Objective
To fight the 18th Regiment in the Binh Dinh Province, Technically an extension of Operation Thayer I. Search and destroyr operation to clear area around Phu Cat Mountain.
Description
This operation developed from Operation Thayer I when the 1st Cavalry pushed the PAVN forces back from the Kim son Valley to the coastal plain. While the ROK Capital Division and ARVN Division set up in blocking positions, the 1st Squadron, 9th Cavalry reconnaissance team uncovered entrenched PAVN forces. More 1st Cavalry Brigades entered the conflict and support came from artillery, helicopter gunships, and naval gunfire. The most intense fighting of the conflict occurred at Hoa Hoi, where the 7th and 8th battalions of the 18th PAVN Regiment were cornered. Though very few civilians died, 10,000 became refugees. Even though IRVING offered a great display of airmobility and exemplified a combined forces operation, the PAVN were soon back in Kim Son and Suoi Ca. There were 1,000 PAVN POWs.
