On January 31, 1968 according to the lunar calendar, the Year of the Monkey begins. And perfectly embodying the cunning and genius attributed in the Far East to this symbolic animal, General Võ Nguyên Giáp prepared a terrible surprise for the American, Australian and South Vietnamese soldiers: instead of the usual truce for the Tet anniversary, little after midnight a massive offensive starts which sees the regular troops from the North invading the regions close to the border. For months there was bitter fighting, in Hue and Khe Sanh in particular, marking a turning point in the Vietnam conflict.
