Witness History: World War 2 Collection

How sex, jazz and 'fake news' were used to undermine the Nazis in World War Two. In 1941, the UK created a top secret propaganda department, the Political Warfare Executive to wage psychological warfare on the German war machine. It was responsible for spreading rumours, generating fake news, leaflet drops and creating fake clandestine German radio stations to spread misinformation and erode enemy morale. We hear archive recordings of those involved and speak to professor Jo Fox of the Institute of Historical Research about the secret history of British "black propaganda".

Hear how the BBC reported the Allied invasion of Nazi-occupied France on June 6th 1944. The operation was a crucial step in the liberation of western Europe. Using original BBC reports from the time - from Chester Wilmot, Richard Dimbleby, Robin Duff, Ward Smith and Alan Melville - we tell the story of D-Day.

At the end of WW2 much of Germany's capital had been destroyed by bombing and artillery. Almost half of all houses and flats had been damaged and a million Berliners were homeless. Caroline Wyatt has been speaking to Helga Cent-Velden, one of the women tasked with helping clear the rubble to make the city habitable again.

Thousands of Allied troops parachuted into the Nazi-occupied Netherlands in September 1944. At that point, it was the most ambitious Allied airborne offensive of World War Two. British, American and Polish troops were dropped behind German lines in an attempt to capture a series of bridges on the Dutch/German border. Mike Lanchin has spoken to Hetty Bischoff van Heemskerck who, as a young woman, watched the Allied paratroopers come down close to her home in the city of Arnhem.

Mountaineers risked their lives to camouflage churches and palaces in the great Russian city during World War Two. The city was besieged by the Germans and under bombardment. The climbers used paint and canvas to conceal the landmarks from enemy attack. Mikhail Bobrov was just 18 years old when first got sent up the city's spires. He's been speaking to Monica Whitlock about his wartime experiences. Photo: A climber suspended from a spire in Leningrad. Credit: Tass/PA.

Soon after Hitler ordered the invasion of Hungary in March 1944, the Nazis began rounding up hundreds of thousands of Hungarian Jews. Most were immediately sent to their deaths in the concentration camps at Auschwitz-Birkenau. David Gur was a member of the Jewish Hungarian underground, who helped produce tens of thousands of forged identification documents. These allowed Jews to hide their true identities and escape deportation to the death camps. Now 91 years old, David has been telling Mike Lanchin about his part in one of the largest rescue operations organised by Jews during the Holocaust. Photo: False Hungarian ID document (BBC)

Italy's great works of art were threatened by bombing and looting during World War Two. But a plan known as 'Operation Rescue' was devised to keep the paintings and sculptures safe. Some were hidden in remote spots, others were moved to the Vatican. Pasquale Rotondi was a leading figure in the operation, his daughter Giovanna Rotondi spoke to Alice Gioia about his wartime work.

Around 80 thousand women and girls volunteered to join the Women's Land Army during the Second World War. They helped provide vital food supplies to a country under siege. Kirsty Reid has spoken to Mona McLeod who was just 17 years old when she started working 6 days a week on a farm in Scotland. Mona has written a book about her experiences: 'A Land Girl's Tale'.
