Plutarch Crassus 9

[1] To begin with, the gladiators repulsed the soldiers who came against them from Capua, and getting hold of many arms of real warfare, they gladly took these in exchange for their own, casting away their gladiatorial weapons as dishonourable and barbarous. Then Clodius the praetor was sent out from Rome against them with three thousand soldiers, and laid siege to them on a hill which had hut one ascent, and that a narrow and difficult one, which Clodius closely watched;

[2] everywhere else there were smooth and precipitous cliffs. But the top of the hill was covered with a wild vine of abundant growth, from which the besieged cut off the serviceable branches, and wove these into strong ladders of such strength and length that when they were fastened at the top they reached along the face of the cliff to the plain below. On these they descended safely, all but one man, who remained above to attend to the arms. When the rest had got down, he began to drop the arms, and after he had thrown them all down, got away himself also last of all in safety.

[3] Of all this the Romans were ignorant, and therefore their enemy surrounded them, threw them into consternation by the suddenness of the attack, put them to flight, and took their camp. They were also joined by many of the herdsmen and shepherds of the region, sturdy men and swift of foot, some of whom they armed fully, and employed others as scouts and light infantry.

[4] In the second place, Publius Varinus, the praetor, was sent out against them, whose lieutenant, a certain Furius, with two thousand soldiers, they first engaged and routed; then Spartacus narrowly watched the movements of Cossinius, who had been sent out with a large force to advise and assist Varinus in the command, and came near seizing him as he was bathing near Salinae.

[5] Cossinius barely escaped with much difficulty, and Spartacus at once seized his baggage, pressed hard upon him in pursuit, and took his camp with great slaughters Cossinius also fell. By defeating the praetor himself in many battles, and finally capturing his lictors and the very horse he rode, Spartacus was soon great and formidable; but he took a proper view of the situation, and since he could not expect to overcome the Roman power, began to lead his army toward the Alps, thinking it necessary for them to cross the mountains and go to their respective homes, some to Thrace, and some to Gaul.

[6] But his men were now strong in numbers and full of confidence, and would not listen to him, but went ravaging over Italy. It was now no longer the indignity and disgrace of the revolt that harassed the senate, but they were constrained by their fear and peril to send both consuls into the field, as they would to a war of the utmost difficulty and magnitude.

[7] Gellius, one of the consuls, fell suddenly upon the Germans, who were so insolent and bold as to separate themselves from the main body of Spartacus, and cut them all to pieces; but when Lentulus, the other consul, had surrounded the enemy with large forces, Spartacus rushed upon them, joined battle, defeated the legates of Lentulus, and seized all their baggage. Then, as he was forcing his way towards the Alps, he was met by Cassius, the governor of Cisalpine Gaul, with an army of ten thousand men, and in the battle that ensued, Cassius was defeated, lost many men, and escaped himself with difficulty.
