The Second World War arrives through four American towns: Mobile, Alabama; Waterbury, Connecticut; Sacramento, California; and Luverne, Minnesota. Ken Burns and Lynn Novick built this seven-part series entirely on the memories of people who lived it, deliberately leaving out historians and outside experts so the war stays at eye level, told by veterans, factory workers, and the families waiting at home. The first episode, A Necessary War, follows the country from an uneasy peace into Pearl Harbor; later parts track the industrial conversion that armed the war effort, the invasion of Europe, the grinding losses at the Battle of the Bulge, and the separate, brutal campaign across the Pacific. The final episode covers the German surrender and the atomic bombings that ended the fighting with Japan. Archival footage, home movies, letters, and newspaper clippings carry the visual record, but it is the on-camera testimony, delivered decades later by people recalling specific streets, ships, and losses, that anchors each hour.
