<P> The Battle of Passchendaele ( German : Flandernschlacht , French : Deuxième Bataille des Flandres ) , also known as the Third Battle of Ypres , was a campaign of the First World War , fought by the Allies against the German Empire . The battle took place on the Western Front , from July to November 1917 , for control of the ridges south and east of the Belgian city of Ypres in West Flanders , as part of a strategy decided by the Allies at conferences in November 1916 and May 1917 . Passchendaele lay on the last ridge east of Ypres , 5 mi ( 8.0 km ) from a railway junction at Roulers , which was vital to the supply system of the German 4th Army . The next stage of the Allied plan was an advance to Thourout -- Couckelaere , to close the German - controlled railway running through Roulers and Thourout . </P>
