Сталинградский фронт
In July 1942, three armies (the 1st, 5th and 7th Reserve Armies) out of the Supreme High Command reserve were moved into the Stalingrad sector and redesignated the 64th, 63rd and 62nd armies respectively. They formed the core of the Stalingrad Front on 12 July. The Stalingrad Front was then divided into the Stalingrad Front, under General Lieutenant V.N. Gordov, and the Southeastern Front, under Colonel General Andrei I. Yeremenko on 7 August 1942 as the Battle of Stalingrad began. Stalin had actually taken the decision to split the two fronts on 3 August at 0300 despite protest from his advisors. The Tsaritsa gully in Stalingrad was the dividing line. Yeremenko's new South-Eastern Front included the 51st, 57th, and 64th Armies. They were then re-transformed into the Don and Southwestern Fronts on 28 September with the Southeastern Front becoming the Stalingrad Front (Second Formation).
