The PAVN/NLF attacks were speedily and bloodily repulsed in virtually all areas except Saigon, where the fighting lasted for three days, and in the old imperial capital of Huế, where it continued for a month. During the occupation of the historic city, 2,800 South Vietnamese were murdered by the NLF in the single worst massacre of the conflict. The hoped-for uprising never took place; indeed, the offensive drove some previously apathetic South Vietnamese to fight for the government. Another surprise for the communists was that the ARVN did not collapse under the onslaught, instead turning in a performance that pleased even its American patrons.
