What has been regarded as the darkest 24 hours in Australian military history which saw 5533 diggers killed, wounded or captured.has been remembered with a memorial service at the site.
More than 2,000 Australians were killed in the battle, but many of them were put into a mass grave by the Germans – a grave only uncovered in 2007.
Of those recovered, 205 have now been identified as Australian, three served with the British army, and 42 are still classified as unknown.
DNA technology has been able to positively identify 96 Australian soldiers whose inscribed tombstones were unveiled this week.
Thousands of Australians including family members of the identified soldiers, traveled to the Northern French province to pay their respects with Australian soil, eucalyptus leaves and flowers.
A horsedrawn wagon led the final coffin into the new Fromelles Military Cemetery, followed by Governor General Quentin Bryce and Prince Charles.
They watched on, accompanied by Minister for Veterans’ Affairs Alan Griffin, Chief of Army Lieutenant General Kenneth Gillespie and hundreds of families, a coffin carrying an unknown allied soldier was farewelled with full military honours.
"We are here to observe the end of a long silence," Ms Bryce said. "A near-century of questioning and not knowing, of loving hearts unrequited.
Identities of Fromelles soldiers released
Spending ANZAC day in France, not Gallipoli
Generations of absence, lives extinguished without explanation, missing without proper account. That is, until today."
