 Correctly anticipating that the PAVN's Quảng Nam campaign had only begun and that more forces would be required to deal with it, I Corps commander General Ngô Quang Trưởng on 19 July ordered the 12th Ranger Group to move from Quảng Ngãi to Quảng Nam.The 37th Ranger Battalion, already in Da Nang for rest and retraining, moved to Hieu Duc District on 20 July.That day, the 6th Infantry, 2nd Division, began relieving the other two battalions of the 12th Ranger Group in Đức Phổ and Mộ Đức Districts in Quảng Ngãi Province, and the 12th began to move north.
