Two days after Hannibal broke through the Roman positions round the plains of Campania he intrusted Malchus with an important commission.

Commanding the bodyguard of the general, and being closely related to him, Malchus was greatly in Hannibal's confidence, and was indeed on the same footing with Mago, Hannibal's brother, and two or three other of his most trusted generals.

Gathered in the general's tent on the previous evening, these had agreed with their leader that final success could not be looked for in their enterprise unless reinforcements were received from Carthage.
It was now a year since they had emerged from the Alps on to the plains of Northern Italy.

They had annihilated two Roman armies, had marched almost unopposed through some of the richest provinces of Italy, and yet they were no nearer the great object of their enterprise than they were when they crossed the Alps.
Some of the Cisalpine Gauls had joined them, but even in the plains north of the Apennines the majority of the tribes had remained firm to their alliance with the Romans, while south of that range of mountains the inhabitants had in every case shown themselves bitterly hostile.
Everywhere on the approach of the Carthaginians they had retired to their walled towns, which Hannibal had neither the time nor the necessary machines to besiege.
Although Rome had lost two armies she had already equipped and placed in the field a third force superior in number to that of the Carthaginians; her army in Spain had not been drawn upon; her legion north of the Apennines was operating against the revolted tribes; other legions were in course of being raised and equipped, and Rome would take the field in the spring with an army greatly superior in strength to that of Carthage.

Victorious as Hannibal had been in battle, the army which had struggled through the Alps had in the year which had elapsed, greatly diminished in numbers.
