As a sign of good faith, the Romans gave ten boys and ten girls (one of whom was Publicola's daughter, Valeria) to Lars Porsena as hostages. The girls escaped and managed to get back to Rome, but when Publicola found out he had them returned to Lars Porsena. On the way, they were captured by Tarquin's forces, but Valeria escaped. The other girls were rescued by Lars Porsena.
Publicola was elected consul again for the next year (506). Some of the Sabines started arguing for peace with Rome. Although they were not successful in getting this policy adopted, Publicola did manage to persuade one of its leading proponents, Attius Clausus, who was very rich and powerful, to come over to Rome (505). He did so together with five thousand Sabine families, and adopted the more Roman-sounding name of Appius Claudius.
The next year (504), Publicola died. He left so little in his will that it was not even enough to pay for his burial so he was given a state funeral.
