Agha Mohammad Khan crosses the Aras river in August 1795 with a seventy thousand-strong army.

This force is divided in three: the left wing is sent in the direction of Erivan, the right one parallel to the Caspian Sea into the Mughan across the lower Aras towards Dagestan and Shirvan, while the Shah heads the center force himself, advancing towards the fortress of Shusha in the Karabakh Khanate, which he besieges between July 8 and August 9, 1795.

His right and left wing force the Khans of Ganja and Erivan into alliance respectively.

Having abandoned the siege of Shusha due to stiff resistance, which is further aided by Georgian crown prince Aleksandre, the Khan of Karabakh, Ibrahim Khan, eventually surrenders to Mohammad Khan after discussions, including the paying of regular tribute and to surrender hostages, though the Qajar forces are still denied entrance to Shusha.

Since the main objective is Georgia, Mohammad Khan is willing to have Karabakh secured by this agreement for now, for he and his army subsequently move further.
