Soviet partisans
In eastern and south-eastern Lithuania, Soviet partisans constantly clashed with Polish [[Armia Krajowa]] ("Home Army") partisans; AK did not recognise any territorial changes after 1939 and considered this region as a legal part of Poland, while the Soviets planned to annex it into the Soviet Union after the war. Only in April 1944 did Polish and Soviet partisans start coordinating their actions against the Germans.
