A Tatarian brigade headed from Samarkand towards Taloqan, North-East of Afghanistan, near Tajikistan, but it was difficult for them to conquer it, due to its impregnable forts.

They sent a message to Genghis Khan, who came by himself and besieged the city for some months before he conquered it, killed its men, captured its women and children, and robbed its wealth and possessions, as was the habit of the Tatars.
