Second Army HQ took over the faltering offensive in September, and the battery came under its control. 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 British batteries were clearly observable from the Passchendaele Ridge and were subjected to counter-battery (CB) fire, while their own guns sank into the mud and became difficult to aim and fire.
