In Libya, Afrika Korps captures Derna on the coast road but most Allied troops have withdrawn overnight. 50 miles South, British, Australian and Indian troops dig in at Mechili (really more a series of trenches than a fort). Their defenses include 1 Cruiser tank, some armoured cars, 1 Bofors anti-aircraft gun, several “2 pounder” anti-tank guns and 1 “25 pounder” artillery piece. They expect reinforcements from British 2nd Armoured Division tanks but these have already withdrawn to the East. General Johannes Streich’s 5th Light Division has surrounded the fort but they do not attack due to sandstorms which jam the turrets on the 6 available Panzer tanks. Rommel is furious at Streich for the delay and orders an attack the following morning.
