Camillus was accused of having taken more than his proper share of the spoil of Veii, in especial a brass door from a temple.

His friends offered to pay any fine that might be laid on him, but he was too proud to stand his trial, and chose rather to leave Rome.

As he passed the gates, he turned round and called upon the gods to bring Rome to speedy repentance for having driven him away.
Even then the Gauls were in the midst of a war with Clusium, the city of Porsena, and the inhabitants sent to beg the help of the Romans, and the senate sent three young brothers of the Fabian family to try to arrange matters.

They met the Gaulish Bran or chief, whom Latin authors call Brennus, and asked him what was his quarrel with Clusium or his right to any part of Etruria.

Brennus answered that his right was his sword, and that all things belonged to the brave, and that his quarrel with the men of Clusium was, that though they had more land than they could till, they would not yield him any.
