As the Reich capital and military centre, Berlin was a major target of Allied air raids. For forced labourers, the air raids meant not only danger, but also the possibility of liberation.

At the beginning of September, 1943, Allied planes attacked the Berlin electrical industry. During the attack, a house at Grenzstraße 16 was hit, which housed female Polish forced labourers. The women worked as unskilled workers at the factory on Ackerstraße. 20 young Polish women were killed. It was not until 60 years later that they finally received gravestones and a memorial plaque.
