For the past several days, huge clouds of smoke have been rising up over the ghetto, and at night tremendous flames are seen over the northern part of the city. Special loudspeakers ceaselessly call on the inhabitants of the ghetto to surrender. Some of the Jews obeyed the substance of these appeals. Fewer than 10,000 persons lined up at the concentration points named by the Germans and were taken outside of Warsaw. But these were old people, including many women, the aged and weak among the men. All the rest, mainly young men, numbering more than 20,000, are fighting stubbornly. It is quite clear that in this battle the Jewish side is also suffering heavy losses. But it is a fact that in the six days that have passed since the Germans began the Aktion against the Warsaw ghetto, the Jews have not suffered defeat, and they reveal absolute determination to continue their self-defense and the struggle, and it looks as though it may continue for a longer period.
This war between the Jews and the Germans has awakened feelings of sympathy and admiration on the Aryan side of Warsaw, and shame among the Germans, who feel rightly that the situation that has come about in Warsaw is an uncommon blow to German prestige. It now appears that the Gestapo, which knows all and can do all, did not succeed in preventing the excellent preparations made by the Jewish population for the struggle and for its defense, with the result that the combined forces of the Gendarmerie, the SS and the Army were unable up to now to overcome this resistance despite the assaults they have been mounting for the past six days..."
