Nevertheless these “allies” were more sensible of the liberties they had lost than of the rights they had gained by coming under the expanding wing of Rome. The latter part of the fourth century shows the growing state embarked upon a terrific struggle which lasted on and off from summer to summer for nearly fifty years. Her principal foes were the warlike Samnites of the Southern Apennines, closely akin, it seems, to the dominant race at Rome. This tremendous conflict is clearly the turning-point of Roman history. At various stages nearly all the peoples of Italy rose and enrolled themselves among the enemy, the Latins, the Etruscans, the Umbrians, the Marsi, the Gauls (for they too were brought in again by the Etruscans in their last efforts for freedom) and the Samnites themselves, a race of born fighters under competent generals. Once, in 321 B.C., both consuls and the entire army of Rome were entrapped at the Caudine Pass, but Rome never thought of surrender. Doggedly her Senate refused to know when it was beaten and continued the struggle. Fortunately it was one purpose against many, and Rome beat her enemies in detail until she was able to emerge victorious. The history of that great conflict has come down to us in an incomplete state full of fairy-tales and omissions, but it is clear that the Roman Senate showed extraordinary resolution and tenacity, as it did in the next century against foreign enemies. Beaten to its knees again and again it refused any terms of peace short of victory. That is a marvellous thing, if Rome was really one among many towns of Latium. It is to be noted that this was the war in which she learnt the new system of fighting whereby she was fated to conquer the world. Hitherto in ancient warfare a battle array had meant a solid line in which the men stood shoulder to shoulder in several ranks, pressing on with spear and shield against a similar line of the enemy. It was largely a question of weight in the impact. You tried to make your line deep enough to prevent yielding and long enough to envelop the enemy’s flank: once you could turn or break the enemy’s line victory was yours. But the Romans, either because they were often outnumbered on the field of battle, or, as some say, in fighting the Gallic warriors with their long swords, found it necessary to fight not shoulder to shoulder but in open order--not in a solid phalanx but in open companies or “maniples.” This had a far-reaching effect: it made every Roman soldier a self-reliant unit, who could fence skilfully with his favourite weapon, the sword, instead of merely pushing a long pike as his neighbours did. It is clear that only an army of natural soldiers could have adopted such an innovation successfully. Once established, it made the Roman soldier invincible. The maniple of 200 men was not only far more mobile than a solid phalanx, but it covered a length of ground equal to that of three times its own numbers. Formerly only the front rank--the
