There is a chapter of World War 2 history that remains largely untold: the story of the fourth largest Allied military of the war, and the only nation to have fought in the battles of Leningrad, Arnhem, Tobruk and Normandy. This is the story of the Polish forces during the Second World War, the story of millions of young men and women who gave everything for freedom and in the final victory lost all. In a cruel twist of history, the monumental struggles of an entire nation have been largely forgotten, and even intentionally obscured.
