After accepting new formations, the Army participated in the Novgorod-Luga Offensive Operation. After regrouping as part of the Leningrad Front (from 16 February), the Army made several attempts to encircle the German Army Group Narwa in the battle for Narva Bridgehead. After the failure to do so, the army took up defensive positions in late March to July. The Army participated in the Narva Offensive (July 1944) and the Battle of Tannenberg Line, 25 July to 10 August 1944. During September in cooperation with the 2nd Shock Army and the Baltic Fleet, the army conducted the Tallinn Offensive, as a result of which, mainland Estonia and the capital Tallinn were captured.
