On August 1, 1944, Poland’s pro-Western underground Home Army (Armia Krajowa — AK) took to arms in the nation’s capital, Warsaw. The insurgents fought for 63 days with hardly any help from the outside.
The Western Allies including the Americans, air dropped supplies against the opposition of the Soviets, who denied them landing rights. The airplane losses were enormous, and the flights to Warsaw were suspended. The Poles were abandoned completely.
