In February-April 1837, continuing the January annihilation of Lesser Chechnya (campaign C1160), the command of the Russian Caucasus Corps conducted a series of expeditions under General Feze across eastern and central Chechnya: the February movement through Shali, Germenchuk and the Michik, the March march up the Dzhalka, and the April night raid on the Gertli settlement. Rozen set out the sanction in a dispatch to Minister of War Chernyshev: a campaign "beyond the Argun" - "for diminishing the Chechens' trust in the instigators and turning them away from the intention of joining Shamil" (Shamil - imam, leader of the Dagestani and Chechen highlanders' resistance to the Russian conquest)[1]. The Gertli raid was declared a punishment in Rozen's report to Chernyshev of 30 May 1837: "for the devastation or final annihilation of this brigand party... and for the punishment of its inhabitants"[1].
