In this episode, we are joined by world-renowned war historian Sir Antony Beevor. When someone says the Soviet Union, not the Western allies, defeated Nazism, they can point to this date, June 22, 1941, as a pivotal moment in that narrative. Eighty years ago today, the largest invasion in history began as more than three million German soldiers attacked the USSR in Operation Barbarossa. The battle caused a cataclysm; millions of people were brutally killed, including more than a million Soviet Jews. But the USSR survived, and Barbarossa's outcome helped shape our modern world.
