An estimated 60,000 Lithuanians were drafted into the Red Army. During 1940, on the basis of disbanded Lithuanian Army, Soviet authorities organized 29th Territorial Rifle Corps. Decrease in quality of life and service conditions, forceful indoctrination of Communist ideology, caused discontent of recently Sovietized military units. Soviet authorities responded with repressions against Lithuanian officers of the 29th Corps, arresting over 100 officers and soldiers and subsequently executing around 20 in Autumn 1940. By that time allegedly near 3,200 officers and soldiers of 29th Corps were considered "politically unreliable". Due to high tensions and soldiers' discontent the 26th Cavalry Regiment was disbanded. During the 1941 June deportations over 320 officers and soldiers of 29th Corps were arrested and deported to concentration camps or executed. The 29th Corps collapsed with the German invasion into Soviet Union: on June 25–26 a rebellion broke in its 184th Rifle Division. The other division of the 29th Corps, the 179th Rifle Division lost most of its soldiers during the retreat from Germans mostly to deserting of its soldiers. A total of less than 1,500 soldiers from initial strength of around 12,000 reached the area of Pskov by August 1941. By the second part of 1942, most of Lithuanians remaining in the Soviet ranks as well as male war refugees from Lithuania were organized into 16th Rifle Division during its second formation. 16th Rifle Division, despite officially called "Lithuanian" and mostly commanded by officers of Lithuanian origin, including Adolfas Urbšas, was ethnically very mixed, with up to 1/4 of its personnel made of Jews and thus being the largest Jew formation of Soviet Army. Popular joke of those years said that 16th Division is called Lithuanian, because there are 16 Lithuanians among its ranks.
