Caesar, on his own responsibility, raised two more legions and sent them across the Alps in the spring. When the grass began to grow he followed himself. Suddenly, before any one looked for him, he was on the Marne with his army. The Remi (people of Rheims), startled by his unexpected appearance, sent envoys with their submission and offers of hostages. The other Belgian tribes, they said, were determined upon war, and were calling all their warriors under arms. Their united forces were reported to amount to 300,000. The Bellovaci from the mouth of the Seine had sent 60,000; the Suessiones from Soissons 50,000; the Nervii, between the Sambre and the Scheldt, 50,000; Arras and Amiens, 25,000; the coast tribes, 36,000; and the tribes between the Ardennes and the Rhine, called collectively Germani, 40,000 more. This irregular host was gathered in the forests between Laon and Soissons.

Caesar did not wait for them to move. He advanced at once to Rheims, where he called the Senate together and encouraged them to be constant to the Roman alliance. He sent a party of Aedui down the Seine to harass the territory of the Bellovaci and recall them to their own defence; and he went on himself to the Aisne, which he crossed by a bridge already existing at Berry-au-Bac. There, with the bridge and river at his back, he formed an entrenched camp of extraordinary strength, with a wall 12 feet high and a fosse 22 feet deep. Against an attack with modern artillery such defences would, of course, be idle. As the art of war then stood, they were impregnable. In this position Caesar waited, leaving six cohorts on the left bank to guard the other end of the bridge. The Belgae came forward and encamped in his front. Their watch-fires at night were seen stretching along a line eight miles wide. Caesar, after feeling his way with his cavalry, found a rounded ridge projecting like a promontory into the plain where the Belgian host was lying. On this he advanced his legions, protecting his flanks with continuous trenches and earthworks, on which were placed heavy cross-bows, the ancient predecessors of cannon. Between these lines, if he attacked the enemy and failed, he had a secure retreat. A marsh lay between the armies; and each waited for the other to cross. The Belgians, impatient of delay, flung themselves suddenly on one side and began to pour across the river, intending to destroy the cohorts on the other bank, to cut the bridge, and burn and plunder among the Remi. Caesar calmly sent back his cavalry and his archers and slingers. They caught the enemy in the water or struggling out of it in confusion; all who had got over were killed; multitudes were slaughtered in the river; others, trying to cross on the bodies of their comrades, were driven back. The confederates, shattered at a single defeat, broke up like an exploded shell. Their provisions had run short. They melted away and dispersed to their homes, Labienus pursuing and cutting down all that he could overtake.

The Roman loss was insignificant in this battle. The most remarkable feature in Caesar’s campaigns, and that which indicates most clearly his greatness as a commander, was the smallness of the number of men that he ever lost, either by the sword or by wear and tear. No general was ever so careful of his soldiers’ lives.

Soissons, a fortified Belgian town, surrendered the next day. From Soissons Caesar marched on Breteuil and thence on Amiens, which surrendered also. The Bellovaci sent in their submission, the leaders of the war party having fled to Britain. Caesar treated them all with scrupulous forbearance, demanding nothing but hostages for their future good behavior. His intention at this time was apparently not to annex any of these tribes to Rome, but to settle the country in a quasi-independence under an Aeduan hegemony.

But the strongest member of the confederacy was still unsubdued. The hardy, brave, and water-drinking Nervii remained defiant. The Nervii would send no envoys; they would listen to no terms of peace. [5] Caesar learnt that they were expecting to be joined by the Aduatuci, a tribe of pure Germans, who had been left behind near Liége at the time of the invasion of the Teutons. Preferring to engage them separately, he marched from Amiens through Cambray, and sent forward some officers and pioneers to choose a spot for a camp on the Sambre. Certain Gauls, who had observed his habits on march, deserted to the Nervii, and informed them that usually a single legion went in advance, the baggage-wagons followed, and the rest of the army came in the rear. By a sudden attack in front they could overwhelm the advanced troops, plunder the carts, and escape before they could be overtaken. It happened that on this occasion the order was reversed. The country was enclosed with thick fences, which required to be cut through. Six legions marched in front, clearing a road; the carts came next, and two legions behind. The site selected by the officers was on the left bank of the Sambre at Maubeuge, fifty miles above Namur. The ground sloped easily down to the river, which was there about a yard in depth. There was a corresponding rise on the other side, which was densely covered with wood. In this wood the whole force of the Nervii lay concealed, a few only showing themselves on the water side. Caesar’s light horse which had gone forward, seeing a mere handful of stragglers, rode through the stream and skirmished with them; but the enemy retired under cover; the horse did not pursue; the six legions came up, and, not dreaming of the nearness of the enemy, laid aside their arms and went to work intrenching with spade and mattock. The baggage-wagons began presently to appear at the crest of the hill, the signal for which the Nervii had waited; and in a moment all along the river sixty thousand of them rushed out of the forest, sent the cavalry flying, and came on so impetuously that, as Caesar said, they seemed to be in the wood, in the water, and up the opposite bank at sword’s point with the legions at the same moment. The surprise was complete: the Roman army was in confusion. Many of the soldiers were scattered at a distance, cutting turf. None were in their ranks, and none were armed. Never in all his campaigns was Caesar in greater danger. He could himself give no general orders which there was time to observe. Two points only, he said, were in his favor. The men themselves were intelligent and experienced, and knew what they had to do; and the officers were all present, because he had directed that none of them should leave their companies till the camp was completed. The troops were spread loosely in their legions along the brow of the ridge. Caesar joined the 10th on his right wing, and had but time to tell the men to be cool and not to agitate themselves, when the enemy were upon them. So sudden was the onslaught that they could neither put their helmets on, nor strip the coverings from their shields, nor find their places in the ranks. They fought where they stood among thick hedges which obstructed the sight of what was passing elsewhere. Though the Aduatuci had not come up, the Nervii had allies with them from Arras and the Somme. The allies encountered the 8th, 9th, 10th, and 11th legions, and were driven rapidly back down the hill through the river. The Romans, led by Labienus, crossed in pursuit, followed them into the forest, and took their camp. The Nervii meanwhile flung themselves with all their force on the two legions on the left, the 12th and 7th, enveloped them with their numbers, penetrated behind them, and fell upon the baggage-wagons. The light troops and the camp-followers fled in all directions. The legionaries, crowded together in confusion, were fighting at disadvantage, and were falling thick and fast. A party of horse from Trèves, who had come to treat with Caesar, thought that all was lost, and rode off to tell their countrymen that the Romans were destroyed.

Caesar, who was in the other wing, learning late what was going on, hurried to the scene. He found the standards huddled together, the men packed so close that they could not use their swords, almost all the officers killed or wounded, and one of the best of them, Sextius Baculus (Caesar always paused in his narrative to note any one who specially distinguished himself), scarce able to stand. Caesar had come up unarmed. He snatched a shield from a soldier, and, bareheaded, flew to the front. He was known; he addressed the centurions by their names. He bade them open their ranks and give the men room to strike. His presence and his calmness gave them back their confidence. In the worst extremities he observes that soldiers will fight well under their commander’s eye. The cohorts formed into order. The enemy was checked. The two legions from the rear, who had learnt the danger from the flying camp-followers, came up. Labienus, from the opposite hill, saw what had happened, and sent the 10th legion back. All was now changed. The fugitives, ashamed of their cowardice, rallied, and were eager to atone for it. The Nervii fought with a courage which filled Caesar with admiration—men of greater spirit he said that he had never seen. As their first ranks fell, they piled the bodies of their comrades into heaps, and from the top of them hurled back the Roman javelins. They would not fly; they dropped where they stood; and the battle ended only with their extermination. Out of 600 senators there survived but three; out of 60,000 men able to bear arms, only 500. The aged of the tribe, and the women and children, who had been left in the morasses for security, sent in their surrender, their warriors being all dead. They professed to fear lest they might be destroyed by neighboring clans who were on bad terms with them. Caesar received them and protected them, and gave severe injunctions that they should suffer no injury.

By the victory over the Nervii the Belgian confederacy was almost extinguished. The German Aduatuci remained only to be brought to submission. They had been on their way to join their countrymen; they were too late for the battle, and returned and shut themselves up in Namur, the strongest position in the Low Countries. Caesar, after a short rest, pushed on and came under their walls. The Aduatuci were a race of giants, and were at first defiant. When they saw the Romans’ siege-towers in preparation, they could not believe that men so small could move such vast machines. When the towers began to approach, they lost heart and sued for terms. Caesar promised to spare their lives and properties if they surrendered immediately, but he refused to grant conditions. They had prayed to be allowed to keep their arms; affecting to believe, like the Nervii, that they would be in danger from the Gauls if they were unable to defend themselves. Caesar undertook that they should have no hurt, but he insisted that their arms must be given up. They affected obedience. They flung their swords and lances over the walls till the ditch was filled with them. They opened their gates; the Romans occupied them, but were forbidden to enter, that there might be no plundering. It seems that there was a desperate faction among the Aduatuci who had been for fighting to extremity. A third part of the arms had been secretly reserved, and after midnight the tribe sallied with all their force, hoping to catch the Romans sleeping. Caesar was not to be surprised a second time. Expecting that some such attempt might be made, he had prepared piles of fagots in convenient places. These bonfires were set blazing in an instant. By their red light the legions formed; and, after a desperate but unequal combat, the Germans were driven into the town again, leaving 4,000 dead. In the morning the gates were broken down, and Namur was taken without more resistance. Caesar’s usual practice was gentleness. He honored brave men, and never punished bold and open opposition. Of treachery he made a severe example. Namur was condemned. The Aduatuci within its walls were sold into slavery, and the contractors who followed the army returned the number of prisoners whom they had purchased at 53,000. Such captives were the most valuable form of spoil.

The Belgae were thus crushed as completely as the Gauls had been crushed in the previous year. Publius Crassus had meanwhile made a circuit of Brittany, and had received the surrender of the maritime tribes. So great was the impression made by these two campaigns, that the Germans beyond the Rhine sent envoys with offers of submission. The second season was over. Caesar left the legions in quarters about Chartres, Orleans, and Blois. He himself returned to Italy again, where his presence was imperatively required. The Senate, on the news of his successes, had been compelled, by public sentiment, to order an extraordinary thanksgiving; but there were men who were anxious to prevent Caesar from achieving any further victories since Ariovistus had failed to destroy him.
