Serving as deputy commander-in-chief of the Steppe Front for cavalry from July, Konstantinov took command of the 7th Guards Cavalry Corps in October. He led the corps for the rest of the war, a period in which it fought as part of the 65th, 61st, 47th, and 69th Armies of the Belorussian, 1st and 2nd Belorussian Fronts in the Gomel–Rechitsa, Polesskoe, Belorussian, Vistula–Oder, East Pomeranian, and Berlin Offensives. He was promoted to lieutenant general on 26 July 1944. For "courage, heroism, and timely fulfillment of front objectives" during the capture of Łódź and the defeat of German troops in the area of Radom, Tomaszów, and Łódź in the January 1945 Vistula–Oder Offensive, Konstantinov received the title Hero of the Soviet Union and was awarded the Order of Lenin on 6 April 1945.
