In the meantime the other subject races of Hungary were preparing in their own way for resistance to the Magyars. The Croatian Assembly at Agram, finding themselves discouraged by the Emperor, were disposed to strengthen their union with the Serbs of Slavonia; and, on June 6, Gaj and Jellaciç both supported proposals at Agram for uniting the Serbs and Croats under one rule. Rajaciç, who happened to be passing through Agram, heartily responded to these proposals; and it was resolved that the relations between the Ban of Croatia and the Voyvode of the Serbs should be left to be settled at a later period. But the Serbs, though heartily desiring sympathy with the Croats, were not disposed to trust to alliances, however welcome, or to Constitutional arrangements, however ingenious, for the settlement of their grievances against the Magyars; for they, too, had been forced to abandon peaceable discussions for actual warfare. Crnojeviç, not having been found sufficiently stern in the Magyar service, was being driven into more violent courses by the addition of a fiercer subordinate; and the cruelties inflicted on the Serbs of the Bacska had so roused their kinsmen in other parts of Hungary that an old officer of the military frontier had crossed the Danube at the head of his followers and seized the town of Titel. At the same time the Serbs sent a deputation to Hrabowsky, the Governor of Peterwardein, to complain of the cruelties of the Magyar bands. Hitherto Hrabowsky had seemed to hesitate between the two parties; but he now grew angry in the conference with the Serb deputation, and disputed the right of the Serbs to stay in Hungary. The Serbs, alarmed at these threats, began once more to gather at Carlowitz; and they now tried to draw recruits from friendly neighbours. Stratimiroviç had succeeded in persuading some of the regiments from the frontier to take up the Serb cause; but he perhaps relied still more on the help of those Serbs from the principality of Servia, who were now flocking in across the border to defend their kinsmen against the Magyars. Of the leaders of these new allies the most important was General Knicsanin, who helped to organize the forces in Carlowitz. The Serbs of Carlowitz had, however, not yet entered upon actual hostilities, when, on June 11, during one of the meetings of their Assembly, Hrabowsky suddenly marched out of Neusatz, dispersed a congregation who were coming out of a chapel half way on the road between Neusatz and Carlowitz, and reached the latter town before the Serbs were aware of his intention. The Serbs, though taken by surprise, rushed out to defend their town, with a Montenegrin leader at their head. The contest continued for several hours; but at last Hrabowsky and his soldiers were driven back into Neusatz. Two days later ten thousand men were in arms in Carlowitz to defend their town and their race.
