The Warsaw uprising was the largest single operation undertaken by any resistance movement during World War Two. The Armia Krajowa – The Polish Resistance Home Army were aiming to liberate the city of Warsaw from the occupying forces of Nazi Germany.
Ultimately the uprising failed when the Soviet armies halted their advance short of Warsaw – allowing the German forces breathing room to regroup and demolish the city and quell the uprising.
The only real outside support came from the nightly drops of supplies from the RAF, other commonwealth air forces and of course units of the Polish Air Force.
There was no difficulty in finding Warsaw. It was visible from 100 kilometers away. The city was in flames but with so many huge fires burning, it was almost impossible to pick up the target marker flares. — William Fairly, a South African pilot, from an interview in 1982
