Postcard from Hue - in search of Tet 1968

We visit Hue Citadel in central Vietnam just before the fiftieth anniversary of the Tet Offensive and the Battle of Hue, looking for traces of the battle and the city's account of it. The Battle of Hue was one of the longest, bloodiest and most important of the Vietnam War. But a visitor to Hue could pass through the city and not even know it occurred.
