Thus began, a few months after the death of Drusus, in the winter of 663-4, the struggle--as one of the coins of the insurgents represents it--of the Sabellian ox against the Roman she-wolf. Both sides made zealous preparations: in Italia great stores of arms, provisions, and money were accumulated; in Rome the requisite supplies were drawn from the provinces and particularly from Sicily, and the long-neglected walls were put in a state of defence against any contingency. The forces were in some measure equally balanced. The Romans filled up the blanks in their Italian contingents partly by increased levies from the burgesses and from the inhabitants--already almost wholly Romanized-- of the Celtic districts on the south of the Alps, of whom 10,000 served in the Campanian army alone,(13) partly by the contingents of the Numidians and other transmarine nations; and with the aid of the free cities in Greece and Asia Minor they collected a war fleet.(14) On both sides, without reckoning garrisons, as many as 100,000 soldiers were brought into the field,(15) and in the ability of their men, in military tactics and armament, the Italians were nowise inferior to the Romans. Subdivision of the Armies on Either Side The conduct of the war was very difficult both for the insurgents and for the Romans, because the territory in revolt was very extensive and a great number of fortresses adhering to Rome were scattered up and down in it: so that on the one hand the insurgents found themselves compelled to combine a siege-warfare, which broke up their forces and consumed their time, with the protection of an extended frontier; and on the other hand the Romans could not well do otherwise than combat the insurrection, which had no proper centre, simultaneously in all the insurgent districts. In a military point of view the insurgent country fell into two divisions; in the northern, which reached from Picenum and the Abruzzi to the northern border of Campania and embraced the districts speaking Latin, the chief command was held on the Italian side by the Marsian Quintus Silo, on the Roman side by Publius Rutilius Lupus, both as consuls; in the southern, which included Campania, Samnium, and generally the regions speaking Sabellian, the Samnite Gaius Papius Mutilus commanded as consul of the insurgents, and Lucius Julius Caesar as the Roman consul. With each of the two commanders-in-chief there were associated on the Italian side six, on the Roman side five, lieutenant-commanders, each of whom conducted the attack or defence in a definite district, while the consular armies were destined to act more freely and to strike the decisive blow. The most esteemed Roman officers, such as Gaius Marius, Quintus Catulus, and the two consulars of experience in the Spanish war, Titus Didius and Publius Crassus, placed themselves at the disposal of the consuls for these posts; and though the Italians had not names so celebrated to oppose to them, yet the result
