civilian inhabitants of Warsaw became increasingly tragic. Constant bombardment of civilian facilities, lack of food and medical supplies resulted in heavy casualties among the city's population. The water works were destroyed by German bombers and all boroughs of Warsaw experienced a lack of both potable water and water with which to extinguish the fires caused by the constant bombardment. Also, the strategic situation became very difficult. The Soviet Union's entry into the war and lack of support from the Western Allies made the defence of the city pointless and heavily demotivated the volunteers in participating in any further military actions. On September 26, Army Warsaw General Juliusz Rómmel, started capitulation talks with the German commander. On September 27, at 12:00 a cease fire agreement was signed and all fighting halted. Soon afterwards, Warsaw capitulated. Several units declined to put down their weapons and cease fire, and their commanding officers had to be visited by generals Czuma and Rómmel personally. On September 29, the garrison of Warsaw started to hide or destroy their heavy armament. Some of the hidden war material was later used during the Warsaw Uprising. On September 30, the evacuation of Polish forces to German prisoner of war camps started and, the following day, German units entered the capital. City was occupied until January 17, 1945.
