In 1941, three brothers witnessed their parents and two other siblings being led away to their eventual murders. It was a grim scene that would, of course, be repeated endlessly throughout the war. Instead of running or giving in to despair, these brothers -- Tuvia, Zus, and Asael Bielski -- fought back, waging a guerrilla war of wits against the Nazis. By using their intimate knowledge of the dense forests surrounding the Belarusan towns of Novogrudek and Lida, the Bielskis evaded the Nazis and established a hidden base camp, then set about convincing other Jews to join their ranks. As more and more Jews arrived each day, a robust community began to emerge, a "Jerusalem in the woods." After two and a half years in the woods, in July 1944, the Bielskis learned that the Germans, overrun by the Red Army, were retreating back toward Berlin. More than one thousand Bielski Jews emerged -- alive -- on that final, triumphant exit from the woods.Duffy, Peter is the author of 'Bielski Brothers The True Story of Three Men Who Defied the Nazis, Built a Village in the Forest, and Saved 1,200 Jews', published 2004 under ISBN 9780060935535 and ISBN 0060935537.
