The battle of Fromelles on 19 July 1916 was a bloody initiation for Australian soldiers to warfare on the Western Front. Soldiers of the newly arrived 5th Australian Division, together with the British 61st Division, were ordered to attack strongly fortified German front line positions near the Aubers Ridge in French Flanders. The attack was intended as a feint to hold German reserves from moving south to the Somme where a large Allied offensive had begun on 1 July. The feint was a disastrous failure. Australian and British soldiers assaulted over open ground in broad daylight and under direct observation and heavy fire from the German lines. Over 5,500 Australians became casualties. Almost 2,000 of them were killed in action or died of wounds and some 400 were captured. This is believed to be the greatest loss by a single division in 24 hours during the entire First World War. Some consider Fromelles the most tragic event in Australia’s history. https://www.awm.gov.au/articles/encyclopedia/fromelles

On the top of Kasselberg once stood about twenty windmills. The last mill caught fire on October 30, 1911, which could be seen far into the surrounding area. In 1947, the Ruytoor mill in Arneke was purchased by the local Syndicat d'Initiative, to be opened to the public on July 14, 1949. The mill has two different installations: it functions as a gristmill, which produces organic flour. An electric installation functions as an oil mill, for the production of both rapeseed oil and linseed oil. Near the mill, there is an orientation table and a statue of Maréchal Foch.

Near the front line in 1916, a fierce battle was fought between the British (Australians) and the Germans. To commemorate 'la bataille' and the wounded who were brought back from the battlefield, a monument/statue was erected here.

Anecdote: During the battle, Sergeant Simon Fraser heard a wounded soldier cry out, "Don't forget me, cobber!" Despite the danger, Fraser returned to the battlefield to save the man, an act of bravery that was later immortalized in the statue. This event emphasizes the sacrifice and strong bond between soldiers during the horrors of war.
