His brother Kálmán had reached Pest, and after urging the terrified inhabitants to abandon the city, cross the Danube, and hide wherever they could, he continued his journey to Slavonia (then Dalmatia and Croatia), his dukedom, where he soon after died of his wounds. Before the people of Pest could remove their goods to a place of safety, they were hemmed in by the Mongols. Thousands from the surrounding country had taken refuge here with their families and treasures, and the numbers had been further increased by the arrival of fugitives from the army. They resolved to defend themselves to the last man; but they little knew the enemy with whom they had to deal. Three days' battering with catapults was enough to make breaches in the walls; the Mongols stormed and burnt the town, and murdered all who fell into their hands. The Mongols flooded all the land east of the Danube, but for the present the broad river formed a barrier which they could not easily pass, and they were further deterred from making the attempt by the idea, unfortunately erroneous, that if they crossed it they would find all the armies of Europe massed upon the other side waiting to receive and beat them back. But if they were checked to the west, there was nothing to prevent their chasing the King, who was lingering near the Drave. Here they were in no fear of the armies of Europe, and they crossed the Danube by means of bladders and boats. Béla fled to Spalatro, but feeling unsafe even there, retired with his family to the island of Issa. Furious at finding that his prey had escaped him, the Mongol leader, Kajdán, revenged himself upon his prisoners, whom he set up in rows and cut down; then he hurried on to the sea coast, and appeared before Spalatro early in May. Foiled again, he hurried to Issa, which was connected with the mainland by a bridge; and here he had the mortification of seeing the King and his followers take ship for the island of Bua under his very eyes. Pursuit, without a fleet, was hopeless, and Kajdán had to content himself with ravaging Dalmatia, Croatia, and Bosnia. CHAPTER XV. DORA'S RESOLVE. For days, weeks, months, Talabor had been expecting Libor and his Mongols to return and renew their attack upon the castle, whose defences he had strengthened in every way possible to him. But spring had given way to summer, and summer to autumn, and still they had not come. When a winter of unusual severity set in, he felt the position safer, for the steep paths were blocked with snow or slippery with ice. Rumours of the fatal battle had not been long in reaching the castle, and fugitives had been seen by one or another of the villagers, whose accounts, though they differed in many respects, all agreed in this, that the country was in the hands of the Mongols, and that the King had fled for his life--whether he had saved it was doubtful. One reported the death of both the Szirmays, another declared that Master Peter had escaped with the King.
