This article studies the reaction of the Baltic press and political journalism to the introduction of additional troops of the Red Army in Estonia, Latvia and in Lithuania in June 1940. The relationship between the USSR and the Baltic States before and during the introduction of additional troops in the territory of the Baltic States is illustrated on the example of publications and press reviews of the Soviet embassies in Estonia, Latvia and in Lithuania kept in the «Russian State Foreign Policy Archive». The author‘s research objective was an attempt through the study of the archival materials to show the mass media reaction to the introduction of Soviet troops in the Baltic states. Besides, the author points out in his paper that the press and journalism of Lithuania, Estonia and Latvia were censored, and that contributed to the official media positive assessment of the USSR policy. The research backs the idea that despite the attitude of Soviet soldiers of the Red Army to Estonians, Latvians and Lithuanians as potential enemies the citizens of the Baltic States and soldiers of the Red Army were amenable to compromise.
