Between 1932 and 1945, hundreds of thousands of women and girls across Asia were forced into sexual slavery by the Imperial Japanese Army.

Referred to as "comfort women", they were taken from countries including Korea, China, Taiwan, the Philippines and Indonesia to be raped by Japanese soldiers.

Today, the issue remains a source of tension between Japan and its neighbours, with continuing campaigns to compensate the few surviving victims.

Dan Hardoon speaks to Chinese survivor Peng Zhuying who, along with her elder sister, was captured and taken to a "comfort station" in central China.

The Mount Vesuvius eruption that buried Pompeii in 79AD is well known, but far fewer people know about the last time the volcano erupted in 1944.

It was World War Two, and families in southern Italy had already lived through a German invasion, air bombardment, and surrender to the Allies.

And then at 16:30 on 18 March, Vesuvius erupted. The sky filled with violent explosions of rock and ash, and burning lava flowed down the slopes, devastating villages.

By the time it was over, 11 days later, 26 people had died and about 12,000 people were forced to leave their homes.

Angelina Formisano, who was nine, was among those evacuated from the village of San Sebastiano. She’s been speaking to Jane Wilkinson about being in the path of an erupting volcano.

In August and September 1939, tens of thousands of children began to be evacuated from Paris.

The move, part of France's 'passive defence' tactic, aimed to protect children from the threat of German bombardment.

Colette Martel was just nine when she was taken from Paris to Savigny-Poil-Fol, a small town more than 300km from her home.

She’s been speaking to her granddaughter, Carolyn Lamboley, about how her life changed. She particularly remembers how she struggled to fit in with her host family, and how it all changed because of a pair of clogs.

In 1940 a daring rescue operation began to help Allied servicemen escape from Nazi-occupied France.

French resistance fighter Roland Lepers was among those who guided stranded Allied soldiers and airmen to neutral Spain during World War Two. The 1,000 km route became known as the Pat O’Leary Escape Line - or the Pat Line.

It’s estimated 7,000 Allied personnel escaped through this route and similar escape lines, thanks to a network of people who clothed, fed and hid them. Peter Janes was one of those British servicemen.

Roland’s daughter Christine and Peter’s son Keith, speak to Jane Wilkinson about their fathers’ adventures.

In 1937, Japan invaded China committing atrocities including the Nanjing Massacre. Wang Jingwei was a Chinese national hero and second-in-command of China’s ruling Nationalist Party. He wanted to negotiate with Japan but his colleagues wouldn’t listen. So he defected, and in 1940 he agreed to lead a Japanese-controlled puppet government in Nanjing.

Many Chinese have hated him ever since – his name is synonymous with the word ‘Hanjian’, a traitor to China.

But Pan Chia-sheng’s memories of living under Wang Jingwei’s government tell a very different story. He speaks to Ben Henderson.

In 1949, Mildred Gillars – otherwise known as Axis Sally – became the first woman in American history to be convicted of treason.

The former Broadway showgirl broadcast antisemitic Nazi propaganda on German State Radio during World War Two.

Her weekly shows were heard by thousands of American servicemen who gave her the nickname Axis Sally.

After her capture, she denied being a traitor, but a jury in Washington convicted her of treason, and she served 12 years in prison. Jane Wilkinson has been looking through the BBC archives to uncover her story.

In December 1939, fascist Norwegian politician Vidkun Quisling travelled to Berlin from Oslo for a secret meeting with Adolf Hitler.

Quisling suggested to Hitler that the British were planning to move into Norway for their own strategic needs. Norway hadn’t been a concern for the Nazis but the meeting alarmed Hitler and within months Germany started its invasion of Norway.

From that moment, Quisling was consigned into history as a traitor. So much so that in the time since, his name has become a byword for traitor in numerous languages.

Matt Pintus hears from Norwegian journalist, Trude Lorentzen, who decided to study Quisling’s life after stumbling across his suitcase in an online auction.

As part of her voyage of discovery, Trude interviewed Quisling’s Jewish neighbour Leif Grusd who was forced to flee to Sweden when the Nazis took over Norway.

Leif Grusd's interview was translated from the NRK podcast "Quislings koffert" - Quisling's suitcase - released in 2021. It was made by production company Svarttrost for NRK.

In the autumn of 1945, World War II surrender ceremonies took place across the Japanese Empire. The one in China was held at the Forbidden City in Beijing bringing an end to eight years of occupation. Thousands of people watched the incredible moment Japanese generals handed over their swords. The United States, China, Russia and the United Kingdom were all represented. John Stanfield, now 103, is the last surviving British person who was there. He recalls to Josephine McDermott how he signed the surrender declaration documents on behalf of the British.

Vogue's war correspondent Lee Miller found herself in Adolf Hitler's Munich apartment when the news broke that he was dead.

Earlier that day, she and fellow photographer David Scherman had witnessed the harrowing scenes at the liberated Dachau concentration camp.

Lee Miller's son and biographer, Antony Penrose, explains to Josephine McDermott the significance of the photograph taken in the final days of World War II in Europe.

On 25 January 1933 the last legal communist march was held in Berlin.

Just a few days later Adolf Hitler became Chancellor of Germany.

Soon the Communist Party was banned and the Nazi grip on power was complete.

Eric Hobsbawm was a schoolboy communist at the time. He spoke to Andrew Whitehead in 2012.

In the early hours of 17 May 1943 a bold World War II attack destroyed two dams in the Ruhr Valley in Germany's industrial heartland, causing 1,600 casualties and catastrophic flooding which hampered the German war effort.

The dams were highly protected but 617 Squadron of the Royal Air Force had a new weapon – the bouncing bomb.

Invented by Barnes Wallis, the weapon was designed to skip over the dams' defences and explode against the sides.

The Dambusters mission was a huge propaganda success for Britain and later inspired a famous film.

In 2013, Simon Watts spoke to George "Johnny" Johnson, the last survivor of the Dambusters squadron.
