Some have written that Saguntum was taken in the eighth month after it began to be besieged; that Hannibal then retired to New Carthage, into winter quarters; and that in the fifth month after he had set out from Carthage he arrived in Italy.

If this be so, it was impossible that Publius Cornelius and Tiberius Sempronius could have been consuls, to whom both at the beginning of the siege the Saguntine ambassadors were despatched, and who, during their office, fought with Hannibal; the one at the river Ticinus, and both some time after at the Trebia.
Either all these events took place in a somewhat shorter period, or Saguntum was not begun to be besieged, but taken at the beginning of the year in which Publius Cornelius and Tiberius Sempronius were consuls.

For the battle at Trebia could not have been so late as the year of Cneius Servilius and Caius Flaminius, since Flaminius entered on the office at Ariminum, having been created by the consul Tiberius Sempronius; who, having repaired to Rome after the battle at Trebia for the purpose of creating consuls, returned when the election was finished to the army into winter quarters.

Nearly about the same time, both the ambassadors who had returned from Carthage brought intelligence to Rome that all appearances were hostile, and the destruction of Saguntum was announced.

Then such grief, and pity for allies so undeservingly destroyed, and shame that aid was withheld, and rage against the Carthaginians, and fear for the issue of events, as if the enemy were already at the gates, took at once possession of the senators, that their minds, disturbed by so many simultaneous emotions, trembled with fear rather than deliberated.
