Notwithstanding the truce of Amasia, guerilla raids on both sides continued all along the Hungarian frontiers. To check the incursions of the Heydons, Touighoun, the Pasha of Buda,[286] attacked and took Babocsa; and Ali, his successor, the victor of Fülek, with the same object, commenced the siege of Szigeth, on May 24, 1556, and assaulted the place a month later, but was repulsed with heavy loss. In the meantime the Palatine Nadasty had besieged Babocsa, and Ali hastened with a detachment to relieve it, but was defeated with great loss on the river Rinya (July 25). Babocsa was then abandoned by the Turks, and fell into the hands of the Hungarians, who burnt it, and blew up the citadel. Ali resumed the siege of Szigeth, but was so weakened by his defeat, that he was obliged to raise it, retreating to Buda, where he died soon afterwards.[287] The fall of Szigeth was thus postponed for ten years, when it was destined to be associated with the termination of a more glorious career, and the extinction of a more famous name.[288] Meanwhile Transylvania had again passed into the possession of Isabella and her son. She had at first gone to the Silesian duchies, which Ferdinand had given in exchange for Transylvania; but she was dissatisfied with them, and returned to her brother’s court in Poland, where she entered into correspondence with her partisans in Transylvania. The current of feeling there ran strongly in her favour. The Spaniard, Castaldo, Ferdinand’s governor, was ignorant of the national laws and usages. His troops were left unpaid, and supported themselves by plundering the country. At last one corps after another mutinied for their pay, and marched out of Transylvania; and Castaldo himself, unable to check the dissolution of his army, withdrew to Vienna. For a time anarchy prevailed in Transylvania; but in June, 1556, the inhabitants resolved to recall Isabella and her son. The envoys found her at Lemberg, and invited her to return. The Voivodes of Moldavia and Wallachia entered Hungary to protect her passage, and on October 22 she and her son entered Klausenburg in triumph.[289]
