The First Battle of Passchendaele took place on 12 October 1917 during the First World War, in the Ypres Salient in Belgium on the Western Front. The attack was part of the Third Battle of Ypres and was fought west of Passchendaele village. The British had planned to capture the ridges south and east of the city of Ypres 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 the railway junction at Roulers, which was an important part of the supply system of the German 4th Army. After a dry spell in September, rains began on 3 October and by the Battle of Poelcappelle on 9 October much of the British field artillery opposite Passchendaele was out of action due to rain, mud and German artillery-fire. The remaining guns were either left in old positions and fired at the limit of their range or were operated from any flat ground near wooden roadways or from platforms, many of which were unstable, where it was found impossible to move them forward.
