By August 1941, the Hungarian mechanized corps was a key participant in the Battle of Uman. The "Rapid Corps" represented one half of a pincer which was enveloping the 6th Army and the 12th Army. The German 16th Panzer Division represented the other half of the pincer. On 3 August 1941, the pincer halves met and the 6th Army and the 12th Army were trapped. Over 100,000 Soviets were captured.
