Vilnius Region
The mission of the LTDF was to defend the country against the approaching Soviet Red Army. Since the Red Army had not entered the Lithuanian lands to which LTDF was confined, the force was used instead to aid the Nazis in their operations against Soviet and Polish partisans operating in the Lithuanian territory. In April, the Polish Armia Krajowa (AK) in the Vilnius Region attempted to begin negotiations with Plechavičius, proposing a non-aggression pact and cooperation against the Nazi Germany. The Lithuanian side refused and demanded that the Poles either abandon the Vilnius Region (disputed between Poles and Lithuanians) or subordinate themselves to the Lithuanians in their struggle against the Soviets.
