The biggest difference from the earlier Sinyavino Offensive was the location of the main attack. In September 1942 the Soviet forces were attacking south of the town of Siniavino, which allowed them to potentially encircle several German divisions, but also left the army open to flanking attacks from the north, and it was this which ultimately caused the offensive to fail. In January 1943 the offensive was conducted north of Siniavino, closer to the Ladoga Lake shore, which removed the threat of flanking attacks and increased the probability of success, but forced the Soviets to abandon the idea of encircling most of the German forces in the "bottleneck".
