How did Montgomery defeat Rommel at El alamein?

At the Second Battle of El Alamein in late 1942, British General Bernard Montgomery defeated German General Erwin Rommel by implementing a well-planned strategy that combined strong defensive positions with a massive infantry and armor assault. Montgomery's forces outnumbered Rommel's and were better supplied, allowing for sustained attacks and the use of artillery to weaken German defenses. Key tactics included the use of deception to mask troop movements and the effective coordination of air support. Ultimately, these factors led to a decisive victory for the Allies, marking a turning point in the North African campaign.
