9 September The Volkhov Front offensive started on the morning of 27 August. The hidden buildup of forces allowed the Soviet forces to enjoy a significant superiority on the first day of the offensive in manpower, tanks and artillery and caught the German by surprise. The 8th Army had initial success advancing and scattering the first line of German defenses such as the 223rd Infantry Division, advancing on the first day at the location of the main attack. However initial attempts to expand on the flanks failed due to heavy German resistance. The German command reacted by redeploying the 5th Mountain and 28th Light Infantry (Jager) divisions from staging areas for Operation Nordlicht to meet the Soviet offensive. Lead elements from the 170th infantry Division, which had only arrived in Mga, have also joined the offensive. In addition Hitler diverted the 3rd Mountain division, which was being redeployed by sea to Finland, to Estonia instead. On 29 August the breach in the German defenses was up to deep. To sustain their advance towards Sinyavino, the Soviet forces started committing their second echelon divisions into combat. The German forces were further reinforced by the 12th Panzer and part of the 96th Infantry Divisions. Notably, this day saw the first combat deployment of the Tiger tank, as part of the 502nd Tank Battalion, which on 29 August had four Tigers. The attempt to counterattack with them failed as two of the tanks broke down almost immediately, and the third tank's engine overheated. During this first phase, aerial reinforcements were dispatched to Luftwaffenkommando Ost (Air Command East's) Luftflotte 1 (Air Fleet 1). The Oberkommando der Luftwaffe (High Command of the Air Force) sent several Jagdgeschwader (Fighter Wings) to assist German defences against intense Soviet air attacks. Elements of JG 54 and JG 77 were rushed to provide air superiority operations over the battle front. Despite being opposed by the Soviet 14th Air Army and outnumbered two to one, the Luftwaffe maintained air superiority. Luftflotte 1 destroyed 42 Soviet aircraft in large-scale air battles on the 1 and 2 September and relieved pressure on German ground forces. The German aerial activity was so effective, there was evidence some Soviet airmen's morale had broken down and they were not giving their best in combat. This prompted Joseph Stalin to threaten any pilot refusing to engage with the enemy a court-martial. However Soviet soldiers had to
