northern Bukovina with the help of Wehrmacht. The Soviets employed scorched earth tactics during their forced retreat from Bessarabia, destroying the infrastructure and transporting movable goods to Russia by railway. At the end of July, after a year of Soviet rule, the region was once again under Romanian control, being organized as the Bessarabia Governorate. As the military operation was still in progress, there were cases of Romanian troops "taking revenge" on Jews in Bessarabia, in the form of pogroms on civilians and murder of Jewish POWs, resulting in several thousand dead. The supposed cause for murdering Jews was that in 1940 some Jews welcomed the Soviet takeover as liberation. At the same time the notorious SS Einsatzgruppe D, operating in the area of the German 11th Army, committed summary executions of Jews under the pretext that they were spies, saboteurs, Communists, or under no pretext whatsoever. The political solution of the "Jewish Question" was apparently seen by the Romanian dictator Marshal Ion Antonescu more in expulsion rather than extermination. That portion of the Jewish population of Bessarabia and Bukovina which did not flee before the retreat of the Soviet troops (147,000) was initially gathered into ghettos or Nazi concentration camps, and then deported during 1941–1942 in death marches into Romanian-occupied Transnistria, where the "Final Solution" was applied. After three years of relative peace, the German-Soviet front returned in 1944 to the land border on the Dniester. On August 20, 1944, a c. 3,400,000-strong Red Army began a major summer offensive codenamed Second Jassy–Kishinev offensive. The Soviet armies overran Bessarabia in a two-pronged offensive within five days. In pocket battles at Chișinău and Sărata the German 6th Army of 650,000 men, newly reformed after the Battle of Stalingrad, was obliterated. Simultaneously with the success of the Russian attack, Romania broke the military alliance with the Axis and changed sides. On August 23, 1944, Marshal Ion Antonescu was arrested by King Michael, and later handed over to the Soviets. Part of the Soviet Union The Soviet Union regained the region in 1944, and the Red Army occupied Romania. By 1947, the Soviets had imposed a communist government in Bucharest, which was friendly and obedient towards Moscow. The Soviet occupation of Romania lasted until 1958. The Romanian communist regime did not openly raise the matter of Bessarabia or Northern Bukovina in its diplomatic relations with the Soviet Union. At least 100,000 people
