Mark Bowden, author of 'Black Hawk Down,' talks about a turning point in the Vietnam War, the ferocious battle for the old imperial capital of Hue. He says "it was the bloodiest battle of its kind in the war." Communist forces took the city as part of the Tet Offensive of 1968, a coordinated set of attacks that soured many Americans on the conflict, and undermined the story US military leaders were telling the public and themselves about the war. Bowden interviewed dozens of participants in the battle as well as civilians who suffered terribly in the fighting. His new book is 'Hue 1968.'
