Ivan Mikhailovich Chistyakov was a Soviet Army colonel general and a Hero of the Soviet Union.

Operation Bagration was the codename for the 1944 Soviet Byelorussian strategic offensive operation, a military campaign fought between 22 June and 19 August 1944 in Soviet Byelorussia in the Eastern Front of World War II, just over two weeks after the start of Operation Overlord in the west, causing Nazi Germany to have to fight on two major fronts at the same time. The Soviet Union destroyed 28 of 34 divisions of Army Group Centre and completely shattered the German front line. It was the biggest defeat in German military history, with around 450,000 German casualties, while 300,000 other German soldiers were cut off in the Courland Pocket.
