In August 1942, the Blue Division was transferred north to the southeastern flank of the siege of Leningrad, just south of the river Neva near Pushkin, Kolpino and Krasny Bor in the Izhora River area. After the collapse of the German southern front following the Battle of Stalingrad, more German troops were deployed southwards. By this time, General Emilio Esteban Infantes had taken command. The Blue Division faced a major Soviet attempt to break the siege of Leningrad in February 1943, when the Soviet 55th Army, reinvigorated after the victory at Stalingrad, attacked the Spanish positions at the Battle of Krasny Bor, near the main Moscow-Leningrad road. Despite very heavy casualties, the Spaniards were able to hold their ground against a Soviet force seven times larger and supported by tanks. The assault was contained and the siege of Leningrad was maintained for a further year. The division remained on the Leningrad front where it continued to suffer heavy casualties due to weather and to enemy action.
