The Germans were well aware that breaking the blockade was very important for the Soviet side. However, due to the reverse at Stalingrad and the Soviet offensive at Velikiye Luki to the south of Leningrad, Army Group North was ordered to go on the defensive and was stripped of many troops. The 11th Army, which was to lead the assault on Leningrad in September 1942, and which had thwarted the last Soviet offensive, was transferred to Army Group Center in October. Nine other divisions were also reassigned to other sectors.
