"A transport had arrived from Holland and the prisoners had to jump from the wagons. They were well-off Jews. There were women with Persian furs. They arrived by express train. The trucks were already there, with wooden steps before them, and the people climbed aboard. Then they all started off. In the place Birkenau once stood, there was only a long farmhouse (Bunker 2) and beside it four or five big huts. Inside, the people were standing on clothes which were building up on the floor. The block leader and the sergeant, carrying a cane, were there. Hoeblinger said to me 'lets go over there now'. There was a sign 'to disinfection'. He said 'you see, they are bringing children now'. They opened the door, threw the children in and closed the door. There was a terrible cry. A member of the SS climbed on the roof. The people went on crying for about ten minutes. Then the prisoners opened the doors. Everything was in disorder and contorted. Heat was given off. The bodies were loaded on a rough wagon and taken to a ditch. The next batch were already undressing in the huts. After that I didn't look at my wife for four weeks."
