Surprise Abbasid attack

On 23 February 811, a small army from the rebellion in Tashkent was attacked by Abbasid forces just outside Samarqand, commanded by the Abbasid general Abu Kariz al-Salain. Some 1, 200 soldiers from Tashkent were killed, but only 250 Abbasid soldiers died in the battlefield near Samarqand. As a result of this, the main rebellion was delayed, and Makhmud al-Ibrahim, the commander from Tashkent, was replaced by general Tarkun Ayarbakh.
