Book excerpt: A detailed and highly illustrated account of the Polish II Corps' (or 'Anders Army') perilous journey to fight side by side with Allied forces at the height of World War II. Following the conquest of Poland by Nazi Germany and the Soviet Union in 1939, hundreds of thousands of Polish families were torn from their homes and sent eastwards to the arctic wastes of Siberia. Prisoners of war, refugees, those regarded as 'social criminals' by Stalin's regime, and those rounded up by sheer chance were all sent 'to see the Great White Bear'. However, with Hitler's invasion of the Soviet Union in Operation Barbarossa just two years later, Russia and the Allied powers found themselves on the same side once more. Turning to those that it had previously deemed 'undesirable', Russia sought to raise a Polish army from the men, women and children that it had imprisoned within its labour camps. In this remarkable work, renowned historian Professor Norman Davies draws from years of meticulous research to recount the compelling story of this unit, the Polish II Corps or 'Anders Army', and their exceptional journey from the Gulag of Siberia through Iran, the Middle East and North Africa to the battlefields of Italy to fight shoulder-to-shoulder with Allied forces. Complete with previously unpublished photographs and first-hand accounts from the men and women who lived through it, this is a unique visual and written record of one of the most fascinating episodes of World War II.
