time, which is that if the attack had continued aggressively and without delay, the Soviets might have been successful. However, subsequent events seem to vindicate Kirponos's position, which was that the attack was premature and would destabilize the integrity of the entire front. Shortly after the Soviet counter-attack was routed, Marshal Semyon Budyonny was given overall command of the combined Southwestern and Southern Front. Disaster unfolded at the Battle of Uman and 100,000 Soviet soldiers were killed or captured and another 100,000 wounded when three Red Army formations - the 26th, 12th and 18th armies - were encircled after Army Group South renewed its attack by pivoting south from the positions it had achieved during the Battle of Dubno—an outcome that Kirponos had foreshadowed in his arguments with Zhukov about the wisdom of the counter-attack at Dubno. The confrontation between Kirponos and Zhukov led Zhukov to tell the Southwestern Front political officer, Nikita Khrushchev, "I am afraid your commander (Kirponos) here is pretty weak", a charge that Kirponos would never be able to answer, since he died in the battle of Kiev after it was surrounded. Summary The battle between Panzer Group 1 and the Soviet mechanized corps was the fiercest of the whole invasion, lasting four full days. The Soviets fought furiously, and crews of German tank and anti-tank guns found to their horror that the new Soviet T-34 tanks were almost immune to their weapons. The new KV-1 and KV-2 heavy tanks were impervious to virtually all German anti-tank weapons, but the Red Army's logistics had completely broken down due to Luftwaffe attacks. The German Kampfgeschwader bomber wings, namely KG 51, KG 54, and KG 55, contributed a series of heavy low-level attacks against Soviet ground targets. The headquarters of the Soviet 15th Mechanised Corps was destroyed, and its commander, General-Major Ignat Karpezo, was wounded. The Luftwaffe destroyed some 201 Soviet tanks in this area. The five Red Army corps were mishandled while being concentrated into large powerful groups. The German troops sought to isolate individual units and destroy them. Meanwhile, the Luftwaffe ranging over the battlefields was able to separate the supporting infantry and deny them resupply of fuel and ammunition. Ultimately due to lack of adequate planning and overall coordination, the Soviet counter-attack failed to meet at Dubno. After the battle Panzer Group 1 took a severe battering in the battles around Dubno, losing many of
