As the war was such a serious one, the Dictator vowed, in the form of words prescribed by the Pontifex Maximus, A. Cornelius, to celebrate the Great Games if he were victorious.
He formed the army into two divisions, one of which he assigned to the consul Quinctius, and their joint force advanced up to the enemies' position.
As they saw that the hostile camps were separated by a short distance from each other, they also formed separate camps, about a mile from the enemy, the Dictator fixing his in the direction of Tusculum, the consul nearer Lanuvium. The four armies had thus separate entrenched positions,
with a plain between them broad enough not only for small skirmishes, but for both armies to be drawn out in battle order.
Ever since the camps had confronted each other there had been no cessation of small fights, and the Dictator was quite content for his men to match their strength against the enemy, in order that through the issues of these contests they might entertain the hope of a decisive and final victory. The enemy, hopeless of winning a regular battle, determined to stake everything on the chances of a night attack on the consul's camp.
The shout which suddenly arose not only startled the consul's outposts and the whole army, but even woke the Dictator.
