The action of 22 October 1917 was an attack during the Third Battle of Ypres in the First World War by the British Fifth Army and the French First Army against the German 4th Army. British attacks had been repulsed at Passchendaele by the 4th Army at the Battle of Poelcappelle (9 October) and the First Battle of Passchendaele (12 October). While the British waited for another dry spell and the completion of plank roads up to the new front line, the Canadian Corps and fresh British divisions were transferred to Flanders by the British Expeditionary Force (BEF).
