The Romans showed their confidence in their power to resist a siege by at once despatching Marcellus with his ten thousand men to Canusium. Thus, with a strongly defended city in front, an army of twenty thousand Roman soldiers, which would speedily increase to double that number, in his rear, Hannibal perceived that were he to undertake the siege of Rome he would risk all the advantages he had gained. He determined, therefore, to continue the policy which he had laid down for himself, namely, to move his army to and fro among the provinces of Italy until the allies of Rome one by one fell away from her, and joined him, or until such reinforcements arrived from Carthage as would justify him in undertaking the siege of Rome.

Rome herself was never grander than in this hour of defeat; not for a moment was the courage and confidence of her citizens shaken. The promptness with which she prepared for defence, and still more the confidence which she showed by despatching Marcellus with his legion to Canusium instead of retaining him for the defence of the city, show a national spirit and manliness worthy of the highest admiration. Varro was ordered to hand over his command to Marcellus, and to return to Rome to answer before the senate for his conduct.
