Passage: The Commonwealth forces practised a number of deceptions in the months before the battle to confuse the Axis command as to the whereabouts of the forthcoming battle and when the battle was likely to occur. This operation was codenamed Operation Bertram. In September, they dumped waste materials (discarded packing cases, etc.) under camouflage nets in the northern sector, making them appear to be ammunition or ration dumps. The Axis naturally noticed these but, as no offensive action immediately followed and the "dumps" did not change in appearance, they were subsequently ignored. This allowed Eighth Army to build up supplies in the forward area unnoticed by the Axis, by replacing the rubbish with ammunition, petrol or rations at night. Meanwhile, a dummy pipeline was built, hopefully leading the Axis to believe the attack would occur much later than it, in fact, did and much further south. To further the illusion, dummy tanks consisting of plywood frames placed over jeeps were constructed and deployed in the south. In a reverse feint, the tanks destined for battle in the north were disguised as supply trucks by placing removable plywood superstructures over them.

Question: What enemy did the Commonwealth confuse?
