[1] Titus Quinctius Pennus Capitolinus Crispinus was appointed dictator in 361 BC, most likely due to the presence of Gauls and their proximity to Rome.

They had encamped on the side of the Anio River farthest from the city near the Via Salaria, roughly 3 km north of the Colline Gate.

Upon being appointed dictator, Crispinus ordered that the courts be suspended and that all men of military qualifications join him to march north to the river.

He exploited the Gaul's size and snuck between his sword and body, leaving himself unexposed and delivering a decisive blow to his groin and stomach, killing his enemy and therefore deciding the result of the battle.

[5][6] The Gauls retreated east from the bridge to the town of Tibur, where they formed a military alliance with the Tiburtes, who provided them with supplies.
