In this emergency C. Marcius Rutilus was nominated Dictator —the first Dictator nominated from the plebs —and he appointed as Master of the Horse C. Plautius, also a plebeian. The patricians were indignant at even the dictatorship becoming common property, and they offered all the resistance in their power to any decree being passed or any preparations made to help the Dictator in prosecuting that war.
This only made the people more ready to adopt every proposal which the Dictator made.
On leaving the City he marched along both banks of the Tiber, ferrying the troops across in whichever direction the enemy were reported to be; in this way he surprised many of the raiders scattered about the fields. Finally he surprised and captured their camp; 8ooo prisoners were taken, the rest were either killed or hunted out of the Roman territory.
By an order of the people which was not confirmed by the senate a triumph was awarded him.
As the senate would not have the elections conducted by a plebeian Dictator or a plebeian consul, they fell back on an interregnum. There was a succession of interreges —Q. Servilius Ahala, M. Fabius, Cn. Manlius, C. Fabius, C. Sulpicius, L. Aemilius, Q. Servilius, and M. Fabius Ambustus.
In the second of these interregna a contest arose because two patrician consuls were elected. When the tribunes interposed their veto and appealed to the Licinian Law, Fabius, the interrex, said that it was laid down in the Twelve Tables that whatever was the last order that the people made that should have the force of law, and the people had made an order by electing the two consuls.
The tribunes' veto only availed to postpone the elections, and ultimately two patrician consuls were elected, namely C. Sulpicius Peticus (for the third time) and M. Valerius Publicola. They entered upon their office the day they were elected.
