in the campaign “Forcing Chechnya into submission after the fall of Akhulgo and suppression of the general uprising of 1840 (1838-1840)”
The winter expeditions of general Pullo, who commanded the left flank of the Caucasus Line (the chain of imperial fortifications on the land of the Nokhchi), collected money from the Chechen auls under the name of tribute. The imperial historian Yurov tallied the December 1839 march: "In all, during this bloodless military promenade, 3779 rubles and 455 rifles were collected, and 97 abreks, 7 captives and two fugitives were handed over" (abrek - the empire's label for an outlawed highlander)[1], and the January 1840 march along the Michik river: the auls "obediently presented 2463 rubles, 545 rifles, cattle for the detachment's provisioning, and handed over 30 abreks"[1]. After the suppression of the uprising the levy was fixed as a fine: point 10 of the "Conditions prescribed to submitting highlanders", issued by general Grabbe, commander of the troops of the Caucasus Line, on 15 June 1840, prescribed "As punishment for participation in Shamil's uprising, to pay a fine of two rams from every saklia" (saklia - a highlander's house; Shamil - the imam, leader of the resistance of the highlanders of Dagestan and Chechnya to the Russian conquest)[2].
