The Karabakh Khanate submit to the Russians…
May 1805 CE
In response to the loss of Karabakh, Abbas Mirza occupies the Askeran Fortress at the mouth of a valley that leads from the plain southwest to Shusha, the capital of Karabakh.
The Russians respond by sending Koryagin to take the Persian fort of Shakh-Bulakh.
Abbas Mirza marches north and besieges the place.
On hearing of the approach of another army under Fath Ali, Koryagin slips out at night and heads for Shusha.
He is caught at the Askeran gorge but not defeated, and additional Russian troops relieve the blockade of Koryagin and Shusha.
