The Gheluvelt Plateau actions, July–August 1917 took place from 31 July to 27 August, during the Third Battle of Ypres (31 July – 10 November 1917) in Belgium, in the First World War. The British Fifth Army and the German 4th Army fought for possession of the plateau at the highest part of the ridges to the south-east, east and north-east of Ypres in West Flanders. The 4th Army had been building defensive positions in the Ypres Salient since 1915 and the Gheluvelt Plateau was the most fortified section of the front. The Fifth Army had made the plateau its main objective during the Battle of Pilckem Ridge (31 July – 2 August) but the II Corps advance was contained short of its objectives and German counter-attacks later recaptured some ground.
