10. The Forced March from Stalingrad (1943)
After the catastrophic German surrender at Stalingrad, tens of thousands of exhausted POWs were driven on grueling marches eastward through the Russian winter. Exposed to relentless cold, with little food or shelter, many prisoners died from exposure, starvation, or disease before ever reaching the prison camps. The ordeal was so severe that only a fraction of those captured survived to return home. HistoryNet
