was frequently cut by regular German and Finnish air strikes. Despite of several German requests Mannerheim decided that Finnish forces would not attack Leningrad. Soviet forces launched several offensives in the region in 1942, but these failed to lift the siege. The Lyuban Offensive Operation resulted in the encirclement and destruction of most of the Soviet 2nd Shock Army. In this situation, Govorov's background as an artilleryman was considered most valuable, since the city was under constant shelling, and one of Govorov's tasks was to launch an artillery counter-offensive against the German guns. As soon as he became the commander of the Leningrad Front in July 1942, Govorov mounted local attacks in several sectors of the front, while preparing a much larger offensive. Together with the Volkhov Front, the Leningrad Front would break the blockade of the city by eliminating the German positions south of Ladoga Lake, where only separated the Leningrad and Volkhov Fronts. This position was called "the bottleneck". 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 arrived from Sevastopol, which the German forces had captured in July 1942. Both sides were unaware of the other's preparations. As a result, the Soviet Sinyavino Offensive failed and the 2nd Shock army was decimated for the second time in a year, but the German forces suffered heavy casualties and canceled Operation Northern Light. In late November 1942, Govorov began planning the next operation to break the blockade of Leningrad. In December, the plan was approved by the Stavka and received the codename Operation Iskra (Spark). Operation Iskra began on 13 January 1943, and on 18 January Soviet forces linked up, breaking the blockade. By 22 January the front line stabilized. The operation successfully opened a land corridor 8–10 km wide to the city. A railroad was swiftly built through the corridor that allowed far more supplies to reach the city than the "Road of Life", eliminating the possibility of the capture of the city and a German-Finnish link up. Govorov was promoted to Colonel General on 15 January and was awarded the Order of Suvorov 1st Class on 28 January. The Leningrad and Volkhov Fronts tried to follow up their success with a much more ambitious offensive operation named Operation Polyarnaya Zvezda (Polar Star). This operation had the aim of decisively
