The pay of the Roman army for that year was furnished by the enemy; and two tunics for each soldier were exacted from them: this was the purchase of the truce.

The tranquillity now established in Etruria was interrupted by a sudden insurrection of the Umbrians, a nation which had suffered no injury from the war, except what inconvenience the country had felt in the passing of the army.

These, by calling into the field all their own young men, and forcing a great part of the Etrurians to resume their arms, made up such a numerous force, that speaking of themselves with ostentatious vanity and of the Romans with contempt, they boasted that they would leave Decius behind in Etruria, and march away to besiege Rome; which design of theirs being reported to the consul Decius, he removed by long marches from Etruria towards their city, and sat down in the district of Pupinia, in readiness to act according to the intelligence received of the enemy.

Nor was the insurrection of the Umbrians slighted at Rome: their very threats excited tears among the people, who had experienced, in the calamities suffered from the Gauls, how insecure a city they inhabited.

Deputies were therefore despatched to the consul Fabius with directions, that, if he had any respite from the war of the Samnites, he should with all haste lead his army into Umbria.
