The Warsaw Uprising of 1944 was the greatest and bloodiest military operation undertaken by any resistance movement in the Second World War. There were two uprisings in Warsaw and they are often confused. The first was the largest Jewish uprising of the war. In the spring of 1943 hundreds of Jewish fighters ferociously fought the German army in a desperate attempt to stop the final deportation of the remaining 60,000 Polish Jews from the Warsaw ghetto to the extermination camps. The second uprising - and the subject of this programme - mobilised thousands of Polish freedom fighters against the Nazis to liberate their capital city in the summer of 1944.
