INTELLIGENCE RELATED TO CROSS-BORDER OPERATIONS
]31a analysis of messages has revealed that Convmunist units continue
to experience difficulties as a result of Att.ied cross-border operations.
A 17 May message from a Subregion (SR) 2 subordinate stated
"For the past few days I have not been able to establish
contact. In accordance with the essential request, I em
saendi>ng Company 2 there to operate.' Therefore, you will
send a rncssage to regiment or battalion to send forces...
to carry two B-40's and enough amm lition to lost a long time.
The ration fund for uune is used up." -
This was also borne out by the statements of two prisoners, recently
captured near Chi Phu, They claimed that the. Headquarters of SR 3 and ita
Rear Services Section were forced to move deeper into Cambodia when Allied
forces destroyed their base area and storage `ft.c# l it Eec near Ba Thu.
Direction finding revealed that certain elements of COSVN in Kratie
?rovfnce was in a generally fluid situation. A COSW4 element reported to
a subordinate on IS llay that it was being ser'i.ously threatened by the enemy.
It informed all stations to monitor corm unicotions closely as it would retugfl
to the air when possible.
In Base Areas 350 and,351, documents captured following a Communist
attack on Fire Support Base (FSB) READ?' have .de:ntified the attacking uu,it
as the 28th VC Sapper Battalion, 5th VC Division. This unit was last
identified on 30 Mar 70 by documents captured northwest of Song Be. It
was believed at that time that the 28th Battalion was targeted against the
Song Be area, The new location northwest of Bu Dap indicates that Allied
cross-border operations have -forced the 5th Division to alter its planned
tactical activity in northern Phuoc Long Province.

The Sth Division Headquarters remains located In the vicinity of 'Bu
Trop, two of its major subordinates -- the 174th NVA and 275th VC Regiments --
however, have been conducting operations near' the town of :ratio..
In Base Area 704, during the continuing Operation CUU 'Long I, additional
evidence of enemy difficulties was revealed by Headquarters of Military Region
(M) 2 on 16 May. It advised Hanoi that it as under ground attack and about
to to ve. The next night, the watch facility of the MR advised all subordinates
that it would cease eonmiunications until the 21st.
Farther south near HUI 0 Mountain, the Poniard Element, Hq, let NVA
Division was fixed southwest of TAXED and about 20 miles north-northwest of
its previous location on HUI 0 as reflected Sri COMINNT on 16 May. This is
the deepest reported penetration into Cambodia by a 1st. Division'elemmut..
It indicates that subordinates of the let Division are attempting to avoid
contact with forces involved in operation CUtl Long It
In Cambodia, Korapong.Chara remains under government control following
an e?nesny raid, one. of the most concerted efforts against a Carrhbodian town.
The fighting, which began on 15 May, reached ,a peak the following day when
an estimated two enemy' battalions penetrated ompong shags from the northwest.
They occupied a portion of the cosh, but a combined Cambodian air and ground
assault forced their withdrawal. Three YANK battalions from. Phnom Penh
comprised the relief force.. ' The enemy has apparently withdrawn to towre
just west of l;.ompong Cham. A FANK.battalion i.s on the east bank of the
McRong River near Tonto Bet, but the 272d VC Regiment, believed located some
12 miles southeast of Tonle Bet, continues to pose a serious threat.
On the political side, the Cuban Governricnt has asked that representatives
of the Lon Nol Government to depart Cuba irromddiately. They were ordered to
leave behind all except. their. personal belonZ$ings. everything in the embassy
