The Polish government-in-exile in London was taken by surprise; it did not expect Ukrainian anti-Polish actions of such magnitude. There is no evidence that the Polish government-in-exile contemplated a general policy of revenge against the Ukrainians, but local Poles, including Home Army commanders, engaged in retaliatory actions. Polish partisans attacked the OUN, assassinated Ukrainian commanders, and carried out operations against Ukrainian villages. Retaliatory operations aimed at intimidating the Ukrainian population contributed to increased support for the UPA. The Home Army command tried to limit operations against Ukrainian civilians to a minimum. According to Grzegorz Motyka, the Polish operations resulted in 10,000 to 15,000 Ukrainian deaths in 1943–47, including 8,000-10,000 on territory of post-war Poland. From February to April 1945, mainly in "Rzeszowszczyzna" (the Rzeszów area), Polish units (including affiliates of the Home Army) carried out retaliatory attacks in which about 3,000 Ukrainians were killed; one of the most infamous ones is known as the Pawłokoma massacre.
