The resulting territorial loss of 188,000 km² (formerly populated by 5.3 million ethnic Poles[5]) was to be compensated by the addition of 111,000 km² of former German territory east of the Oder–Neisse line (formerly populated by 11.4 million ethnic Germans[6]). Kidnapping of Polish children by Germany also took place, in which children who were believed to hold German blood were taken away; 20,000–200,000[7] Polish children were taken away from their parents. Out of the abducted only 10–15% returned home.[8] Polish elites were decimated and over half of the Polish intelligentsia were murdered.
