body count."49

While Colonel Barrow's 1st and 3d Battalions were heavily engaged
to the north. Colonel Michael's 1st Battalion, 3d Marines, under Lieutenant
Colonel Twohey, continued to sweep south down Mutter Ridge, finding
numerous platoon- and company- sized bunker complexes. Each find led
to a more sophisticated one further south. The most significant finds
were an enemy supply battalion's storage area and what appeared to be
a regimental command post. The supply cache included more than 1,000
82mm mortar rounds and close to 15,000 AK-47 rounds. In the regimental

kitchens, several 60mm and 82mm mortar positions, and an extensive Chinese-built

and 2d Battalions, once they had completed their searches, to Thon Son

indicated he had entered the upper Cam Lo Valley, north of Thon Son
Lam and northwest of Dong Ha Mountain.50 With this information in hand.
General Davis decided to insert the 1st and 2d Battalions, 9th Marines
west of the 3d Battalion, 3d Marines positions, into a rugged, jungle-covered,
