9 March 1949, Warsaw. A member of the District Commission for the Investigation of German Crimes, Judge Helena Wereńko, interviewed the person named below as an unsworn witness. Having been advised of the criminal liability for making false statements, the witness testified as follows:

| Parents’ names | Michał and Waleria, née Nowicka |

At both the outbreak of the war and that of the Warsaw Uprising I was in the house at Puławska Street 26 in Warsaw, where I worked as a stoker and janitor.
In 1940 (I don’t remember the exact date) the houses from Madalińskiego to Narbutta streets, including the house at Puławska Street 26, came to be occupied by the Germans, both soldiers and civilians. The house at Puławska Street 26 was inhabited by SS men whose headquarters were based at Aleje Ujazdowskie, in the buildings which had once housed the offices of the General Inspectorate of the Armed Forces. I don’t remember the name of the commander of the unit lodged in our house. I think he was called Pliuk. The house was managed by a man named Matoli, and one of the officers was called Dickman. At the moment when the Uprising started there were 10 SS men in the house. They were joined by about 20 more Germans who came from the city. In the morning of 1 August 1944, two trucks loaded with weapons and ammunition appeared at our house. The Germans put the load in the basements. At one point, when the Mokotów district was still fighting – I am unable to give the exact date – the insurgents launched an attack on our house from the direction of Narbutta Street. The attack was repulsed, and four or five wounded insurgents fell into German hands. Around 5 a.m. the insurgents were brought to the front of the garage in the courtyard. I saw them from the basement window. At about 10 a.m., officers Pliuk and Dickman arrived in a car, accompanied by a few soldiers. Looking through the window I could see the officers examine the wounded insurgents. One of the insurgents was saying something. The officers took him with them and drove away. When they left, the SS men (I don’t know their names) killed the rest. Their bodies were buried on Madalińskiego Street, in front of the Wedel house.
I also saw the SS man Reifert, an officer or non-commissioned officer, finish off a wounded woman in front of the house at Madalińskiego Street 2. She was a civilian who had come out into the street. At that time, there was no attack [from the insurgents].
A few days after the collapse of the Uprising, the Germans from our house left Warsaw and went in the direction of Kutno. I went to Piaseczno.
At this the report was concluded and read out.
