Ab urbe condita

art of war, which from the beginning of the City had been an unbroken tradition, had now grown into a science based on definite and permanent rules. It was thus that the kings conducted their wars, and alter them the Junii and the Valerii, who expelled the kings, and in later succession the Fabii, the Quinctii, and the Cornelii.

It was these rules that Camillus followed, and the men who would have had to fight with Alexander had seen Camillus as an old man when they were little more than boys. Alexander no doubt did all that a soldier ought to do in battle, and that is not his least title to fame.
