At a total cost of more than 3.1 million lives, the Vietnam conflict is, to date, America's longest and most controversial war. It also marked the first time TV journalists ventured out to the frontlines to bring the spectacle of combat into American living rooms. Across the nation, Americans watched, captivated by the surprise Tet Offensive, the slow-motion tragedy of the Battle of Khe Sanh, and the courage and skill of the American soldiers. Now The History Channel presents an expansive 2-disc set that profiles the decision makers and chronicles the key events in the Vietnam War, from the advisor's arrival in 1959 to the airlift from the roof of the American embassy in 1975. Archival footage and interviews with historians and veterans reveal the military and political strategies in play, and CBS News archives take viewers to the frontlines to witness the daily struggles of American servicemen and women. - Container.
