Russians transmited some radio broadcasts. In those broadcasts Russians were calling people of Warsaw to begin the Rising - and they promised to help.why did the Warsaw people thought that Red Army will help them during the uprising?
Most of them remembered that very well - and they knew what will happen in Poland in the future, if the Red Army liberate all Poland, and they will do nothing - they knew that if such thing happen, Poland will be probably communistic satelite of USSR...Hey they should have rememberd 1939 to keep in mind what they have to expect from the USSR.
Remember that before the Rising, Poland had two Governments - one, communistic Government in Lublin, which was established by Soviet Union
And second - Polish Government in exile, in Great Britain - it was heir of legally valid Polish pre-war Government
Communistic Government had been never accepted by Government in exile, and inversely.
Home Army accepted only independent Polish Government in Great Britain, and it didnt want puppet Communistic Government to rule in Poland - which would in fact mean that Stalin rules in Poland.
They didnt trust them - but this was the last chance for independent Poland, so they had to try.why did they trust them?
Although they didnt trust them, they knew that Berling's Polish Army is advancing together with Red Army - they knew that it will try to help and they knew that Berling will try to convince Stalin to help Warsaw.
And Berling's Army tried to help - but without permission from Stalin - and, fighting alone without air and heavy artillery support, it had to withdraw from left bank Warsaw.
Also remember, that Warsaw Uprising was only a small part of much greater operation - Operation Tempest - read this article:
Poles were also counting on USA, GB, and Polish Forces in the West help - especcialy they counted on Sosabowski's Parachute Brigade help - even when that Brigade had been formed, there had been a plan that in the future it would land somewhere in Poland to help Home Army.
But instead in Warsaw, it landed in Arnhem and took part in Operation Market Garden trying to liberate Holland (not Poland)
Poles didnt trust Soviets, although they had some reasons to thought that Soviet Forces would help Poles if Poles would start to fight with Germans before Soviets arriving (for example radio broadcasts), contrary to all what happened in 1939 and later.
Some fragments from wikipedia articles about Operation Tempest and Warsaw Uprising:
On January 2, 1944, Red Army forces of the 2nd Belarusian Front crossed the prewar Polish border. At the same time, massacres of Poles in Volhynia reached their peak and the 27th Polish Home Army Infantry Division was formed. Thus began Operation Storm. The Division managed to contact the commanders of the advancing Red Army and began successful joint operations against the Wehrmacht. Together they retook Kowel (April 6) and Włodzimierz. The Division was, however, soon forced to retreat west, and in the Polesie area was attacked by both German and Soviet forces. Polish soldiers taken prisoner by the Soviets were given the choice of joining the Red Army or being sent to Soviet forced-labor camps. The remnants of the Division crossed the Bug River, where they were attacked by Soviet partisan units. After liberating the towns of Lubartów and Kock, the Division (reduced to some 3,200 men) was surrounded by the Red Army and taken prisoner.
Regards!The Uprising began at a crucial juncture as the Soviet Army was approaching Warsaw. The Uprising's chief objective was to drive the German occupiers from the city, helping with the larger fight against the Axis. Secondary political objectives were to liberate Warsaw before the Red Army arrived, so as to underscore Polish sovereignty, and to undo the Allied division of Central Europe into spheres of influence. Polish authorities were to reappear in liberated Warsaw and challenge the Soviet puppet government that was to rule Poland.
