World War II was marked by its epic battles, which decided the fate of nations and changed the course of history. From Germany's Blitzkrieg attacks on Poland that launched the European campaign to the Allied invasion of Berlin that signaled its violent end, we bring these seminal conflicts to life through never-before-seen colorized combat footage. This six-part series puts you in the center of the action through rarely scene films from the frontline plus personal memoirs and oral histories from both sides of the battle lines.
