Marcoing played a strategic role in the functioning of the Hindenburg Line. Shielded by the support line and connected by rail and canal to Cambrai, the commune was used for the stationing of troops. However, it was taken on 20th November 1917 by the unstoppable advance of the tanks. But the delay in sending reinforcements hindered the continuation of the advance on Cambrai. The village was retaken by the Germans and not liberated until September 1918.
