 Ergavica, another Celtiberian city, was alarmed about the defeats of its neighbours and opened its gates to the Romans.In addition, Gracchus defeated 20,000 Celtiberians who were besieging the city of Caravis (Magallon, in north-western Aragon), an ally of Rome, and conquered the city of Complega.Livy thought that some of the surrenders were in bad faith because whenever Gracchus left hostilities resumed and there was also a major battle near Mons Chaunus (probably Moncayo Massif) with many casualties on both sides.
