The massacre of the hamlet of naib Duba (a deputy of Imam Shamil, leader of the highlanders' resistance to the Russian conquest) on 6 March 1847 was prepared by a targeted bribe inside the naib's family. Imperial officer Poltoratsky, a participant in the assault, wrote of the detachment's guide: "This was naib Duba's own nephew, bribed together with his brother for a good cut out of the pocket of Meller" - Meller-Zakomelsky, who commanded the detachment[1]. Both brothers were bought: one led the troops against his native hamlet, the other sat as a hostage in Vozdvizhenskoye - a guarantee that the guide would not change his mind.
