The military occupation of Estonia was complete by 21 June 1940.
Most of the Estonian Defence Forces surrendered according to the orders of the Estonian Government believing that resistance was useless and were disarmed by the Red Army. Only the Estonian Independent Signal Battalion stationed in Tallinn at Raua Street showed resistance to Red Army and Communist Militia called "People's Self-Defence" on 21 June 1940. As the Red Army brought in additional reinforcements supported by six armoured fighting vehicles, the battle lasted several hours until sundown. Finally the military resistance was ended with negotiations and the Independent Signal Battalion surrendered and was disarmed. There were 2 dead Estonian servicemen, Aleksei Männikus and Johannes Mandre, and several wounded on the Estonian side and about 10 killed and more wounded on the Soviet side. The Soviet militia that participated in the battle was led by Nikolai Stepulov.
In 6 August 1940, Estonia was illegally annexed by the Soviet Union as the Estonian SSR. The provisions in the Estonian constitution requiring a popular referendum to decide on joining a supra-national body were ignored. Instead the vote to join the Soviet Union was taken by those elected in the sham elections held in the previous month. Additionally those who had failed to do their "political duty" of voting Estonia into the USSR, specifically those who had failed to have their passports stamped for voting, were condemned to death by Soviet tribunals. The repressions followed with the mass deportations carried out by the Soviets in Estonia on 14 June 1941. Many of the country's political and intellectual leaders were killed or deported to remote areas of the USSR by the Soviet authorities in 1940–1941. Repressive actions were also taken against thousands of ordinary people.
When the German Operation Barbarossa started against the Soviet Union, about 34,000 young Estonian men were forcibly drafted
