Which Allied victory marked a crucial turning point in the North African campaign?

The Battle of El Alamein is widely recognized as a significant turning point in the North African campaign during World War II. Fought between October 23 and November 11, 1942, this battle was a key engagement between the British Eighth Army, commanded by General Bernard Montgomery, and the Axis forces led by Field Marshal Erwin Rommel.

The victory at El Alamein halted the advance of Axis powers into Egypt and effectively prevented further threats to the Suez Canal, which was vital for maintaining Allied supply lines to the Middle East. Moreover, the successful defense at El Alamein marked the beginning of a series of offensive operations that would ultimately lead to the expulsion of Axis forces from North Africa. This battle not only boosted Allied morale but also demonstrated the potential of a unified Allied effort, laying crucial groundwork for subsequent campaigns in Italy and Europe.

While the other options represent important events in World War II, they relate to different theaters of conflict or phases of the war and do not have the same significance as the Battle of El Alamein in the context of the North African campaign.
