Cæsar had repaired from the left wing to the other points of the line. When he arrived at the right wing, he had found the 7th and 12th legions hotly engaged, the ensigns of the cohorts of the 12th legion collected on the same point, the soldiers pressed together and mutually embarrassing each other, all the centurions of the 4th cohort and the standard-bearer killed; the standard lost; in the other cohorts most of the centurions were either killed or wounded, and among the latter was the primipilus Sextius Baculus, a man of rare bravery, who was destined soon afterwards to save the legion of Galba in the Valais. The soldiers who still resisted were exhausted, and those of the last ranks were quitting the ranks to avoid the missiles; new troops of enemies continually climbed the hill, some advancing to the front against the Romans, the others turning them on the two wings. In this extreme danger, Cæsar judges that he can hope for succour only from himself: having arrived without buckler, he seizes that of a legionary of the last ranks and rushes to the first line; there, calling the centurions by their names and exciting the soldiers, he draws the 12th legion forward, and causes more interval to be made between the files of the companies in order to facilitate the handling of their swords. His example and encouraging words restore hope to the combatants and revive their courage. Each man, under the eyes of their general, shows new energy, and this heroic devotedness begins to cool the impetuosity of the enemy. Not far thence, the 7th legion was pressed by a multitude of assailants. Cæsar orders the tribunes gradually to bring the two legions back to back, so that each presented its front to the enemy in opposite directions. Fearing no longer to be taken in the rear, they resist with firmness, and fight with new ardour. While Cæsar is thus occupied, the two legions of the rear-guard, which formed the escort of the baggage (the 13th and 14th), informed of what was taking place, arrive in haste, and appear in view of the enemy at the top of the hill. On his part, T. Labienus, who, at the head of the 9th and 10th legions, had made himself master of the enemy’s camp on the heights of Haumont, discovers what is passing in the Roman camp. He judges, by the flight of the cavalry and servants, the greatness of the danger with which Cæsar is threatened, and sends the 10th legion to his succour, which, re-passing the Sambre, and climbing the slopes of Neuf-Mesnil, runs in haste to fall upon the rear of the Nervii.
