Nachtigall Battalion
Four days before the attack on the Soviet Union, the Battalion was moved to the border. On the night of June 23–24, 1941, the Battalion crossed the border near Przemyśl while traveling in the direction of Lviv. The Nachtigall Battalion traveled along with a Panzer-Jaeger Division and some tank units went along through Radymno-Lviv-Ternopil-Proskuriv-Vinnytsia path. As part of the 1st Brandenburg Battalion, the first soldiers of the Nachtigall Battalion entered Lviv on June 29. The battalion took up guard of strategic objects, the most important of which was the radio station on the Vysoky Zamok Hill in the centre of Lviv. From the radio station, the proclamation of the Act of Ukrainian Independence was made.
