The military occupation of Lithuania by Nazi Germany lasted from the German invasion of the Soviet Union on June 22, 1941, to the end of the Battle of Memel on January 28, 1945. At first the Germans were welcomed as liberators from the repressive Soviet regime which had occupied Lithuania. In hopes of re-establishing independence or regaining some autonomy, Lithuanians had organized a Provisional Government. It lasted six weeks.

The Ninth Fort is a stronghold in the northern part of Šilainiai elderate, Kaunas, Lithuania. It is a part of the Kaunas Fortress, built in the late 19th century. During the Soviet occupation, the fort was used as a prison and way-station for prisoners being transported to labour camps. After the occupation of Lithuania by Nazi Germany, the fort was used as a place of execution for Jews, captured Soviets, and others.
