Abu Sa'id Mirza, on receiving intelligence of his rivals’ advance, sets out to meet this threat head on despite being numerically outnumbered, and sends for reinforcements.

The vanguard of Ala-ud-Daulah Mirza bin Baysonqor, Ibrahim Mirza bin Ala-ud-Daulah and Sultan Sanjar Mirza appears between Marv and Sarakhs in March 1459.

Battle lines are drawn and a pitched battle ensues.

Reinforcements arrive for Abu Sa'id Mirza at the right time under Amir Ali Farsi and Amir Syed Asil, and with their help he defeats his enemies.

Amir Ali Farsi and Amir Syed Asil are sent in pursuit of Ala-ud-Daulah Mirza bin Baysonqor and Ibrahim Mirza bin Ala-ud-Daulah, who had fled to Mazniyan; Sultan Sanjar Mirza is captured and is executed.

Ibrahim dies only a few months later; his father will die the following year.
