Then he was appointed Commander of the Bryansk Front (5 June – 10 October 1943), with which he participated in the Battle of Kursk. During the battle, the Bryansk Front was very successful in crushing German opposition, and was able to capture Oryol and Bryansk in August. He was promoted to Army General (26 August 1943). After the Battle of Kursk he was sent north, to command the 2nd Baltic Front (20 October 1943 – 23 April 1944). He was demoted to Colonel General (20 April 1944) because of the unsuccessful actions in the Baltic area, but the real reason seems to be his criticism on Nikolai Bulganin, who was Commissar at the front. Until the end of the war he was Chief of Staff of the Leningrad Front.
