In July the battery switched to Second Army in the Ypres Salient, supporting the Third Ypres Offensive. This made little progress, and Second Army took over its direction. The Battles of the Menin Road, Polygon Wood and Broodseinde were highly successful because of the weight of artillery brought to bear on German positions. But as the offensive continued with the Battle of Poelcappelle and First and Second Battles of Passchendaele, the tables were turned: British batteries were clearly observable from the Passchendaele Ridge and were subjected to Counter-battery fire, while their own guns sank into the mud and became difficult to aim and fire.
