of the country. On 28 October 1939, the Red Army withdrew from the city to its suburbs (to Naujoji Vilnia) and Vilnius was given over to Lithuania. A Lithuanian Army parade took place on 29 October 1939 through the city center. The Lithuanians immediately attempted to re-Lithuanize the city, for example by Lithuanizing Polish schools. Following the normalisation of relation with Poland the Lithuanian Consulate was opened in Vilnius on 22 August 1939, but the consul started operating there only after the war already began, on 9 September 1939. The whole of Lithuania was annexed by the Soviet Union on 3 August 1940 following a June ultimatum from the Soviets demanding, among other things, that unspecified numbers of Red Army soldiers be allowed to enter the country for the purpose of helping to form a more pro-Soviet government. After the ultimatum was issued and Lithuania further occupied, a Soviet government was installed with Vilnius as the capital of the newly created Lithuanian SSR. Between 20,000 and 30,000 of the city's inhabitants were subsequently arrested by the NKVD and sent to gulags in the far eastern areas of the Soviet Union. On 22 June 1941, the Germans launched Operation Barbarossa against the Soviet Union, while at the same time Lithuanians began the anti-Soviet June Uprising, organized by the Lithuanian Activist Front. Lithuanians proclaimed independence and organized the Provisional Government of Lithuania. This government quickly self-disbanded. Nazis captured Vilnius on 24 June 1941. Lithuania became part of the Reichskommissariat Ostland, German civil administration. Two ghettos were set up in the old town centre for the large Jewish population – the smaller one of which was "liquidated" by October. The larger ghetto lasted until 1943, though its population was regularly deported in roundups known as "Aktionen". A forced labour camp (Kailis) was also set up behind the Vilnius Town Hall as a factory to produce winter clothing for the Wehrmacht and another one later for vehicle repair (HKP 562) on 47 & 49 Subačiaus Street. A failed ghetto uprising on 1 September 1943 organized by the Fareinigte Partizaner Organizacje (the United Partisan Organization, the first Jewish partisan unit in German-occupied Europe), was followed by the final destruction of the ghetto. During the Holocaust, about 95% of the 265,000-strong Jewish population of Lithuania was murdered by the German units and Lithuanian Nazi collaborators, many of them in Paneriai, about west of the old town
