The patrician envoys negotiated a settlement to the dispute, first by agreeing to debt relief, and then by creating the new and sacrosanct office of the Tribune of the Plebs, in order to protect the interests of the plebeians.
Marcius led a company of soldiers through the gates of Corioli before they could be closed, and set fire to a number of buildings, effecting the capture of the undefended populace, and winning resounding fame, as well as the surname of Coriolanus.
Believing his life in danger, he fled into exile amongst the Volsci, the very people whom he had helped to defeat, where he was sheltered by the Volscian leader, Attius Tullius.
As surprise and fear turned to anger, Tullius met them at a grove sacred to the goddess Ferentina, further inflaming their passions, and inducing the Volsci to declare war on Rome.
[8][9][10][11][12] Command of the Volscian forces was jointly entrusted to Tullius and Coriolanus, who led their army against Roman towns, colonies and allies.
Coriolanus was still of mind to refuse them, until one of his friends informed him that among the women were his mother, Veturia, his wife, Volumnia, and his two young sons.
On a subsequent occasion, Tullius arranged for an alliance between the Volsci and the Aequi, intending to renew hostilities upon Rome with a combined army.
