The Third Battle of Ypres required successive Allied attacks to push through the German 4th Army's defenses near Ypres. Anglo-French forces planned a broad assault from Bixschoote in the north to the Gheluvelt Plateau in the south, supported by artillery and air observation, aiming to seize key ground on the Western Front.
On 16–18 August 1917, Allied forces attacked along the front near Ypres. The French First Army achieved significant gains on the northern flank, and British forces advanced northward from St Julien. However, the assault on the Gheluvelt Plateau failed to reach its objectives, and German counter-attacks reclaimed most of the ground there. Persistent rain, flooded shell holes, and mud severely hampered infantry mobility and artillery observation.
German defensive success and relentless rain forced the British to suspend offensive operations for three weeks. During this pause, roads were rebuilt, fresh divisions and artillery were transferred, and tactics were revised. The main effort shifted southward, enabling the subsequent successful advances at the Battles of Menin Road Ridge, Polygon Wood, and Broodseinde in September–October 1917.
