Four months earlier after the loss of Tobruk , Rommel’s forces were in the ascendancy. Prime Minister Winston Churchill removed General Auchinleck from Command of Eighth Army and appointed Bernard Montgomery in his place. After the successful defense of Alam El Halfa Ridge in late August and early September ended Rommel’s inexorable advance, Montgomery set in train plans for the set piece offensive campaign at El Alamein which took place between 23 October and 4 November 1942.
The stakes could not have been higher. Had Rommel broken through the Allied defenses in Summer 1942 or Montgomery’s forces not overwhelmed the German and Italian armies at El Alamein, Egypt and the Suez Canal would have fallen to the Nazis.
Instead, the victory at El Alamein proved to be the turning point of the War against Hitler and led to the victory in North Africa.
