Before striking the camp all the immense booty taken in the campaign was burnt. The prisoners, most of them the peasantry of the district round Vienna, were massacred. Only the fairest of the young women were carried off captives to be sold as slaves. The Sultan returned to Constantinople. There was no pursuit of his army. It came back intact. It was a slur on the fame of Solyman that he endeavoured to conceal his failure to capture Vienna by lying accounts of success, and by a popular celebration of triumph, on return to his capital. There was this much to be said for him, that he had flouted the Austrians, by invading their country and devastating it up to the walls of Vienna, without any attempt, on their part, to meet him in the field or to follow him up on his retreat. Three years later, in 1532, Solyman, with another immense army, again invaded Hungary, with the avowed object of marching to Vienna and attacking the army of the Emperor. Charles V, on this occasion, took command of the Austrian army. It was expected that a trial of strength would take place between the two potentates, and would decide which of them was the stronger. But Solyman’s progress was delayed by the heroic defence for three weeks of the small fortress of Guns. After its capture Solyman made no further advance towards Vienna, but turned aside and devastated Styria, and then led his army homeward. The Emperor, on his part, made no effort to meet his foe and join conclusions with him. It was evident that both of them were anxious to avoid the issue of a great battle. Though the Sultan had retreated and had returned to Constantinople, peace was not concluded, and a desultory war was continued for some years between Ferdinand and Zapolya. Peace was concluded in 1538, under which Zapolya was to retain the title of King of Eastern Hungary and Transylvania and Ferdinand was acknowledged ruler of the western half. In 1566 Solyman again invaded Hungary, on his thirteenth and last campaign, to which we will revert later. We have thus described briefly the course of events between the Turks and the Hungarians, supported by Austria. Though the conquests of Solyman in this direction had been arrested by his failure to capture Vienna, he succeeded in securing virtual possession of the greater part of Hungary.
