The Operation B was a name for Czechoslovak military operation aimed against members of Ukrainian Insurgent Army who entered Czechoslovak territory. [1]
UPA was tasked with conducting raids into Czechoslovak territory. In particular, the goal was to analyze internal political situation of Czechoslovakia. UPA leadership believed that "Bolshevization" of Czechoslovakia was proceeding more slowly than in other Eastern states, so it was the best place to spread OUN propaganda. [8] In September 1945, UPA fighters tasked with the raids were given training, in particular "to strengthen political education work in the departments raiding foreign lands". [9] On 8 August, 1945, insurgents completed their final preparations for the raid. [10] Czechoslovak authorities responded with Operation "B" when UPA incursions into Czechoslovakia begun.
First members of Ukrainian Insurgent Army entered Czechoslovakia on 13 August, 1945, near the villages of Spišská Stará Ves and Medzilaborce. There were reports of other groups attacking robbing villages near border with Poland. Czechoslovakia sent more units to the area that pushed Ukrainian insurgents back to Poland. [11] Czechoslovak units were commanded by Colonel Jan Heřman. [1]
Polish army launched offensive against Ukrainian Insurgent Army in January 1946. Czechoslovakia reacted by sending more units near borders expecting more insurgents trying to enter Czechoslovakia. [12] Ukrainian Insurgent Army became more active near Polish border with Slovakia and more units entered Czechoslovak territory there. In April 1946 units led by Colonel Heřman launched offensive against insurgents pushing them back to Poland. During late 1946, situation in Slovakia became calmer. [5]
During early 1947, insurgents led some raids to Czechoslovak territory and during summer 1947 launched their largest attack to Czechoslovakia trying to reach western Europe through its territory. Some groups even entered Moravia and South Bohemia. [12] The bloodiest clash occurred on 5 August, 1947, at Partizánská Ľupča which resulted in death of 6 members of Czechoslovak security forces. Czechoslovak units were gradually destroying Ukrainian insurgents, and fights concluded on 17 November, 1947, when the last forces of the Ukrainian Insurgent Army were pushed out. [7] Members of OUN captured 33 villages in Czechoslovakia. [7] Some small units continued crossing even after 1947.
The 1947 raid ended with most UPA members being killed or captured, and only about 60 managing to enter German territory. However, some UPA units continued crossing after 1947, when the operation was no longer on such a large scale. As a result, over 200 more members entered Germany in 1948, bringing the total number of UPA members who made it into Germany to over 300. [5]
