In 591, Khosrow moved to [[Viranşehir|Constantia]] and prepared to invade Bahram Chobin's territories in Mesopotamia, while Vistahm and Vinduyih were raising an army in [[Adurbadagan]] under the observation of the Byzantine commander [[John Mystacon]], who was also raising an army in Armenia. After some time, Khosrow, along with the Byzantine commander of the south, [[Comentiolus]], invaded Mesopotamia. During this invasion, [[Nisibis]] and Martyropolis quickly defected to them,{{sfn|Howard-Johnston|2010}} and Bahram Chobin's commander Zatsparham was defeated and killed.{{sfn|Greatrex|Lieu|2002|p=173}} One of Bahram Chobin's other commanders, Bryzacius, was captured in [[Mosul|Mosil]] and had his nose and ears cut off, and was thereafter sent to Khosrow, where he was killed.{{sfn|Martindale|Jones|Morris|1992|p=251}}{{sfn|Rawlinson|2004|p=509}} Khosrow II and the Byzantine general [[Narses (magister militum per Orientem)|Narses]] then penetrated deeper into Bahram's territory, seizing Dara and then [[Mardin]] in February, where Khosrow was re-proclaimed king.{{sfn|Greatrex|Lieu|2002|p=173}} Shortly after this, Khosrow sent one of his Iranian supporters, Mahbodh, to capture Ctesiphon, which he managed to accomplish.{{sfn|Greatrex|Lieu|2002|p=174}}

At the same time a force of 8,000 Iranians under Vistahm and Vinduyih and 12,000 Armenians under [[Mushegh II Mamikonian]] invaded Adurbadagan.{{sfn|Shahbazi|1988|pp=514–522}} Bahram Chobin tried to disrupt the force by writing a letter to Mushegh II, the letter said: "As for you Armenians who demonstrate an unseasonable loyalty, did not the house of Sasan destroy your land and sovereignty? Why otherwise did your fathers rebel and extricate themselves from their service, fighting up until today for your country?"{{sfn|Pourshariati|2008|pp=128–129}} Bahram Chobin in his letter promised that the Armenians would become partners of the new Iranian empire ruled by a Parthian dynastic family if he accepted his proposal to betray Khosrow II.{{sfn|Pourshariati|2008|p=129}} Mushegh, however, rejected the offer.{{sfn|Pourshariati|2008|p=129}}

Bahram Chobin was then defeated at the [[Battle of Blarathon]], forcing him to flee with 4,000 men eastwards. He marched towards [[Nishapur]], where he defeated a pursuing army as well as an army led by a [[House of Karen|Karenid]] nobleman at [[Qumis (region)|Qumis]]. Constantly troubled, he crossed the [[Oxus river]], where he was received honorably by the Khagan of the Turks, who was most likely Birmudha—the same Turkic prince that Bahram Chobin had defeated and captured a few years earlier during his wars against the Turks.{{sfn|Shahbazi|1988|pp=514–522}}{{sfn|Rezakhani|2017|p=178}} Bahram Chobin entered his service, and was appointed as a commander in the army, achieving further military accomplishments there.{{sfn|Shahbazi|1988|pp=514–522}}{{sfn|Kia|2016|p=242}} Bahram Chobin became a highly popular figure after saving the Khagan from a conspiracy instigated by the latter's brother Byghu (conceivably an incorrect translation of ''[[yabghu]]'').{{sfn|Rezakhani|2017|p=178}} Khosrow II, however, could not feel safe as long as Bahram Chobin lived, and succeeded in having him assassinated.{{sfn|Shahbazi|1988|pp=514–522}} The assassination was reportedly achieved through distribution of presents and bribes between the members of the Turkic royal family, notably the queen.{{sfn|Kia|2016|p=242}} What remained of Bahram Chobin's supporters went back to northern Iran and joined the [[rebellion of Vistahm]] (590/1–596 or 594/5–600).{{sfn|Pourshariati|2008|pp=133–134}}
