To arrange the events in order:
1. German forces try to take Moscow.
2. German troops run a siege of Leningrad.
3. The Germans take Stalingrad.
4. The Soviets surround Stalingrad.
5. The Soviets push the Germans to retreat.
Now, explaining Operation Overlord:
Operation Overlord was the codename for the Allied invasion of Normandy during World War II. It took place on June 6, 1944, and is also known as D-Day. The operation involved landing troops by sea and air on the beaches of Normandy, France, with the goal of establishing a foothold in Europe and eventually liberating it from Nazi control.
The operation was a massive coordinated effort involving troops from the United States, Great Britain, Canada, and other Allied nations. It was a turning point in the war as it opened up a second front in Europe, drawing German forces away from the Eastern Front where they were engaged with the Soviets. Operation Overlord marked the beginning of the end for Nazi Germany's control over Europe.
