プブリウス・デキウス・ムス
Unable to obtain a victory, Fabius withdrew the spearmen of the First Legion from the line and sent them under the command of Barbatus stealthily around the enemy flank into the hills behind, whence the latter had earlier descended. They were ordered to coordinate an attack from behind with an especially vigorous cavalry charge to the front of the Samnite line. The plan went entirely wrong: the charge came too soon and was repulsed. A counterattack was beginning to break the Roman line when Barbatus' men appeared on the hills and were mistaken for the second Roman army under Mus, a disaster for the Samnites if true. They abandoned the field posthaste leaving behind 23 standards and 3400 slain, while 830 were taken prisoner. In fact Publius Decius Mus was far away in south Samnium.
