Battle of Alam el Halfa, Egypt. Rommel’s supply line are badly disputed by Allied sinking of Italian ships, while British 8th Army is building up with a steady stream of new equipment such as 6-pounder anti-tank guns from Britain and Sherman tanks from USA. Rommel plans his trademark penetration of Allied lines followed by a charge into their rearguard to force a panicked retreat and preempt any Allied attack. However, British General Montgomery knows his plans from Ultra intercepts and leaves a 12 mile stretch (from Alam Nayil to the Qattara Depression) lightly defended while concentrating anti-tank defenses 10 miles further East. After dark, Rommel’s tanks attack through the thin sector but are caught in expectedly dense minefields and lit up by Royal Navy Fairey Albacores dropping flares for RAF Wellington bombers to follow.
