HALIK KOCHANSKI is the author of the award-winning Resistance, a sweeping account of the underground war across Nazi-occupied Europe. She tells a much more complex story than usual of subversion, SOE, partisans and civil war, as well as desperate Jewish defiance.

The music in this episode is from Ida Pinkert's 'Four Songs', played by the Nimrod Ensemble of Berlin as part of the Lebensmelodien project, which seeks to rediscover the lost music of composers affected by the Holocaust (www.lebensmelodien.com).
