This refusal left the Patricians in a quandary. With riot in the streets and war beyond the walls they were at the mercy of the commons. They were forced to promise a mitigation of the laws, declaring that no one should henceforth seize the goods of a soldier while he was in camp, or hinder a citizen from enlisting by keeping him in prison. This promise satisfied the people. The debtors' prisons were emptied, and their late tenants crowded with enthusiasm into the ranks. Through the gates the army marched, met the foe, and drove him in defeat from the soil of the Roman state. Victory gained, the Plebeians looked for laws to sustain the promises under which they had fought. They looked in vain; the senate took no action for their redress. But they had learned their power, and were not again to be enslaved. Their action was deliberate but decided. Taking measures to protect their homes on the Aventine Hill, they left the city the next year in a body, and sought a hill beyond the Anio, about three miles beyond the walls of Rome. Here they encamped, built fortifications, and sent word to their lordly rulers that they were done with empty promises, and would fight no more for the state until the state kept its faith. All the good of their fighting came to the Patricians, they said, and these might now defend themselves and their wealth. The senate was thrown into a panic by this decided action. When the hostile cities without should learn of it, they might send armies in haste to undefended Rome. The people left in the city feared the Patricians, and the Patricians feared them. All was doubt and anxiety. At length the senate, driven to desperation, sent an embassy to the rebels to treat for peace, being in deadly fear that some enemy might assail and capture the city in the absence of the bulk of its inhabitants. The messenger sent, Menenius Agrippa Lanatus, was a man famed for eloquence, and a popular favorite. In his address to the people in their camp he repeated to them the following significant fable: "At a time when all the parts of the body did not agree together, as they do now, but each had its own method and language, the other parts rebelled against the belly. They said that it lay quietly enjoying itself in the centre, while they, by care, labor, and service, kept it in luxury. They therefore conspired that the hands should not convey food to the mouth, the mouth receive it, nor the teeth chew it. They thus hoped to subdue the belly by famine; but they found that they and all the other parts of the body suffered as much. Then they saw that the belly by no means rested in sloth; that it supplied instead of receiving nourishment, sending to all parts of the body the blood that gave life and strength to the whole system."
