Once the battle was engaged, the left wing began to falter and Decius Mus called upon the Pontifex Maximus, M. Valerius, to tell him the means by which to save the army. The pontifex prescribed the required ritual acts and a prayer (see "devotio"). After performing the ritual, the fully armored Decius Mus plunged his horse into the enemy with such supernatural vigor and violence that the awe-struck Latins soon refused to engage him, eventually bringing him down with darts. Even then, the Latins avoided his body, leaving a large space around it, and the left wing of the Romans, once faltering, now swept into this weakness in the enemy lines. Manlius, conducting the right wing, held fast, allowing the Latins to use up their reserves, before crushing the enemy host between the renewed left and Samnite foederati at their flank, leaving only a quarter of the enemy to flee.
