75 anniversary of Warsaw Uprising
https://en.wikipedia.org/wiki/Warsaw_Uprising
The Warsaw Uprising (Polish: Powstanie Warszawskie; German: Warschauer Aufstand) was a major World War II operation, in the summer of 1944, by the Polish underground resistance, led by the Home Army (Polish: Armia Krajowa), to liberate Warsaw from German occupation. The uprising was timed to coincide with the retreat of the German forces from Poland ahead of the Soviet advance.[10] While approaching the eastern suburbs of the city, the Red Army temporarily halted combat operations, enabling the Germans to regroup and defeat the Polish resistance and to raze the city in reprisal. The Uprising was fought for 63 days with little outside support. It was the single largest military effort taken by any European resistance movement during World War II.[11]
The Uprising began on 1 August 1944 as part of a nationwide Operation Tempest, launched at the time of the Soviet Lublin–Brest Offensive. The main Polish objectives were to drive the Germans out of Warsaw while helping the Allies defeat Germany. An additional, political goal of the Polish Underground State was to liberate Poland's capital and assert Polish sovereignty before the Soviet-backed Polish Committee of National Liberation could assume control. Other immediate causes included a threat of mass German round-ups of able-bodied Poles for "evacuation"; calls by Radio Moscow's Polish Service for uprising; and an emotional Polish desire for justice and revenge against the enemy after five years of German occupation.[12][13]
Initially, the Poles established control over most of central Warsaw, but the Soviets ignored Polish attempts to make radio contact with them and did not advance beyond the city limits. Intense street fighting between the Germans and Poles continued. By 14 September, the eastern bank of the Vistula River opposite the Polish resistance positions was taken over by the Polish troops fighting under the Soviet command; 1,200 men made it across the river, but they were not reinforced by the Red Army. This, and the lack of air support from the Soviet air base five-minutes flying time away, led to allegations that Joseph Stalin tactically halted his forces to let the operation fail and allow the Polish resistance to be crushed. Arthur Koestler called the Soviet attitude "one of the major infamies of this war which will rank for the future historian on the same ethical level with Lidice."[14]
Winston Churchill pleaded with Stalin and Franklin D. Roosevelt to help Britain's Polish allies, to no avail.[15] Then, without Soviet air clearance, Churchill sent over 200 low-level supply drops by the Royal Air Force, the South African Air Force, and the Polish Air Force under British High Command, in an operation known as the Warsaw Airlift. Later, after gaining Soviet air clearance, the U.S. Army Air Force sent one high-level mass airdrop as part of Operation Frantic.
