The Warsaw insurgents, who had entered the canals during the fighting, remember them today as one of their worst survivors. Dirty, dark and smelly, however, saved lives. The Old Town for more than half of August 1944 was the arena of the most bloody fighting of the uprising. Cut off from the other districts waiting for destruction. The commander decided to evacuate to Srodmiescie. Some had to go through the canals, and the rest were up. The entire operation assumed the greatest possible withdrawal, which was to continue fighting in other districts. Only in this way could one fool the enemy who cut off all the other escape routes. The evacuation took place only in one place. The Germans fired and the crowd of civilians pressed on, treating them to death. They all wanted to get out of this hell. The gendarmes guarding the descent into the sewers did not let anyone in because the Germans had pumped gasoline into them, which they then fired. Insurgents had to wait. The wounded were often dropped. There were times when people simply fell straight into a cold, hideous liquid flowing downstairs. The first contact with her was not the most pleasant. The worst was the stink. They had exhausted a few weeks of fighting, carrying weapons and wounded, and had to travel almost four feet, some of the passages were only 1.5 meters high. The dead were in the canal regularly. For many, such a view was unbearable. They could not stand psychologically. He had the impulse as too high a water level to panic. The rest had to reassure them immediately that they did not start screaming. It was rumored that they could hear the Germans. They were waiting at the top of the hatches, which they opened from time to time, throwing grenades in. Betrayal could have the slightest noise. Despite the underground tragedy, the channels undoubtedly played a positive role in the uprising. They allowed to save several thousand people, proving the remarkable ingenuity of the Poles. Erich von dem Bach-Zelewski, responsible for the pacification of the insurrection, admitted that Germany had completely ignored the fact that the channels could be used for such purposes.
