Establishment at Dargo
· Dargo, Chechnya, Caucasian Imamate (present-day Russia)

Wikimedia Commons · Public domain · file Following Akhulgo, Shamil established himself at Dargo in the Chechen forests, which became an important center of his resistance. The source establishes the move after the 1839 siege; 1840 is used because the related war chronology identifies that year as Shamil’s move into Chechnya.
