The Second Battle of El Alamein (23 October – 11 November 1942) was a battle of the Second World War that took place near the Egyptian railway halt of El Alamein. The First Battle of El Alamein and the Battle of Alam el Halfa had prevented the Axis from advancing further into Egypt.

The Allied victory was the beginning of the end of the Western Desert Campaign, eliminating the Axis threat to Egypt, the Suez Canal and the Middle Eastern and Persian oil fields. The battle revived the morale of the Allies, being the first big success against the Axis since Operation Crusader in late 1941. The end of the battle coincided with the Allied invasion of French North Africa in Operation Torch on 8 November, which opened a second front in North Africa.
