in the campaign “Forcing Chechnya into submission after the fall of Akhulgo and suppression of the general uprising of 1840 (1838-1840)”
The empire answered the Chechen uprising by sending in troops. General Pullo, who commanded the left flank of the Caucasus Line (the chain of imperial fortifications on the land of the Nokhchi), reported on 9 March 1840 about marching out against the insurgents: "I set out yesterday for Khankala with 5 companies" (Khankala - a tract by the Groznaya fortress)[1]. The second deployment was a detachment on the Sunzha river: an imperial instruction of 25 March 1840 set it the task of "keeping the Karabulaks in submission" (the Karabulaks - a Vainakh community between Chechnya and Ingushetia; "submission" - the empire's formula of subordination)[1].
