On 22 July 1944, Soviet troops reached the Polish city of Lublin. Here, they discovered the Majdanek labour and extermination camp, which was situated close to the city. The guards had already left.
The Nazis had tried to erase their traces. Barracks had been demolished, bodies of murdered people had been burned, and the camp archives had been destroyed. But many barracks were still standing, and the gas chambers and some crematoria were still intact. Many prisoners had been left behind.
