İshak escaped to Silifke, the southern frontier of the beylik and Pir Ahmet assumed the title bey.
However, Mehmet returned and captured both Karaman (Larende) and Konya two major cities of the beylik in 1468.
(This was the reason behind the Battle of Otlukbeli in 1473) With Akkoyunlu support, Pir Ahmet captured Karaman.
Because immediately after the capture of Karaman, Akkoyunlu army was defeated by the Ottomans near Beyşehir and Pir Ahmet had to escape once more.
Although he tried to continue his struggle, he learned that his family members were transferred to Istanbul by Gedik Ahmet Pasha and he finally gave up.
