During the Warsaw Uprising I worked as a concierge in the house at Racławicka Street 126. Prior to the war, the house had been home to the First Lady, Maria Mościcka. In 1940, the Germans set up a casino in her apartments, taking advantage of the old furniture and adding some new appliances. Shortly before the outbreak of the Uprising, the general (I don’t know his name), who was in charge of the airfield and the Mokotów fort, moved into the apartment on the first floor. Around 15 August 1944, after two weeks of staying in this apartment, he went, as I heard from the soldiers, to Kutno.
I saw German soldiers load trucks with various things from the former First Lady’s apartment. I know for certain that they took two wooden beds and carpets.
I didn’t notice what else they took. Because the apartment had been used for several years, the things were quite worn. I also saw German soldiers load trucks with some movables from the house on Racławicka Street in which the air force staff was based. The movables were for the general. I saw three trucks loaded with various things drive off from our street, with the general inside. Once he was gone, there was only some colonel left, but I don’t know his name.
I heard that Rudolf served as a commander but I don’t know which unit he was in command of. Following the surrender, I saw Rudolf walk around various apartments and steal anything of value.
He finally left at the beginning of October 1944, accompanied by two trucks filled with things he had stolen from our neighborhood.
At that the report was concluded and read out.
