By strongly attacking toward Voronezh, near the site of the German's deepest penetration the year before, it would hide the nature of the real action taking place far to the south.
The plan involved forces of Army Group South, at this time far north of their ultimate area of responsibility.
Hoth's highly mobile forces would move rapidly eastward to Voronezh and then turn southeast to follow the Don to Stalingrad.
The plan called for the 2nd to arrive just as the 4th had cleared the city, and Hoth was under orders to avoid any street-to-street fighting that might bog down their progress.
[e] Hoth's powerful armored forces moved forward with little delay and the only natural barrier before the city was the Devitsa River, an arm of the Don running through Semiluki, a short distance to the west.
