Nearly all are soon defeated, and sue for mercy. The Nervii, true to the German blood in their, veins, swear to die rather than surrender. They, at least, are worthy of their cause. Caesar advances against them at the head of eight legions. Drawn up on the banks of the Sambre, they await the Roman's approach. In three days' march Caesar comes up with them, pitches his camp upon a steep hill sloping down to the river, and sends some cavalry across. Hardly have the Roman horsemen crossed the stream, than the Nervii rush from the wooded hill-top, overthrow horse and rider, plunge in one great mass into the current, and, directly afterwards, are seen charging up the hill into the midst of the enemy's force. "At the same moment," says the conqueror, "they seemed in the wood, in the river, and within our lines." There is a panic among the Romans, but it is brief. Eight veteran Roman legions, with the world's victor at their head, are too much for the brave but undisciplined Nervii. Snatching a shield from a soldier, and otherwise unarmed, Caesar throws himself into the hottest of the fight. The battle rages foot to foot and hand to hand but the hero's skill, with the cool valor of his troops, proves invincible as ever. The Nervii, true to their vow, die, but not a man surrenders. They fought upon that day till the ground was heaped with their dead, while, as the foremost fell thick and fast, their comrades, says the Roman, sprang upon their piled-up bodies, and hurled their javelins at the enemy as from a hill. They fought like men to whom life without liberty was a curse. They were not defeated, but exterminated. Of many thousand fighting men went home but five hundred. Upon reaching the place of refuge where they had bestowed their women and children, Caesar found, after the battle, that there were but three of their senators left alive. So perished the Nervii. Caesar commanded his legions to treat with respect the little remnant of the tribe which had just fallen to swell the empty echo of his glory, and then, with hardly a breathing pause, he proceeded to annihilate the Aduatici, the Menapii, and the Morini.
