The battle of Broodseinde Ridge was the third operation launched by British general Herbert Plummer as part of the Ypres offensive of 1917. It was a large operation, involving twelve divisions, including those of both I and II ANZAC. The attack was planned on the same basis as its predecessors - the attacking troops' objectives were approximately 1,500 metres deep, the advance would be preceded by a massive artillery bombardment; and a creeping barrage would lead the troops on to their objectives and then protect them while they consolidated their positions.

The attack began before dawn on 4 October 1917. The Australian troops involved were shelled heavily on their start line and a seventh of their number became casualties even before the attack began. When it did, the attacking troops were confronted by a line of troops advancing towards them; the Germans had chosen the same morning to launch an attack of their own. The Australians forged on through the German assault waves and gained all their objectives along the ridge. It was not without cost, however. German pillboxes were characteristically difficult to subdue, and the Australian divisions suffered 6,500 casualties.
