After rebuilding the division held the Army's bridgehead over the Volkhov during 1943, and finally advanced during the Leningrad–Novgorod Offensive in January 1944, taking part in the assault that liberated Novgorod.

During the spring the division saw heavy fighting in the battles for Narva before moving south for the summer offensive into the Baltic states.

The division ended the war in Latvia, helping to contain and reduce the German forces trapped in the Courland Pocket, and was disbanded later in 1945.

The 377th began forming in August 1941 in the Urals Military District[1] at Chebarkul in the Chelyabinsk Oblast, based on the first wartime shtat (table of organization and equipment) for rifle divisions.

Volkhov Front, including 59th Army, began the offensive on Lyuban, which was intended to break the German siege of Leningrad, on the morning of 6 January, but the Soviet forces were far from fully prepared and by the end of the day this initial assault expired in the face of heavy resistance.

Soon, General N. Voronov, the chief of the Red Army's Artillery was sent to Malaya Vishera with several railway cars containing the missing equipment.

On 17 January, 2nd Shock resumed its attack, supported by more than 1,500 aircraft sorties, and finally penetrated the Germans' first defensive positions on the west bank of the Volkhov, advanced 5 – 10 km and created conditions that Front commander Army Gen. K. A. Meretskov considered favorable for developing success.

Kovalchuk was briefly replaced by Col. Leonid Gavrilovich Sergeev on 2 January 1943, but returned to command on 2 February, and was promoted to the rank of major general on 18 May.

On 28 August General Kovalchuk, who was already serving as chief of staff of 59th Army, handed his command to Col. Semyon Sergeevich Safronov.

Over the next four days the Army made a slow but inexorable advance north and south of the city, threatening to envelop the German forces defending it.

Korovnikov resumed his offensive on 21 January and provided significant engineer support to cross the roadless and heavily forested swampland spanning the entire region east of Luga.

The troops who participated in the liberation of Valga, by the order of the Supreme High Command of September 19, 1944, and a commendation in Moscow, are given a salute of 12 artillery salvoes from 124 guns.

[14] The division played a major role in the liberation of Riga, and received the award of the Order of the Red Banner on 31 October.
