DCI BRIEFING FOR
RIVERS SUBCOMMITTEE
SOUTH VIETNAM
I. You are no doubt aware that in South Vietnam
the Marines have moved stronger forces toward
the Demarcation Line between the North and
South, and that U. S. Army troops have been
deployed into the Da Nang area for the first
time to back up the Marines.
A. This is in answer to a number of indications
over the past five or six weeks that North
Vietnamese forces have been engaged in
an intensive build-up of troops and supplies
for offensive operations immediately south
of the so-called De-militarized Zone, in
Ouang Tri Province.

II. This build-up has been disrupted to some extent

A. For example, the US Marine operation
code-named PRAIRIE, which has been
under way in uang Tri Province since
early August, has killed more than 950
enemy troops by actual body count, and
taken several hundred prisoners.
1. There have also been two unusual
instances of group surrenders by
North Vietnamese troops--more than
60 in one case, and 35 in another.
B. US air operations in this area and over
the DMZ have caused numerous secondary
explosions and fires, indicating that
they are hitting supply and ammunition dumps.
C. Nevertheless, the enemy build-up is
continuing.

Against these Communist forces in Quang Tri
Province, at present we have six US Marine
Battalions in Operation PRAIRIE--about
8,100 men--and another six battalions of
South Vietnamese in the adjacent operation,
comprising about 2,250 troops.
1. It is to back up these committed
forces that the Marines have moved
more units toward the DMZ.
V. It is our present assessment of the Communist
build-up that they are not likely to attempt
a major offensive before the rainy season
sets in around the end of the month. Until
that time, US air and firepower superiority
should be able to successfully stave off any large
scale push.

A. It is important to remember, however, that the
Communists have gone for a considerable period
of time without any sort of a significant mili-

have indicated that the Communists are preparing
for just such a needed victory in the I Corps
area--preferably to come before the US elec-
tions in early November.
1. Moreover, past Communist practice has
shown that they are not adverse to throw-
ing large numbers of troops into a battle
if they believe they can achieve a signifi-
cent objective. In the present circum-
stances, the buildup that has already
taken place--clearly the most significant
current event in the war--gives rise to
the possibility that they may "go for
broke" in northern South Vietnam to gain
that elusive victory so necessary to their
morale.
B. In any case, it is estimated that Communist
forces in Quang Tri Province still retain the
capability to launch a multi-regimental of-
fensive in the coming weeks. Such a push
could be aimed at the series of towns along
Route 9 in central Quang Tri Province.

STATUS OF PETROLEUM IN DRV
1. DRV is believed to have a 70-100 days petroleum stockpile.
Recent deliveries by sea, and some transshipments through China, are
believed to have been adequate to meet consumption r_jquirements to dateatest -

another 20,000 tons capacity.
C. About 130 thousand 55 gallo~drums and an unknown
number of small military and industrial sites --
account for some 25 thousand tons capacity.
III. Since the bombing of petroleum facilities in Hanoi and
Haiphong in late June, no single petroleum storage area
can accept a fully loaded tanker carrying 10,000 tons.
A. Oil jetties at the Haiphong petroleum facilities still
are available, but the destruction of storage tanks
prevents use.
