That this new military organization was in the main a Roman, or at any rate Italian, remodelling and improvement of the old Hellenic tactics of the phalanx, is plain. If some germs of the system of reserve and of the individualizing of the smaller subdivisions of the army are found to occur among the later Greek strategists, especially Xenophon, this only shows that they felt the defectiveness of the old system, but were not well able to obviate it. The manipular legion appears fully developed in the war with Pyrrhus; when and under what circumstances it arose, whether at once or gradually, can no longer be ascertained. The first tactical system which the Romans encountered, fundamentally different from the earlier Italo-Hellenic system, was the Celtic sword-phalanx. It is not impossible that the subdivision of the army and the intervals between the maniples in front were arranged with a view to resist, as they did resist, its first and only dangerous charge; and it accords with this hypothesis that Marcus Furius Camillus, the most celebrated Roman general of the Gallic epoch, is presented in various detached notices as the reformer of the Roman military system. The further traditions associated with the Samnite and Pyrrhic wars are neither sufficiently accredited, nor can they with certainty be duly arranged;(23) although it is in itself probable that the prolonged Samnite mountain warfare exercised a lasting influence on the individual development of the Roman soldier, and that the struggle with one of the first masters of the art of war, belonging to the school of the great Alexander, effected an improvement in the technical features of the Roman military system.
