IN PASSAU, a picturesque Bavarian city at the confluence of the Danube, Inn and Ilz rivers, the Second World War is still being fought.

On one side are the respectable citizens of Passau and on the other, 33 year-old Anna Rosmus. Since she was a teenager she’s been obsessively trying to expose what she sees as the truth about her home town, an outwardly affluent and charming Catholic community.

Frau Rosmus has worked single-mindedly to expose Passau’s Nazi past since she wrote a schoolgirl essay on My Home Town During The Third Reich. She is known locally as ‘the nasty girl’ after the title of an Oscar-nominated movie based on her story. She has since exploded single-handedly the post-war conspiracy of silence that allowed prominent Passau Nazis to disguise themselves as former resistance men by publishing material that might not otherwise have appeared.

In return she has been spat on, called a Jewish Whore, threatened with death and had stones thrown at her. Frau Anna Rosmus still receives threatening phone calls and is told her house will be burned down. Today sees the publication of her book Wintergreen: Suppressed Murders, which records the mass murder and mistreatment of the Russians in 1945 and includes more than 300 names, including surviving local perpetrators and further documentation about the late Dr Franz-Maria Clarenz, a local obstetrician.

Earlier this month, the family of the late Dr Franz-Maria Clarenz of Passau took Rosmus to court over her allegations that the surgeon had carried out brutal late abortions on women from eastern Europe used as forced labour. The family won an order banning Frau Rosmus from repeating allegations that all the abortions were brutal and made at a late stage of pregnancy.

She faces a £200,000 fine or six months imprisonment if she refers to the alleged atrocities again.

The publisher expects the book to be stopped. Frau Rosmus thinks several ‘honourable citizens,’ perhaps ‘even the government’, may take her to court. And Bavaria’s criminal prosecutors will consider whether there are grounds for trials of any of those mentioned.

‘She makes untrue accusations,’ lawyer Klaus Zehner shouts, punching the air with his fist. ‘She selects her documents to fit her case.’ He doesn’t yet know what’s in her book.

The allegations are chilling. ‘Rosmus said that Clarenz performed abortions on mothers sometimes in the eighth month of pregnancy,’ says Zehner who fought the case. ‘Rosmus said the babies were wrenched out of the womb, limb by limb, and that the mothers, slave labourers, received no anaesthetic. That many of the babies forced into the world were left without food to die.

‘But this is not true. He performed over 200 abortions legally on eastern prisoners, under order of Hitler’s government,’ says Zehner. ‘There were no late abortions.’ He says they were natural births forced prematurely with medicine. ‘The mothers consented willingly and many babies survived and are still alive today.’

So why would a mother in an era before incubators want to induce birth at eight months? ‘They were women who had been frightened to have abortions and now wanted to be rid of their children because they knew the Russians were coming,’ he replies. ‘If the Russians found their women pregnant by Germans, they knew they would have an awful time.’

Frau Rosmus has painted the town brown. Behind the facade of caring Catholics and friendly bakers is a town which played host to three forced labour camps. Hitler lived here briefly, so too Heinrich Himmler. Anti-semitism is still rife. Passau is 80 per cent Catholic and officially there are no Jews registered, although Rosmus knows 19. ‘They are afraid to declare themselves,’ she said. The town’s Nazi constructed concrete Nibelung Hall is the annual meeting place for the far-Right Deutsche Volks Union. A local baker, she claims, makes swastika shaped bread for the occasion and the flea market sells SS memorabilia.

But Herr Riederer, a baker who recalls the Russian soldiers looting the shops and being executed afterwards, has never heard of the swastika bread. He is uneasy about Frau Rosmus’s other claims.

‘’Thomas Heller, an antiques dealer, who otherwise supports Frau Rosmus’s research, says it is strictly verboten to sell SS regalia. ‘She’s mad to say this.’

The town of 50,000 inhabitants is riven. Everyone has an opinion on ‘the nasty girl’ and, according to the letters to the local newspaper, the majority have had enough of her. Most think her motives pure, but there is a feeling that she should now be quiet.

She is seen as a woman obsessed. ‘There is a very bad taste and feeling in the town,’ says Gisa Schaffer-Huber. ‘We feel she’s doing it mostly for her own publicity.’

In the Fifties Passau’s town council removed all crosses marking Russian graves. In one cemetery, the desecration failed to wipe out the wintergreen, a hardy flower. The bones were exhumed in the Fifties and placed in a mass grave. Even the wintergreen has gone.

The nearby Innstadtfriedhof graveyard, set in the lush Bavarian forest, has stone crosses and metal plaques to commemorate the dead. Some were SS soldiers, some high-level perpetrators.

Back with Klaus Zehner in his gloomy office I ask whether he can help put me in touch with the family of the accused? ‘I am the accused,’ he says. ‘I’m the son-in-law of the deceased doctor.’

‘’‘’He feels outrage that Frau Rosmus has opened the wounds nearly 50 years after Clarenz was cleared of war crimes.

Frau Zehner says her father was patient, artistic and musical. ‘He only joined the Nazis to get a job.’ And what of anti-semitism? ‘I don’t have any Jewish friends. But my grandfather did.’

When I meet Frau Rosmus it is unexpectedly when she was broadcasting outside her home.

Inside there are two huge yellow cardboard Stars of David fringed with pencilled barbed wire and a massive collage depicting Moses. She is an unpredictable and volatile woman. Her eyes dart around fearfully. She wears a Star of David ‘out of sympathy’.

‘If I’m alone they say whatever they like. If I’m broadcasting they’re terrified.’ Now Rosmus, who has an open face, is natural and compelling. But her story contradicts the lawyer’s tale.

Back in town there is graffiti on a wall behind the cathedral with a Star of David daubed in red paint and the legend ‘Nazi raus.’ It means ‘Nazis piss off.’ On another wall, there is a poster advertising an anti-fascism disco, depicting a fist smashing a swastika.
