Transylvania for Buda in October. Vlad bought a house in Pécs that became known as Drakula háza ("Dracula's house" in Hungarian). In January 1476 John Pongrác of Dengeleg, Voivode of Transylvania urged the people of Brașov to send to Vlad all those of his supporters who had settled in the town, because Corvinus and Basarab Laiotă had concluded a treaty. The relationship between the Transylvanian Saxons and Basarab remained tense, and the Saxons gave shelter to Basarab's opponents during the following months. Corvinus dispatched Vlad and the Serbian Vuk Grgurević to fight against the Ottomans in Bosnia in early 1476. They captured Srebrenica and other fortresses in February and March 1476. In the Bosnian campaign, Vlad once again resorted to his terror tactics, mass impaling captured Turkish soldiers and massacring civilians in conquered settlements. His troops mostly destroyed Srebrenica, Kuslat, and Zvornik. Mehmed II invaded Moldavia and defeated StephenIII in the Battle of Valea Albă on 26July 1476. Stephen Báthory and Vlad entered Moldavia, forcing the sultan to lift the siege of the fortress at Târgu Neamț in late August, according to a letter of Matthias Corvinus. The contemporaneous Jakob Unrest added that Vuk Grgurević and a member of the noble Jakšić family also participated in the struggle against the Ottomans in Moldavia. Matthias Corvinus ordered the Transylvanian Saxons to support Báthory's planned invasion of Wallachia on 6September 1476, also informing them that Stephen of Moldavia would also invade Wallachia. Vlad stayed in Brașov and confirmed the commercial privileges of the local burghers in Wallachia on 7October 1476. Báthory's forces captured Târgoviște on 8November. Stephen of Moldavia and Vlad ceremoniously confirmed their alliance, and they occupied Bucharest, forcing Basarab Laiotă to seek refuge in the Ottoman Empire on 16November. Vlad informed the merchants of Brașov about his victory, urging them to come to Wallachia. He was crowned before 26November. Basarab Laiotă returned to Wallachia with Ottoman support, and Vlad died fighting against them in late December 1476 or early January 1477. In a letter written on 10January 1477, StephenIII of Moldavia related that Vlad's Moldavian retinue had also been massacred. According to the "most reliable sources", Vlad's army of about 2,000 was cornered and destroyed by a Turkish-Basarab force of 4,000 near Snagov. The exact circumstances of his death are unclear. The Austrian chronicler Jacob Unrest stated that a disguised Turkish assassin murdered Vlad in his camp. In contrast, Russian
