Camillus

Now had the Gauls, after this battle, followed hard upon the fugitives, naught would have hindered Rome from being utterly destroyed and all those who remained in her from perishing, such was the terror which the fugitives infused into the occupants of the city, and with such confusion and delirium were they themselves once more filled.

But as it was, the Barbarians could not realize the magnitude of their victory, and in the excess of their joy, turned to revelry and the distribution of the good things captured in their enemy’s camp. For this reason the throngs who were for abandoning the city had ample time for flight, and those who were for remaining plucked up hope and prepared to defend themselves. Abandoning the rest of the city, they fenced the Capitol with ramparts and stocked it with missiles.
