Géczi sent letters to András Nagy (who promised to murder Gabriel), but Nagy's letter was captured. Gabriel killed Nagy or had him executed in August, according to various sources. Gabriel Bethlen (the leading figure of the pro-Ottoman policy) fled to Ottoman territory on 12 September, and visited the Ottoman governors of Temesvár, Buda and Kanizsa. With their help, he contacted the grand vizier Nasuh Pasha. Weiss, who wanted to install Géczi as prince in Gyulafehérvár, left Brassó at the head of an undisciplined army on 8 October 1612. Gabriel attacked Weiss and his troops, annihilating them six days later. Weiss was beheaded on the battlefield, and Géczi withdrew to Brassó. The Diet sentenced the absent Géczi and Bethlen to death, granting amnesty to those who had surrendered.
