By the end of August, Army Group South (B) had finally reached the Volga, north of Stalingrad. Another advance to the river south of the city followed, while the Soviets abandoned their Rossoshka position for the inner defensive ring west of Stalingrad. The wings of the 6th Army and the 4th Panzer Army met near Jablotchni along the Zaritza on 2 Sept. By 1 September, the Soviets could only reinforce and supply their forces in Stalingrad by perilous crossings of the Volga under constant bombardment by artillery and aircraft.
