The Soviet command believed that German troops on the southern section of the Eastern Front were greatly weakened. There were no tank divisions left in the 1st Panzer Army in this sector. Only one tank battalion remained in the reserve 17th Panzer Division. So, the South-Western Front was supposed to strike three Guards Armies and to break the German defenses. After that, the Soviet tank formations were to enter the breakthrough. In the Stalino region they were to connect with the troops of the Southern Front and, thus, encircle German troops in Donbass. Compensating for the lack of tanks, German troops relied on their fortifications created since March 1943. In addition, Soviet intelligence seriously underestimated the strength of opposed infantry divisions. The Southwestern Front did not have a numerical superiority over the 1st Panzer Army, but it included many experienced Guards units. Indeed, the 8th Guards Army excelled during the defense of Stalingrad.
The Germans noticed Soviet preparations and on 14 July Hitler ordered the XXIV Panzer Corps from the reserve of Army Group South shifted back behind the 1st Panzer Army. The Soviet offensive began on July 17. The 1st and 8th Guards Armies managed to cross the Seversky Donets River, capture new bridgeheads on the right bank and advance to a depth up to 5 kilometers. However, the advance stopped there, because Soviet troops were unable to crack the defense system completely and so the tank units could not operate freely in a greater depth. The German command quickly used at first the reserves of the 1st Panzer Army and then the XXIV Panzer Corps. Attacks of the 3rd Guards Army in the auxiliary direction were completely unsuccessful. In the following days there was a fierce head-on battle. The German units launched counterattacks, trying to liquidate the Soviet bridgeheads. They did not achieve full success, but suppressed the Soviet troops and completely ruled out the possibility of an operational breakthrough. Both sides suffered serious losses. So, the 17th Panzer Division in a few days lost 91 officers and 2,446 soldiers, Generalleutnant Walter Schilling was killed. Opposing them, the 79th Guards Rifle Division lost 4,681 people and the division commander Batyuk died of a heart attack soon after the end of the operation. Military historianZiemke said about Izyum-Barvenkovo Offensive along with the Mius Offensive: "Those were small battles, like so many others quickly lost in the rush of greater events, but, nevertheless, enormously costly for both sides."
Results
Soviet troops failed to realize the plan of the offensive, the German troops in Donbas avoid encirclement and defeat. Soviet historiography claims that the operation shackled the German reserves necessary for the Battle of Kursk.
