Vlora incident
The Vlora incident was a military attack by Albania against the Soviet Union in the Mediterranean Sea in 1961. It was a significant event in the history of Albania; it marked the culmination of political and military tensions between Albania and the Soviet Union, which led to the expulsion of Soviet forces from Albania. Background and prelude (1945–1961)
After World War II, Albania came under communist leadership, and under Enver Hoxha's direction, the country grew to be one of the Soviet Union's closest allies in Europe. The Albanian government received financial and military assistance from the Soviet Union, which also helped to industrialize the nation. However, in the 1960s, a rift developed between Albania and the Soviet Union as a result of divergent views on how to interpret Marxism-Leninism and the best method for implementing communism on a global scale. Albania criticised the USSR for being too accommodating towards the United States and its allies, and rejected the détente approach that the Soviet Union was pursuing with the West. In 1960, Enver Hoxha caused a rift with the Soviets after he aligned his military with China. Nikita Khrushchev hoped that Albania would serve as a military base on the Mediterranean Sea for "all the socialist countries" and provided equipment and training to the Albanian army, which included a fleet of twelve submarines. As a result of the rift the Soviet Union imposed economic sanctions on Albania, withdrew eight of the twelve submarines, broke up Soviet naval facilities at the Albanian port of Vlora, engaged in polemical exchanges with Albanian leadership and encouraged pro-Moscow leaders in Albania to stage a coup against Hoxha. Among the conspiracy's ringleaders was Vice Admiral Teme Sejko, a senior Albanian military officer. Although the submarines withdrawal came shortly after the announcement of a trial against Sejko, it should not be assumed that the Albanians had prompted the Soviets to withdraw. The Soviet position in the Mediterranean
During the Cold War, the Soviet Union tried to increase its military presence and influence outside of its boundaries, notably in the Mediterranean area. The stance of the Soviet Union in the Mediterranean was mainly intended to counter the United States and NATO, who maintained a sizable naval presence in the area. The Soviet Union was successful in increasing its naval presence in the Mediterranean. Albania was one instance of this, giving the Soviet Union a portion of its coastline as part of the latter's swift push into the Mediterranean. While comparatively insignificant politically and economically to the Soviet Union, Albania allowed the country to establish a strong military base that housed marines and larger units similar to destroyers. Vlora Base
Vlora Base, also known as Pasha Liman Base, was a major Soviet naval base on the Albanian coast. Established in 1957, it served as an important base for Soviet submarines and warships in the Mediterranean. The attack and withdrawal of the Soviet Navy

In 1961, the Albanian government decided to use military force to expel the Soviet forces from Albania and to take control of four of the twelve Soviet submarines. On April 7, 1961, Albanian troops began to position the Vlora base and encircle the Soviet soldiers. Soviet forces were ordered to evacuate the base and leave Albania. Soviet troops initially resisted, but after several days of siege and negotiations, an agreement was reached. Soviet forces left the Vlora base on April 12, 1961 and withdrew from Albania. The Soviets withdrew, recalling eight submarines. After the Soviets tried to leave Albania, they were pursued by the Albanian Naval Force and threatened with gunships. During this crisis, a group of Soviets were killed and a Soviet ship was destroyed by the Albanian army. Following these events, Khrushchev sought revenge on Albania. In 1962 he engaged with Warsaw Pact members on how they could launch an invasion of Albania. However, this plan was curtailed by the advent of the Cuban Missile Crisis. Aftermath
It led to the expulsion of the Soviets from Albania. During the attack several Soviet sailors were killed by Albanian Armed forces. After the incident, diplomatic relations between Albania and the Soviet Union were cut off and the Soviet Union lost access to the Mediterranean on the Albanian coast. See also
