In the case of certain cantons, such as the Nervii, the efficiency of their infantry is noticed as exceptional; it is remarkable that these had no cavalry, and perhaps were not even a Celtic but an immigrant German tribe.
But in general the Celtic infantry of this period appears as an unwarlike and unwieldy levy en masse; most of all in the more southern provinces, where along with barbarism valour had also disappeared.

The Celt, says Caesar, ventures not to face the German in battle.

The Roman general passed a censure still more severe than this judgment on the Celtic infantry, seeing that, after having become acquainted with them in his first campaign, he never again employed them in connection with Roman infantry.
Stage of Development of the Celtic Civilization If we survey the whole condition of the Celts as Caesar found it in the Transalpine regions, there is an unmistakeable advance in civilization, as compared with the stage of culture at which the Celts came before us a century and a half previously in the valley of the Po.

Then the militia, excellent of its kind, thoroughly preponderated in their armies;( 23) now the cavalry occupies the first place.

Then the Celts dwelt in open villages; now well- constructed walls surrounded their townships.
