Armed with Lysenko's report of German tanks just outside Radekhiv, Maj. Gen. Sergei Y. Ogurtsov of 10th Tank Division hoped to fling his entire formation at them in a mass attack. One of his two tank regiments did not reach its assembly area on time, held up by German air attacks, and Ogurtsov decided not to wait for it and expose the rest of his division to the same treatment. Tenth Tank Division had undergone extensive large-unit training for just such an opportunity, but their commander eschewed maneuver and flung them into a brutal frontal assault.

The Soviets had numbers on their side and a marked superiority in armor quality. But they attacked in waves, aiming their tanks directly into the teeth of German defenses including 88mm anti-aircraft guns deployed in a ground role. The attack broke up and the Soviets left dozens of destroyed tanks behind. Exact losses are hard to determine, as it's unclear if Lysenko's task force from 32nd Tank Division was also present and the Germans may have included tanks destroyed in the morning battle in their claims. Whatever the exact result, 10th Tank Division had suffered a serious setback, made worse over the next few days as higher commands sent contradictory orders causing the division to wander aimlessly across the battlefield constantly losing tanks to mechanical breakdowns and air attacks.
