Sinyavino offensive (1942)
The Sinyavino offensive (or third Sinyavino offensive) was an operation planned by the Soviet Union in the summer of 1942 with the aim of breaking the siege of Leningrad, which had begun the previous summer, and establish a reliable supply line to Leningrad. At the same time, German forces were planning Operation Northern Light () to capture the city and link up with Finnish forces. To achieve that heavy reinforcements were arriving from Sevastopol, which the German forces captured in July 1942. Both sides were unaware of the other's preparations, and this made the battle unfold in an unanticipated manner for both sides.
