The force with which the consuls had taken the field consisted of four legions and a large body of cavalry, in addition to 1000 picked Campanian troopers detailed for this war, whilst the contingents furnished by the allies and the Latin League formed an even larger army than the Roman army.
But in addition to this large force two other armies were stationed not far from the City, confronting Etruria; one in the Faliscan district, another in the neighbourhood of the Vatican. The propraetors, Cnaeus Fulvius and L. Postumius Megellus, had been instructed to fix their standing camps in those positions.
