Sulla's March on Rome
On these views he acted. He assembled his soldiers--there were six legions, or about 35,000 men--and explained to them the summons that had arrived from Rome, not forgetting to hint that the new commander- in-chief would undoubtedly lead to Asia Minor not the army as it stood, but another formed of fresh troops. The superior officers, who still had more of the citizen than the soldier, kept aloof, and only one of them followed the general towards the capital; but the soldiers, who in accordance with earlier experiences(23) hoped to find in Asia an easy war and endless booty, were furious; in a moment the two tribunes that had come from Rome were torn in pieces, and from all sides the cry arose that the general should lead them to Rome.
23. Cf. III. XI. Squandering of the Spoil
Without delay the consul started, and forming a junction with his like-minded colleague by the way, he arrived by quick marches--little troubling himself about the deputies who hastened from Rome to meet and attempted to detain him--beneath the walls of the capital. Suddenly the Romans beheld columns of Sulla's army take their station at the bridge over the Tiber and at the Colline and Esquiline gates; and then two legions in battle array, with their standards at their head, passed the sacred ring-wall within which the law had forbidden war to enter. Many a worse quarrel, many an important feud had been brought to a settlement within those walls, without any need for a Roman army breaking the sacred peace of the city; that step was now taken, primarily for thesake of the miserable question whether this or that officer was called to command in the east.
