Hi Matthew,
Fromelles was "the battle that never happened" because it was overshadowed by the huge Battle of the Somme that began a couple of days later. On the first day of the Battle of the Somme the British lost over 36,000 men.
By comparison, Fromelles was a minor side show of little strategic importance and only cost a mere 9,000 men. This is what's known as "The Devil's Arithmatic"
Fromelles is remembered in Australia because it marked the first major battle the Australian's fought in on the Western Front, and the single worst day in our military history.
In fact the Australian government conspired to keep the news of our terrible losses at Fromelles from the Australian people by refusing to give official accounts of the battle to the newspapers until long after the Somme campaign had ground to a halt. There was no way they could hide the scale of the tragedy once the death notices started to be delivered to relatives.
Fromelles marked Australia's brutal initiation to fighting on the Western Front. Our forces had only recently arrived in France after a period of rest and reorganisation after the disasterous Gallipoli campaign, when we lost 8,500 men over a 7 month period. Australia lost 5,533 men in one day at Fromelles.
Australian casualties at Fromelles in one 24 hour period were greater than the Australian losses in the Boer War, Korean War and Vietnam War combined.
After Fromelles, the 5th Division was withdrawn from the front. The survivors could barely reach battalion strength. It took almost 12 months to build the 5th Div back up to fighting strength after Fromelles.
After the battle the Germans buried many of the dead Australians in unmarked mass graves on the edge of the village. The Fromelles battlefield became the scene of further slaughter in 1917 during the German Offensive, and any evidence of the earlier mass graves from 1916 was destroyed.
It's wonderful to see that almost 90 years after they fell, these men are remembered and honoured for their sacrifice and service. May they rest in peace.
