Note 1 — Chapter IV

The Romans, who understood and respected the right of war more than any other nation on earth, carried their scruples on this head so far that a citizen was not allowed to serve as a volunteer without engaging himself expressly against the enemy, and against such and such an enemy by name. A legion in which the younger Cato was seeing his first service under Popilius having been reconstructed, the elder Cato wrote to Popilius that, if he wished his son to continue serving under him, he must administer to him a new military oath, because, the first having been annulled, he was no longer able to bear arms against the enemy. The same Cato wrote to his son telling him to take great care not to go into battle before taking this new oath. I know that the siege of Clusium and other isolated events can be quoted against me; but I am citing laws and customs. The Romans are the people that least often transgressed its laws; and no other people has had such good ones.
