One of only two surviving babies born at Auschwitz appeared at a war crimes trial in Germany today to confront a guard accused of being complicit in the mass murders of 300,000 Hungarian Jews.

Angela Orosz, now 70, looked into the eyes of 93-year-old former S.S. man Oskar Groening and said: 'We cry still over the ones that you have taken from us, Mr. Groening. How can I ever forgive?'

Groening, who admitted his moral but not legal guilt at the start of his trial in the city of Luneburg a month ago, did not look directly at his accuser.

No redemption: Angela Orosz, now 70, said she was unwilling to forgive 93-year-old former S.S. man Oskar Groening (right) for his complicity in the mass murders of 300,000 Hungarian Jews

She began by saying: 'I would like to stand here and direct the accusing finger against those who were responsible for the inhuman conditions in which I born was - like you, Mr. Groening.'

As one of only two babies known to have survived the slaughterhouse in occupied Poland where the Nazis murdered at least 1.2 million people, she added: 'I survived for a reason, because I have a mission to speak for those who cannot speak.'

In harrowing detail the small, black-clad woman reported sterilization experiments by evil camp doctor Josef Mengele - known as the 'Angel of death' among inmates - on her mother, in the seventh months of pregnancy.

Again and again, burning substances had been injected inside her mother.

'Directly behind the foetus...that was me. These experiments are the reason that I have no brothers or sisters.' She was born in the campon December 21 1944.

Because her mother got so little to eat she was so small that her pregnancy was not noticed. At the secret birth - if the S.S. had known she was born she would have been immediately killed - she weighed only one kilogramme.

'I was so malnourished, I could not scream. That's the only reason that I survived,' she said to a hushed courtroom which has already heard a litany of horrors from previous Auschwitz survivors.

Three hours after her birth, and wearing 'only shreds,' her mother ran barefoot to the parade ground Appell where inmates were counted: not to have appeared would have meant her execution.

Five weeks after Angela's birth the premier extermination camp of the Third Reich was liberated by soldiers of the Red Army.

Repeatedly during her testimony Mrs. Orosz turned directly to address Groening who was accompanied by two paramedics as his health grows increasingly fragile.

'Maybe my pretty mother was met by you on the ramp,' she said, referring to the notorious train siding where the doomed Jews of Europe arrived to be sorted into slave labourers and those earmarked for immediate gassing.

On trial: Known as the 'Bookeeper of Auschwitz,' Groening was responsible for sorting the possessions of those who arrived and shipping them back to his S.S. superiors in Berlin to fuel the Nazi war effort

'Mr. Groening, did you know what happened?' She did not receive a response as Groening looked at a wall and then looked down.

She said that for the rest of her life her mother 'could not shower, but only bathe. Until her death she had a fear of barking dogs' - the S.S. greeted every train with snarling Alsatians that menaced the new arrivals.

She added that her mother died of cancer and during her illness had nightmares about Dr. Mengele. 'He stood in the door,' she said, 'and no morphine could rid her of these visions. I tremble in love for her.'

'We cry still over the ones that you have taken from us, Mr. Groening. How can I ever forgive?' she added.

Telling the former SS guard that today was the birthday of her father, she said. 'Mr. Groening, I cannot go to my father's grave and say a prayer, because he has none.

'Somewhere, his ashes are scattered in Auschwitz. Auschwitz is the grave of my father.'

Unimaginable loss: Angela Orosz's whole family died in Auschwitz, with the exception of her mother

Now resident in Montreal, she is expected to be the last co-plaintiff in the case to give evidence against Groening on behalf of the German state.

She said afterwards: 'I brought my grandson so, if he has a family one day, he can tell them about the horrors of the Holocaust. This is needed now more than ever.

'Now we have openly have anti-Semitism again everywhere and the world is still watching.'
