 On 26 September, the 4th and 5th Divisions attacked and captured Polygon Wood, while later on 4 October, another successful attack was made on the main ridge at Broodseinde, where the four Australian divisions involved fought side by side, as they clashed head on with a German counterattack that had been launched at the same time the Australians had risen to carry out their assault.The result was a rout by the Australians, as the German line broke and following further attacks against German pillboxes, the ridge was captured.The first two attacks had been successful and as Allied commanders began to believe that a breakthrough was possible further attacks were made at Poelcappelle on 9 October and at Passchendaele on 12 October despite heavy rain that turned the ground into a muddy quagmire.
