charge, which, such was the number of the Goths in the road and the confusion of their advance, was successful. The barbarians fled and Belisarius and his gallant troopers entered the City at nightfall. [Footnote 1: Procopius tells us both that Vitiges advanced through the Sabine country and that he crossed the Tiber--an impossible thing. Gibbon and Hodgkin refuse the former, Gregorovius the latter statement. I agree with Gregorovius, for Procopius confuses the Tiber and Anio elsewhere, notably iii. 10.] [Footnote 2: Possibly the Porta Pinciana.] [Illustration: Sketch Map of VITIGES, MARCH] All through that night the walls of Rome were aflame with watchfires and disastrous tidings, happily false; and when the dawn rose out of the Campagna, Rome was still inviolate. Thus began the first siege of Rome in the early days of March 537. It lasted for three hundred and seventy-four days and ended in the sullen retreat of the barbarians to save Ravenna, which as Vitiges had at first foreseen would happen was threatened with attack. But as so often in later times, those three hundred and seventy-four days had dealt incomparably more hardly with the besiegers than with the besieged. The Campagna had done its work, and it has been calculated that of the 150,000 men that are said to have marched with Vitiges to attack the city, not more than 10,000 returned to Ravenna. Meanwhile during the great siege Belisarius, by means of his subordinate general, John, had carried on a campaign in Picenum and had been able to send assistance to the people of Milan, eagerly Roman as they were. In Picenum, John had perhaps rashly pushed forward from Ancona to Rimini; which he held precariously and to the danger of Ancona. The first act of Belisarius after the raising of the siege of the City was to despatch troops post haste to Rimini. He sent Ildiger and Martin with a thousand horse to fight their way if necessary to Rimini to withdraw John and his two thousand horse. He purposed to hold Rimini only with the tips of his fingers, for his determination was to secure all he held before he entered upon a final and a real advance northward. The position of Belisarius seemed more insecure than in fact it was. If we consider the great artery of his advance northward, the Via Flaminia, we shall find that he held everything to the east of the road between Rome and Ancona save one fortress, Osimo above Ancona, which was held by four thousand of the enemy. But all was or seemed to be insecure because he held nothing to the west of the great road save Perugia: Orvieto, Todi, Chiusi, Urbino were all in Gothic hands, while the Furlo Pass over the Apennines was also held by the enemy.
