Without the hope of reUef, the defence of Sirmium was prolonged above three years ; the walls were still untouched ; [AD. 581] but famine was inclosed within the walls, till a merciful capitu- lation allowed the escape of the naked and hungry inhabitants. Singidunum, at the distance of fiftj^ miles, experienced a more cruel fate : the buildings were rased, and the vanquished people was condemned to servitude and exile. ^" Yet the ruins of Sir- mium are no longer visible ; the advantageous situation of Singidunum soon attracted a new colony of Sclavonians ; and the conflux of the Save and Danube is still guarded by the fortifications of Belgrade, or the While (aIi/, so often and so obstinately disputed by the Christian and Turkish arms.^^ From Belgrade to the walls of Constantinople a line may be measured of six hundred miles : that line was marked with flames and with blood ; the horses of the Avars were alternately bathed in the Euxine and the Adriatic ; and the Roman pontiff, alarmed by the approach of a more savage enemy, •'•' was reduced to cherish the Lombards as the protectors of Italy. The despair of a captive, whom his country refused to ransom, disclosed to the Avars the invention and practice of military engines ; ***^ but in the first attempts they were rudely framed and awkwardly managed ; and the resistance of Diocletianopolis and Beroea, of [A.D.

The warfare of Baian was that of a Tartar, yet his mind was susceptible of a humane and generous sentiment ; he spared Anchialus, whose salutary waters had restored the health of the best beloved of his wives ; and the Romans confess that their starving army was fed and dismissed by the liberality of a foe.
