Of all men then living, Crassus was best entitled to command an army employed in fighting revolted slaves. If not the greatest slaveholder in Rome, he was the most systematic of the class of owners, and knew best how to turn the industry of slaves to account. He was the wealthiest citizen of the republic. One can understand how indignant such a person must have felt at the audacity of the gladiator and his followers. As a slaveholder, as a man of property, as a lover of law and order, he was concerned at so very disorderly a spectacle as that of slaves subverting all the laws of the republic; as a Roman, he felt that abhorrence for slaves which was common to the character. Here were motives enough to bring out the powers of any man, if powers he had in him; and it does not follow that because Crassus was very rich he was therefore a fool. He was a man of consummate talents, and at this particular time was probably the most influential citizen of Rome. The Romans had confidence in him, as the embodiment of the spirit of supremacy by which they were so completely animated. The event showed that their confidence was not misplaced. The army of Crassus was two hundred thousand strong, and having restored its discipline by examples of great severity, he marched to meet Spartacus; but on arriving in front of the latter's position, he would not attack it, while Spartacus showed an equal unwillingness to fight. The Roman determined to blockade the enemy. As they had the sea on one side, and that was held by a fleet, he commenced a line of works, the completion of which would have rendered it impossible for the gladiators to escape. These works were on the usual Roman scale, and consisted principally of walls and ditches, a hundred thousand men being employed in their construction. So cleverly did Crassus conceal what he was about, that it was not until he had almost accomplished his design that Spartacus discovered the intention of his foe. The emergency was suited to his genius, and he was not unequal to it. He began a series of attacks on the Romans, harassing them perpetually, retarding their labors, and drawing their attention from that point of their line by which he purposed to extricate his army. At last, on a night when a terrible snow-storm was raging, he led his men to a place where the Roman works were yet incomplete, the snow enabling them to march noiselessly. When they reached the line, the immense ditches seemed to bar their further advance; but they set resolutely at work to fill them. Earth, snow, fagots, and dead bodies of men and beasts were hastily thrown into them; and across this singular bridge the whole army poured into the country, leaving the Roman camp behind, and having rendered nugatory all the laborious digging and trenching of the legions.
