Mobile Riverine Force (MRF) and elements of the Army of the Republic of Vietnam from 12 September to 5 October 1967 in an attempt to shut down Viet Cong (VC) strongholds in the Mekong Delta.

Brigadier General Nguyen Manh Thanh, commander of the ARVN 7th Division, was given information that the VC 263rd Main Force Battalion had been in the vicinity of Cam Son and Ban Long in the past 10–14 days.

The 3rd and 5th Battalions of the 60th Infantry Regiment, under the control of the 2nd Brigade, used helicopter and overland movement to access the major east-west forested portion of the Ban Long area.

Under the pressure of the American infantry advance and supporting fire, the VC attempted to evade to the north and northwest, exposing themselves along thinly vegetated rice paddy dikes.

The 5/60th Infantry, northwest of the 3rd Battalion, engaged a platoon of the enemy; fire from M113 armored personnel carriers and mortars killed or dispersed the VC.

[1]: 129 After consulting with General William B. Fulton, Colonel David concluded that if an operation was launched around Cam Son on 15 September, the Americans might be able to find the 514th Local Force Battalion.

The plan was to attack the area in central Cam Son; previous operations had yielded evidence that it was the location of the VC's heaviest fortifications.

In order to not alert the VC and give them time to escape, David decided to withhold preparatory and reconnaissance fire until the American assault craft passed a wide curve in the Rach Ba Rai referred to as "Snoopy's Nose" (10°19′23″N 106°05′20″E / 10.323°N 106.089°E / 10.323; 106.089).

Finally, to provide a higher degree of flexibility in case the VC was found, the 2/60th Infantry, 3rd Brigade, was designated a reserve force by the 9th Division.

By 07:30 the lead boats were nearing Beach White Two where a company of Lt. Col. Mercer M. Doty's 3/60th Infantry, was to land when the flotilla came under heavy rocket, automatic, and small arms fire from both sides of the stream (10°22′34″N 106°05′17″E / 10.376°N 106.088°E / 10.376; 106.088).

To act contrary to this procedure would constitute an action outside the "limits permitted by accepted tactical practices" of the Navy task force.

[1]: 132 The boat captain who passed the minesweepers and landed his ATC at White Beach One was thought to have pressed on by the fact that the infantry company commander was on board.

One ARVN battalion was landed by helicopter at approximately 16:00, northwest of the 3/60th Infantry, and prepared to set up a position along the west bank of the Rach Ba Rai.
