It was the pivotal battle that most historians believe turned the tide against the Nazis for good in World War II, resulting in a cascade of defeats as the Wehrmacht beat its retreat to Germany from the Soviet Eastern Front.
But it wasn't always that way, and in the opening months of Operation Barbarossa the German army seemed poised for a stunning victory against the Red Army.
As part of its push to secure the southern Caucasian oil fields, the German 6th Army was ordered to take the city of Stalingrad in September 1942, a move some historians believe was strategically irrelevant as the Nazis were already well on their way to Baku.

But many believe Adolf Hitler wanted to capture the city as a thumb in the eye to Soviet leader Josef Stalin, for whom the city was renamed.
Initially, the German army was able to push well into the city, taking the Univermag department store at its center. But the Red Army dug into the city's industrial areas along the banks of the Volga river and the battle ground down into a brutal street-by-street slugfest.
One of the Red Army's most accomplished generals, Marshall Georgi Zhukov, hatched a plan to surround the 6th Army and cut off its supply lines. And by mid-November, the Soviets began to squeeze the Nazis inside the city.
As winter descended, the Germans were running out of food, ammunition and other supplies, and when a rescue mission launched by Field Marshall Erich Von Manstein failed to break through, the Nazi's fate was sealed. The German forces under the command of Gen. Friedrich Paulus eventually surrendered in early February 1943.

It was a horrific battle waged on a titanic scale in a battlefield unlike any seen in modern times. In all, the Germans lost about 147,000 men in the battle while surrendering 91,000. The Soviets took even more catastrophic losses, with 480,000 dead and 650,000 wounded. An estimated 40,000 civilians were killed in the fighting.
