The resistance put up by the Jews and bandits could be broken only by relentlessly using all our force and energy by day and night. On 23 April 1943 the Reichs Fuehrer SS issued through the higher SS and Police Fuehrer East at Cracow his order to complete the combing out of the Warsaw Ghetto with the greatest severity and relentless tenacity. I therefore decided to destroy the entire Jewish residential area by setting every block on fire, including the blocks of residential buildings near the armament works. One concern after the other was systematically evacuated and subsequently destroyed by fire. The Jews then emerged from their hiding places and dug-outs in almost every case. Not infrequently, the Jews stayed in the burning buildings until, because of the heat and the fear of being burned alive they preferred to ,jump down from the upper stories after having thrown mattresses and other upholstered articles into the street from the burning buildings. With their bones broken, they still tried to crawl across the street into blocks of buildings which had not yet been set on fire or were only partly in flames. Often Jews changed their hiding places during the night, by moving into the ruins of burnt-out buildings, taking refuge there until they were found by our patrols. Their stay in the sewers also ceased to be pleasant after the first week. Frequently from the street, we could hear loud voices coming through the sewer shafts. Then the men of the Waffen SS, the Police or the Wehrmacht Engineers courageously climbed down the shafts to bring out the Jews and not infrequently they then stumbled over Jews already dead, or were shot at. It was always necessary to use smoke candles to drive out the Jews. Thus one day we opened 183 sewer entrance holes and at a fixed time lowered smoke candles into them, with the result that the bandits fled from what they believed to be gas to the center of the former Ghetto, where they could then be pulled out of the sewer holes there. A great number of Jews, who could not be counted, were exterminated by blowing up sewers and dug-outs.
