Going into the Go Noi

By the beginning of May 1968, both the Marines at
Da Nang and the Communist forces in Quang Nam were in the midst of preparations
to launch offensive operations against one another. While during April
the enemy in Quang Nam had largely confined its activities to guerrilla
activities, the increased number of reconnaissance Stingray sightings
indicated that Communist regulars were reinfiltrating their old positions.
The Marine command was especially concerned about the Go Noi Island
sector, about 25 kilometers south of Da Nang, outlined by the confluence
of the Ky Lam, Thu Bon, Ba Ren, and Chiem Son Rivers.

In the Go Noi, the 3d Battalion, 7th Marines in April
had conducted Operation Jasper Square* in the western sector with relatively
limited contact. Nevertheless, the Communists had controlled the area
for years. With the continued existence of both a Communist political
and military command infrastructure there, the local populace maintained
a strong Viet Cong orientation, making the island a relatively 'safe
haven' for both NVA and VC military units. III MAF knew Go Noi was home
to three local Viet Cong units, the R-20 Battalion, V-25
, and T-3 Sapper Battalion, as well as Group
, the headquarters for the enemy's operations in Quang Nam Province.
It also suspected that elements of the 2d NVA Division were
trying to reenter the sector.1

In early May, Major General Donn J. Robertson, the
1st Marine Division commander, ordered the 7th Marines into the Go Noi
to forestall the NVA from staging a new offensive. On 4 May at 0500,
Lieutenant Colonel Charles E. Mueller's 2d Battalion, 7th Marines launched
a two-company 'No Name Operation' into the Go Noi. Crossing Liberty
Bridge at 0500, Companies E and G, supported by a platoon of tanks,
attacked eastward towards the main north-south railroad tracks. On the
first day of the operation, the Marines evacuated some 220 civilians,
mostly old men, women, and children, out of the Go Noi to the district
capital of Dai Loc.2

In the first phase of the operation, which soon became
Operation Allen Brook,** the battalion encountered light although persistent
resistance from enemy local force and guerrilla units. For the next
few days, the 2d Battalion attacked to the east towards the main north-south
railroad tracks experiencing increasing but still relatively scattered
opposition to their advance. Although the terrain was flat with relatively
clear fields of fire, the local units were familiar with the locale
and took full advantage of the advantages offered by the fortified hamlets
that dotted the Go Noi. Surrounded and interlaced by dense hedges, these
hamlets were connected one to another by a series of trenches and tunnels
which provided 'excellent cover and concealment' for their defenders.3

While Company A, 1st Battalion, 7th Marines relieved
Company G on 7 May, Colonel Reverdy M. Hall, the 7th Marines' commander,
also reinforced the 2d Battalion on the same day with Company K from
the 3d Battalion. Through 8 May, the Marine companies accounted for
some 88 enemy troops at a cost of 9 Marines killed and 57 wounded. On
the 9th, about 1820, the sweep forces just west of the railroad tracks
came under heavy small arms and machine gun fire as well as a mortar
salvo outside of the hamlet of Xuan Dai (2). Taking casualties of l
dead and 11 wounded, the infantry pulled back and called for artillery
support and airstrikes. After the last air mission, the Marine companies
clambered over the tracks which fronted the hamlet on the west and pushed
into Xuan Dai (2). Thirty minutes after the initial action, the Marines
secured the hamlet. As a result of this action, the Marine battalion
reported 80 enemy killed. A Stingray patrol about 1900 observed some
200 enemy troops moving to the southwest of Xuan Dai and called in

** Lieutenant Colonel Mueller recalled that the operation
'very quickly became operation Allen Brook' in that his two other companies
'and a myriad of support was attached to my battalion.' A 'No Name'
operation usually involved two companies with minimum support. The concept
was to 'reinforce quickly when significant contact was made.' LtCol
