1st PROVISIONAL MARINE BRIGADE ATTACHED TO 24th INF DIV.
SHOWING MARINE & ARMY ATTACKS & N.K. POSITIONS, COUNTERATTACK, & WITHDRAWALS
Marine air and artillery were to pound the ridge on 17 August from 0725 to H-hour, 0800, after which MAG-33 would strafe the hill to cover the advancing infantrymen.[297] Brigade artillery fired its preparation as planned; but due either to the hasty registration of the previous day or to error on the part of observers, the shelling was not effective against the enemy on Objective One. It was so inacurrate, in fact, that many officers of 2/5 thought there had been no preparation at all.[298] To make matters worse, air attacks scheduled to begin at 0725 did not materialize until 0740; and the 18 Corsairs assigned to the job had time for only one strike before H-hour.[299]

The two rifle companies of the 2d Battalion jumped off abreast at 0800. On the right was Captain Zimmer’s Company D, emerging into the open from the road cut between Hill 125 and Observation Hill.[300]

Zimmer ordered the 2d Platoon into reserve on the southern spur of Hill 125 and established his OP there. The 3d Platoon, commanded by Second Lieutenant Michael J. Shinka, stepped from the road bend below the spur into the rice paddy. Advancing behind this unit were the 1st Platoon and a rocket section, the latter stopping in positions along the road bend to protect the MSR.
