Unsuccessful assaults and supply issues led to the Ottomans lifting the siege in July 1626 and retreating to Mosul, resulting in a strategic Persian victory.

Subsequently, the Persians, under Shah Abbas, swiftly capitalized on the Ottoman weakness, capturing most of Iraq, including key cities such as Kirkuk and Mosul.

[1] In November 1625, Hafız Ahmed Pasha's Ottoman forces reached Baghdad, investing the city from three sides despite a "scorched earth" policy implemented by the Shah to hinder their advance.

The Ottomans managed to breach the outer fortifications of Baghdad but failed to capture the city before the arrival of a relief army under Shah Abbas.

As a result, on July 4, 1626, the Ottoman army lifted the siege of Baghdad and withdrew to Mosul, marking a strategic victory for Shah Abbas and the Persian forces.
