Karelian Front
On 23 August 1941, the Northern Front was split into the Karelian Front and the Leningrad Front, commanded by Valerian Frolov and Popov, respectively. Frolov remained in command of the Karelian Front until 1 September, when he was replaced by Roman Panin on his promotion. During the first weeks, the Axis had numerical superiority, as the Soviets only had 150,000 men stationed north of Lake Ladoga along the border. The Axis powers also possessed air superiority, as Soviet Karelia was only protected by the 1st and 55th Mixed Air Divisions, with 273 serviceable aircraft of obsolescent types.
