Libya. In the morning, Italian Trieste Division finds a way through the British minefields to bring up supplies, despite heavy shelling from the British “boxes”. British General Ritchie is still slow in organizing an attack on the trapped Panzers with his greater number of tanks. In the Cauldron, Rommel pulls back to a series of ridges and hollows just East of the minefields which now serve to protect his flank. He uses a dense sandstorm to dig in anti-tank guns on the Sidra and Azlagh Ridges as a trap for the British armour. Afrika Korps commander General Ludwig Crüwell, leading the attack along the coast, is flying over the front line when he strays over British 150th Brigade “box” and his Storch light aircraft is shot down. The pilot is killed by the gunfire, the Storch crash lands and Crüwell is captured.
