As to the fate of the general himself no
certain information was ever obtained. A small division alone was
conducted by Gaius Marcius, an excellent officer of the school of
Gnaeus, in safety to the other bank of the Ebro; and thither the
legate Titus Fonteius also succeeded in bringing safely the portion
of the corps of Publius that had been left in the camp; most even of
the Roman garrisons scattered in the south of Spain were enabled to
flee thither.
In all Spain south of the Ebro the Phoenicians ruled
undisturbed; and the moment seemed not far distant, when the river
would be crossed, the Pyrenees would be open, and the communication
with Italy would be restored. But the emergency in the Roman camp
called the right man to the command. The choice of the soldiers,
passing over older and not incapable officers, summoned that Gaius
Marcius to become leader of the army; and his dexterous management
and quite as much perhaps, the envy and discord among the three
Carthaginian generals, wrested from these the further fruits of their
important victory.
