Whether by accident or design, the first wave of attacks began shortly after midnight on 30 January as all five provincial capitals in II Corps and Da Nang, in I Corps, were attacked. Nha Trang, headquarters of the U.S. I Field Force, was the first to be hit, followed shortly by Ban Mê Thuột, Kon Tum, Hội An, Tuy Hòa, Da Nang, Qui Nhơn, and Pleiku. During all of these operations, the PAVN/VC followed a similar pattern: mortar or rocket attacks were closely followed by massed ground assaults conducted by battalion-strength elements of the VC, sometimes supported by PAVN regulars. These forces would join with local cadres who served as guides to lead the regulars to the most senior South Vietnamese headquarters and the radio station. The operations, however, were not well coordinated at the local level. By daylight, almost all communist forces had been driven from their objectives. General Phillip B. Davidson, the new MACV chief of intelligence, notified Westmoreland that "This is going to happen in the rest of the country tonight and tomorrow morning." All U.S. forces were placed on maximum alert and similar orders were issued to all ARVN units. The allies, however, still responded without any real sense of urgency. Orders cancelling leaves either came too late or were disregarded.
