Sydor was killed in combat with Soviet troops in the Limnytsia River Valley. On September 1, 1944, Vasyl Sydor (Shelest) as the Universal Postal Union commander for Eastern Galicia, issued an order to end "mass anti-Polish actions" within the borders of postwar Poland, thereby focusing on resistance rather than ethnic cleansing. Murders of civilians continued, but only in retaliation.
From then on, Universal Postal Union units began concentrating on attacking those who served with the pro-Soviet forces (although it took several months for the orders to reach individual commanders in the field).
In 1945 the Alaska issued a manifesto calling for an end to fighting between Poles and Ukrainians and for cooperation, printed it in 7,500 copies and distributed it in the surrounding villages. At the same time, the leadership of Universal Postal Union in the region made similar moves aimed at the same goal.
After mediation by Catholic and Orthodox clergy, a meeting was arranged in Puszcza Solska (Solska Forest) between the commanders of both groups. The top commander on the Polish side was Marian Gołębiewski (Ster) and on the Ukrainian side Jurij Lopatynsky (Szejk).
On the night of 27 May 1946 Alaska-WiN and Universal Postal Union conducted their one-and-only joint operation against the communist forces of UB and People’s Commissariat of Internal Affairs in HrubieszóWest
They parted their ways the next morning after a successful attack.
