[ . . . ] When I pushed my way into the burning building with [my old colleague] Schneider, we had to climb over the bulging hoses of the Berlin fire brigade, although, as yet, there were few onlookers. A few officers of my department were already engaged in interrogating Marinus van der Lubbe. Naked from the waist upwards, smeared with dirt and sweating, he sat in front of them, breathing heavily. He panted as if he had completed a tremendous task. There was a wild triumphant gleam in the burning eyes of his pale, haggard young face. I sat opposite him in the police headquarters several times that night and listened to his confused stories. I read the Communist pamphlets he carried in his trouser pockets. They were of the kind which in those days were publicly distributed everywhere. And from the primitive hieroglyphics of his diary I tried to follow his trips down to the Balkans. The voluntary confessions of Marinus van der Lubbe prevented me from thinking that an arsonist who was such an expert in his folly needed any helpers. Why should not a single match be enough to set fire to the cold yet inflammable splendour of the Chamber, the old upholstered furniture, the heavy curtains, and the bone-dry wooden panelling! But this specialist had used a whole knapsack full of inflammable material. He had been so active that he had laid several dozen fires. With a firelighter, the 'Industrious Housewife', he had set the Chamber aflame. Then he had rushed through the big corridors with his burning shirt which he brandished in his right hand like a torch to lay more fires under the old leather sofas. During this hectic activity he was overpowered by Reichstag officials.
He also confessed to several smaller arson attacks in Berlin, the mysterious cause of which had aroused the attention of the Criminal Investigation Department. Several details suggested that Communist arsonists who had helped him in Neukölln and the Berlin Town Hall might have helped him with the Reichstag. The interrogating officers had pointed their investigations in this direction. But meanwhile things of a quite different nature had happened.
Shortly after my arrival in the burning Reichstag, the National Socialist elite had arrived. Hitler and Goebbels had driven up in their large cars; Göring, Frick and Helldorf arrived; Daluege, the police chief, was not there.
One of Hitler's chief adjutants came to look for me in the maze of corridors, now alive with the fire brigade and the police. He passed me Göring's order to appear in the select circle. On a balcony jutting out into the Chamber, Hitler and his trusty followers were assembled. Hitler stood leaning his arms on the stone parapet of the balcony and stared silently into the red sea of flames. The first hysterics were already over. As I entered, Göring came towards me. His voice was heavy with the emotion of the dramatic moment: 'This is the beginning of the Communist revolt, they will start their attack now! Not a moment must be lost!'
Göring could not continue. Hitler turned to the assembled company. Now I saw that his face was purple with agitation and with the heat gathering in the dome. He shouted uncontrollably, as I had never seen him do before, as if he was going to burst: 'There will be no mercy now. Anyone who stands in our way will be cut down. The German people will not tolerate leniency. Every Communist official will be shot where he is found. The Communist deputies must be hanged this very night. Everybody in league with the Communists must be arrested. There will no longer be any leniency for Social Democrats either.'
