Rapid reversals at the front changed the course of the battle; after the encirclement of the German forces in Stalingrad, the subsequent Soviet offensive that began on 16 December 1942 overwhelmed the 2nd and 35th Italian Army Corps (former CSIR), which were part of the southern deployment of the 8th Army, and six Italian divisions together with German and Romanian forces were forced to a hasty retreat. On 13 January 1943, a second major Soviet offensive north of the Don overwhelmed the Alpini troops still in line, poorly equipped and short of supplies, which began a retreat in the steppe, pursued by Soviet divisions, and were forced to suffer enormous misery. The retreat cost the Italian forces tens of thousands of losses and ended on 31 January, when the 2nd Alpine Division Tridentina reached the first German outposts in Shebekino. The repatriating operations lasted from 6 to 15 March and ended on 24 March, putting an end to the Italian military operations in the Soviet Union.
