The front line stabilised and remained very much the same for the next two years to come. The future A19 extension partially overlaps a section of the British lines (over 1 km up to Turco Farm) and then continues towards the German forward trenches (High Command Redoubt) and the German occupied hinterland.
Between Turco Farm and Wieltje, Third Ypres began on the precise location where the A19 extension is planned.On 31st of July 1917 heavy fighting took place to the north, near Wood 15 and Hey Wood, where the A19 extension is planned.A large amount of ground won in Third Ypres was later again lost but the British kept the region through which the A19 would be extended.
