Poland was the 'tripwire' that brought Britain into the Second World War, but it was largely the fear of the new Nazi-Soviet Pact rather than the cementing of an old relationship that created the formal alliance. But neither Britain, nor Poland's older ally, France, had the material means to prevent Poland being overrun in 1939. The broadcast, 'Poland is no longer alone' had a distinctly hollow ring. During the next four years the Polish Government in exile and armed forces made a significant contribution to the allied war effort; in return the Polish Home Army received a paltry 600 tons of supplies. Poland Alone focuses on the bloody Warsaw Uprising of 1944, when the Polish Resistance attempted to gain control of their city from the German Army. They expected help from the Allies but received none, and they were left helpless as the Russians moved in. The War ended with over five million Poles dead, three million of whom died in the concentration camps.

Jonathan Walker examines whether Britain could have done more to save the Polish people in their crisis year of 1944, dealing with many different aspects such as the actions of the RAF and SOE, the role of Polish Couriers, the failure of British Intelligence and the culpability of the British Press.
