The armies of Hormizd under Farrukhan faced the army of Bahram Chobin across the River Zab. Neither wanted to be the first to try crossing the river and putting themselves into a vulnerable position. Farrukhan might also have delayed in hopes that the rebellion would dissolve over time.
Unfortunately, Zadspram deserted Farrukhan. This desertion demoralized the army. Two of Farrukhan's officers killed Farrakhan, and the loyalist army fell apart.
Meanwhile, Hormizd was in Ctesiphon, the Iranian royal capital for over 800 years. Enter Vistahm and Vinduyih. They were Hormizd's brothers-in-law, and they hated him. They decided to get Hormizd off the throne, so they blinded him with a red-hot needle in 590. The brothers elevated his son, their nephew Khosrow II (born c.570), to the position of emperor. Not long after, the two dealt with Hormizd permanently by strangling him with his own turban.
Accounts written later disagree on whether Khosrow II was involved in the murder of his father. A few years after the event, Khosrow executed both uncles for the murder of his father, along with others he considered co-conspirators.
With the news of the death of Hormizd, Bahram Chobin continued his march to the capital under the public pretext of avenging the assassination of the emperor. Now, however, he was Khosrow II's problem. Whether this would make Khosrow II's reign a short one will be picked up tomorrow.
