He convinced the Assembly of his sincerity by issuing an edict that none should keep a Roman citizen in chains or duress whereby he would be prevented from enrolling for military service, none should distrain or sell the goods of a soldier as long as he was in camp, or detain his children or grandchildren.
On the promulgation of this edict those debtors who were present at once gave in their names for enrolment, and crowds of persons running in all quarters of the City from the houses where they were confined, as their creditors had no longer the right to detain them, gathered together in the Forum to take the military oath.
These formed a considerable force, and none were more conspicuous for courage and activity in the Volscian war. The consul led his troops against the enemy and encamped a short distance from them.
The very next night the Volscians, trusting to the dissensions amongst the Romans, made an attempt on the camp, on the chance of desertions taking place, or the camp being betrayed, in the darkness.
The outposts perceived them, the army was aroused, and on the alarm being sounded they rushed to arms, so the Volscian attempt was foiled; for the rest of the night both sides kept quiet. The following day, at dawn, the Volscians filled up the trenches and attacked the rampart.
