The following morning as the unit was returning along the same route a command detonated mine exploded wounding 5 Marines. The NVA then opened fire with small arms and mortar fire and attacked the armored vehicles with RPGs. The NVA attempted to hug the US column negating the use of air support and the column broke up into several separate firefights. The isolated Marine Companies set up night defensive positions and were eventually relieved by 3/4 Marines on the morning of 30 July.

As the units advanced through the hedgerows the companies came under sniper, mortar and then heavy artillery fire. In the 3 pronged attack Fox Company was hit first and the hardest. Echo Company coming down from the Trace also ran into major problems. Golf Company, originally the blocking force for the other two companies was now attempted to outflank the NVA positions, but they were caught in an open rice paddy and was forced back by small arms and mortar fire.
