|Conflict||First World War, 1914-1918|
|Date from||12 October 1917|
As a part of the continuing Third Battle of Ypres on the Western Front, Australian, New Zealand and British troops were involved in an unsuccessful attempt to seize the Passchendaele Ridge from the defending Germans on 12 October 1917. The vicious fighting took place in the most appalling of waterlogged conditions, which helped render the name Passchendaele a synonym for slaughter. The 3rd Australian Division's attempts to struggle forward to their objective with little artillery protection represented the last major Australian participation in the Third Battle of Ypres.
