At the end of the day Belisarius was everywhere successful; 20,000 Goths had fallen, and the self-confidence of Witiges was so broken that he never again tried a general assault. He relied instead on a blockade, but, though he inflicted great misery on the garrison, and still more on the populace, he never closed the roads or the river sufficiently to exclude occasional convoys of provisions. He did not prevent Belisarius from transferring to Campania the greater part of the women, aged men, and slaves in the city. Meanwhile the summer drew on, and the Gothic hosts began to suffer from malaria, and from the filthy state of the crowded camps. On the other hand, Belisarius at last began to receive reinforcements from Constantinople, and was able to make sallies, in which his horsemen handled the Gothic outposts very roughly. When both assault and blockade had been proved ineffectual, and when an attempt to creep into the city through the empty aqueducts had been foiled, Witiges would probably have done well to raise the siege, and throw on Belisarius, whose army was still very small, the burden of taking the offensive. Instead of doing this he lay obstinately in his camp for a year and nine days, watching his army melt away under the scourge of pestilence, and allowing the numbers and boldness of the Imperialists to increase. At last Belisarius had been so strongly reinforced that he was able, while still holding Rome, to put a second force in the field. This he sent, under an officer named John the Bloody, through the Sabine hills to make a dash into Picenum and menace Ravenna. [Sidenote: Siege of Rome raised, 538.] John, a very able officer, seized the important town of Rimini, only thirty-three miles from Ravenna, in February 538. The news that his capital was being threatened, and that the enemy was in his rear, at last forced the sluggish king of the Goths to move. He set his seven camps on fire, and retired up the Flaminian Way into Picenum. Thus the prudence and valour of Belisarius were at last vindicated, and the Romans, after a siege of 374 days, could once more breathe freely.
