Germans have 5786 killed and 21,626 wounded while Romanian losses are 1874 killed and 6571 wounded.
First Battle of El Alamein. Rommel plans to ‘bounce’ British 8th Army with speed and daring, betting that the Allied positions are not prepared and the troops are ready to quit. Things go wrong from the beginning. 90th Light Division advances at 3 AM but strays into the minefields of the heavily defended coastal “box” manned by 1st South African Division. 15th and 21st Panzer Divisions attack further inland but are stopped by massed artillery fire and lose 18 tanks. Despite this, the Panzers overrun 18th Indian Infantry Brigade at Deir el Shein but are then repelled by an attack from British 1st Armoured Division, held as a mobile reserve. British have 2 advantages at El Alamein; first, being able to concentrate their artillery across the narrow front between the sea and the impassable Qattara Depression; second, a constant supply of ammunition brought up by rail from Alexandria.
