In the Roman army the two consuls possessed equal authority. Agrippa, however, voluntarily resigned the supreme command to his colleague —a very beneficial arrangement where matters of great importance are concerned —and the latter, thus preferred by the ungrudging self-suppression of his colleague, courteously responded by imparting to him his plans, and treating him in every way as his equal.

When drawn up in battle order, Quinctius commanded the right wing, Agrippa the left. The centre was assigned to Sp. Postumius Albus, lieutenant-general; the other lieutenant-general, P. Sulpicius, was given charge of the cavalry.

The infantry on the right wing fought splendidly, but met with stout resistance on the side of the Volscians.

P. Sulpicius with his cavalry broke the enemy's centre. He could have got back to the main body before the enemy reformed their broken ranks, but he decided to attack from the rear, and would have scattered the enemy in a moment, attacked as they were in front and rear, had not the cavalry of the Volscians and Aequi, adopting his own tactics, intercepted him and kept him for some time engaged.

He shouted to his men that there was no time to lose, they would be surrounded and cut off from their main body if they did not do their utmost to make a finish of the cavalry fight;

it was not enough simply to put them to flight, they must dispose of both horses and men, that none might return to the field or renew the fighting. They could not resist those before whom a serried line of infantry had given way. His words did not fall on deaf ears.
