The united Hussite forces marched to Moravia immediately after the treaty of Vožic. They first undertook to relieve the city of Třebice, which was then besieged by King Sigismund and his son-in-law. On the news of the approach of the Hussites Sigismund, cautious as usual, retired from the camp before Třebice and was contented with burning down many villages belonging to Utraquist nobles in the vicinity of Brno. Somewhat later Sigismund’s son-in-law, Albert of Austria, also retired in the direction of Hungary. Not heeding these enemies on their flank the Bohemians, under Prince Korybutovič and Bohuslav of Schwamberg, after occupying the city of Znoymo, crossed the Austrian frontier. The warfare in this borderland had a distinctly racial character. The inveterate antipathy between the Austrian and the Bohemian, which still exists, already prevailed in those remote days. The attack on Austria is noteworthy, as being one of the earliest instances of the system of offensive warfare which the Bohemians adopted during the last part of the Hussite wars. The Bohemians besieged the town and castle of Retz in Lower Austria. The city was obstinately defended by the Austrians, under John of Hardegg, Count of Retz, who, though of great age, displayed youthful energy, as the contemporary chroniclers tell us. The Hussite losses were very considerable, and Bohuslav of Schwamberg received a severe wound, in consequence of which he died shortly afterwards. The city at last capitulated on November 25. The Count of Retz was treated with the comparative leniency which usually distinguished the Utraquists from their Romanist antagonists. He was conducted to Prague, where he remained in honourable captivity. Many of the Austrian soldiers were, however, killed by the Hussites, who were exasperated by the loss of their leader, Bohuslav of Schwamberg. We have unfortunately but very scant information with regard to this important campaign.[1]
