struggle that lasted from noon till sunset, and the enemy were driven back to their camp. Another attack, made after a brief rest, failed also. Then came the last desperate struggle. One of the chiefs of the relieving army, a kinsman of Vercingetorix, threw himself on a weak spot in the lines of investment, where the Roman camp had been constructed on ground that sloped towards the town. He had 60,000 men with him; the Roman force consisted of two legions. The besieged made a simultaneous effort to break out. The struggle was long and fierce. Cæsar directed the Roman battle from a point of advantage. When the time came, he himself, conspicuous in the scarlet cloak of command, took personal part in the struggle. His trusted lieutenant Labienus got together forty cohorts from all parts of the lines of investment, and Cæsar put himself at their head. The Gallic host was utterly broken. The slaughter on the field was great, and the survivors dispersed during the night that followed, every man seeking his native State. The next day Vercingetorix surrendered himself to the conqueror. He was kept in prison for seven years, was led in the triumph which Cæsar celebrated in 45 B.C. and put to death afterwards. The war in Gaul lasted for two years more. One after another the rebellious States were subdued, and dealt with mercifully or severely as policy dictated. Cæsar, who recognised the duty, or, anyhow, the policy, of forgiveness where his countrymen were concerned, was wholly proof against any emotion of the kind when he had to do with barbarians. He had no pleasure in a massacre; but, on the other hand, it caused him no compunction or even pain. These eight years of war must have cost Gaul some two millions of lives. It was an awful price to pay, but it completed a great work, which had been on hand for three centuries and a half. In 390 B.C. Brennus captured Rome; in 50 B.C. the Gauls had become the Latin people which they are to-day. VII FURTHEST BRITAIN. I cannot omit all mention of our own island, though it can hardly be said that there was any incident in its history of really critical importance in the long struggle between Rome and the barbarian tribes.
