The deportation of the Chechens and Ingush (Chechen: До́хадар, Махках дахар, romanized: Doxadar, Maxkax daxar, Ingush: Мехках дахар) also known as Operation Lentil (Russian: Чечевица, romanized: Chechevitsa; Chechen: нохчий а, гӀалгӀай а махкахбахар, romanized: noxçiy ə, ġalġay ə maxkaxbaxar) and the Aardakh genocide, was the Soviet forced transfer of the whole of the Vainakh (Chechen and Ingush) populations of the North Caucasus to Central Asia on 23 February 1944, during World War II. The expulsion was ordered by NKVD chief Lavrentiy Beria after approval by Soviet leader and dictator Joseph Stalin as part of a Soviet forced settlement program and population transfer that affected several million members of ethnic minorities in the Soviet Union between the 1930s and the 1950s.
The deportation was prepared from at least October 1943 and 19,000 officers as well as 100,000 NKVD soldiers from all over the USSR participated in this operation. The deportation encompassed their entire nations, as well as the liquidation of the Checheno-Ingush Autonomous Soviet Socialist Republic. The demographic consequences of this eviction were catastrophic and far-reaching: of the 496,000 Chechens and Ingush who were deported, at least a quarter died. In total, the archive records show that over a hundred thousand people died or were killed during the round-ups and transportation, and during their early years in exile in the Kazakh and Kyrgyz SSR, as well as Russian SFSR where they were sent to the many forced settlements. Chechen sources claim that 400,000 died, while presuming a higher number of deportees. A higher percentage of Chechens were killed than any other ethnic group persecuted by population transfer in the Soviet Union. Chechens were under administrative supervision of the NKVD officials during that entire time.
