I'm sure Russian casualties were non-trivial, but it's not like the Russians were keeping count and broadcasting them. Still, the atrocities carried out against the Chechens make Beslan look like trivial:
It was initiated on October 13, 1943, when about 120,000 men were moved into Checheno-Ingushetia, supposedly for mending bridges. On February 23, 1944 (on Red Army Day), the entire population was summoned to local Party buildings where they were told they were going to be deported as punishment for their alleged collaboration with the Germans. The inhabitants were rounded up and imprisoned in Studebaker trucks manufactured in and supplied by the United States, before being packed into unheated and uninsulated freight cars.[13][14] Some 40% to 50% of the deportees were children.[15]
Many times, resistance was met with slaughter, and in one such instance, in the aul of Khaibakh, about 700 people were locked in a barn and burned to death by NKVD General Mikheil Gveshiani, who was praised for this and promised a medal by Beria. Many people from remote villages were executed per Beria's verbal order that any Chechen or Ingush deemed 'untransportable should be liquidated' on the spot.[16] An eyewitness recalled the actions of the NKVD forces:[17]
A lot more Russians would have to die at Chechen hands to even up the score.
They combed the huts to make sure there was no one left behind... The soldier who came into the house did not want to bend down. He raked the hut with a burst from his submachine gun. Blood trickled out from under the bench where a child was hiding. The mother screamed and hurled herself at the soldier. He shot her too. There was not enough rolling stock. Those left behind were shot. The bodies were covered with earth and sand, carelessly. The shooting had also been careless, and people started wriggling out of the sand like worms. The NKVD men spent the whole night shooting them all over again. Throughout the North Caucasus, about 700,000 (according to Dalkhat Ediev, 724,297,[18] of which the majority, 479,478, were Chechens, along with 96,327 Ingush, 104,146 Kalmyks, 39,407 Balkars and 71,869 Karachays). Many died en route, and the extremely harsh environment of exile (especially considering the amount of exposure) killed many more. The NKVD, supplying the Russian perspective, gives the statistic of 144,704 people killed in 1944-1948 alone (death rate of 23.5% per all groups), though this is dismissed by many authors such as Tony Wood, John Dunlop, Moshe Gammer and others as a significant understatement.[19] Estimates for deaths of the Chechens alone (excluding the NKVD figures), range from about 170,000 to 200,000,[20][21][22][23] thus ranging from over a third of the total Chechen population to nearly half being killed in those 4 years alone (rates for other groups for those four years hover around 20%). Certain modern Russian sources, however, dispute that there were deliberately harsh conditions set for Chechens as opposed to other nationalities, and point to population growth in the 1959 census.[24]
