The new law does not appear to have made mention of the Plebs and its tribunes, for they were hardly a part of the constitution; and yet, in the crisis that followed the fall of the decemvirate, the question that gathered round these ignored powers was great enough to obscure every other issue. The Plebs might have been satisfied with the compromise, had it not been for the unfortunate attempt at despotism made by the second board of decemvirs. It is impossible to believe that this usurpation was really countenanced by the Patriciate, and that they aimed at staving off indefinitely the inevitable assaults of the Plebeians on the magistracy by indefinitely perpetuating this rule of ten annual commissioners without appeal; but they tolerated their rule, and backed up their excuses for not retiring, until two acts of tyranny raised mutinies in both the Roman camps. The plebeian soldiers cast off their allegiance to the ruling board, and first, under military leaders of their own choosing, occupied the Aventine; they then, accompanied by the majority of the unarmed Plebeians of Rome, wended their way a second time to the Mons Sacer (449 B.C.). The Senate in alarm sent two of its members, Valerius and Horatius, who were of good repute among the Plebs, to ask their wishes. The answer was: amnesty for the breach of military discipline involved in the secession; the restoration of the _provocatio_ (which meant the dissolution of the decemvirate) and of the tribunician power.[414] The demands had not increased since the first secession; protection was all that the Plebeians yet demanded.
