Too many specific years in the twentieth century were said to be ‘pivotal’, but 1968 was clearly a standout. In the United States, Martin Luther King and Bobby Kennedy were assassinated; there were student protests in Paris; and Russian tanks signalled the end of the ‘Prague Spring’. In January 1968, on the other side of the world, in an area once known as French Indochina, the army of the National Liberation Front (the Vietcong) invaded the imperial city, Hué, and all other major cities in South Vietnam. This was the infamous Tet Offensive.
