The second Smolensk operation was a Soviet strategic offensive operation conducted by the Red Army as part of the Summer-Autumn Campaign of 1943. Staged almost simultaneously with the Lower Dnieper Offensive, the offensive lasted two months and was led by General Andrei Yeremenko, commanding the Kalinin Front, and Vasily Sokolovsky, commanding the Western Front. Its goal was to clear the German presence from the Smolensk and Bryansk regions. Smolensk had been under German occupation since the first Battle of Smolensk in 1941.
