Nachtigall Battalion
Lviv was occupied by the Wehrmacht in the early hours of 30 June 1941; German forces consisted of the 1st Mountain Division and the Abwehr-subordinated Nachtigall Battalion staffed by ethnic Ukrainians. That day, Jews were press-ganged by the Germans to remove bodies of NKVD's victims from the prisons and to perform other tasks, such as clearing bomb damage and cleaning buildings. Some Jews were abused by the Germans and even murdered, according to survivors. During the afternoon of the same day, the German military reported that the Lviv population was taking out its anger about the prison murders "on the Jews ... who had always collaborated with the Bolsheviks".
