Operation Tempest launched in Poland in 1944 would lead to several major actions by Armia Krajowa, most notable of them being the Warsaw Uprising that took place in between August 1 and October 2, and failed due to the Soviet refusal, due to differences in ideology, to help; another one was Operation Ostra Brama: the Armia Krajowa or Home Army turned the weapons given to them by the Nazi Germans (in hope that they would fight the incoming Soviets) against the nazi Germans—in the end the Home Army together with the Soviet troops took over the Greater Vilnius area to the dismay of the Lithuanians.
