Operation Uranus
Russian generals Aleksandr and Georgy Zhukov organized Russian troops. They ordered the troops to settle in the mountains to the west of the city as well as to the north. From there the forces initiated Soviet strategic operation called Operation Uranus.
Red Army on November 19 launched Uranus under the command of Gen. Nikolay Vatutin. The operation aims to destroy the German forces in and surrounding the city of Stalingrad.
The operation was both indecisive and chaotic as no preparations were made in response to the fights. The attacks penetrated deep in the flanks. By late November, the two German armies successfully build the defensive trap, trapping around 300,000 other and Axis troops. With winter setting in, the main supplies like food and medical supplies began dwindling making the forces starve and become weaker.
