| | On 17 May, 1942 the German 3rd Panzer Corps and XXXXIV Army Corps under the command of Fedor von Bock, supported by aircraft, arrived, enabling the Germans to launch Operation Fridericus, pushing back the Soviet Barvenkovo bridgehead to the south. On 18 May, Marshal Semyon Timoshenko requested permission to fall back, but Stalin rejected the request. On 19 May, Gen. Paulus launched a general offensive to the north as Bock's troops advanced in the south, thus attempting to surround the </ref>Soviets in the Izium salient. Realizing the risk of having entire armies surrounded, Stalin authorized the withdraw, but by that time the Soviet forces were already started to be closed in. On 20 May, the nearly surrounded Soviet forces mounted counteroffensives, but none of the attempts were successful in breaking through the German lines. The Soviets achieved some small victories on 21 and 22 May, but by 24 May, they were surrounded near Kharkov. | | On 17 May, 1942 the German 3rd Panzer Corps and XXXXIV Army Corps under the command of Fedor von Bock, supported by aircraft, arrived, enabling the Germans to launch Operation Fridericus, pushing back the Soviet Barvenkovo bridgehead to the south.
