SUBJECT: TRI TAM BATTLE AND SITUATION IN TAY NINH CITY
REF: BIEN HOA 142
1. THE MR3 COMMANDER AND HIS 2 DEPUTIES WERE TRAVELLING MOST
OF THE DAY MAR 11 AND REFTEL WAS BASED ON INFORMATION FROM
LOWER LEVEL SOURCES AT MR3 HQ. DEPT CMDR, MG HIEU, AFTER RETURNING FROM EASTERN TAY NINH AT THE END OF THE DAY, REVIEWED THE TRI TAM AND TAY NINH PROVINCE SITUATION WITH ME OVER COFFEE AT 2100 HOURS MAR 11. HE GAVE A CONSIDERABLY MORE FAVORABLE ACCOUNT OF THE SITUATION THAN THAT SET FORTH REFTEL.
2. ACCORDING TO HIEU, THE NVA/VC BROKE OFF THE ATTACK AT TRI
TAM AT THE END OF THE DAY AFTER THE ATTACKING 272ND NVA REGT
HAD FAILED TO BREACH THE DEFENSES AND SAPPERS WHO HAD PENETRATED TO THE MARKET (HE SAID TANKS NEVER REACHED THE MARKET AREA) WERE THROWN BACK. THE SITUATION WAS QUIET AT 2030 HOURS. MOST OF THE ARVN THIRD ARMORED BRIGADE WAS DEPLOYED FROM BINH DUONG PROVINCE DURING THE DAY AND BY LATE AFTERNOON WAS IN PLACE ON ROUTE 26 IN EASTERN TAY NINH PROVINCE AROUND AND NORTH OF KHIEM HANH. ITS MISSION IS BOTH TO PUSH TO THE RELIEF OF TRI TAM AND TO COUNTER ANY HEAVY NVA/VC THRUST IN WESTERN TAY NINH PROVINCE. THE 3RD ARMORED COMMANDER, BG KHOI, HAS NOW BEEN GIVEN OPCON OF FORCES IN EASTERN TAY NINH AND TRI TAM. MR3 HAS ESTABLISHED A FORWARD CP AT GO DAU HA.
3. ON ROUTE 22, MEANWHILE, THE NVA/VC HAD BEEN PUSHED OUT OF 2
OF THE 3 POINTS OF INTERDICTION WITH SOME PROSPECT FOR RE-OPENING THE ROAD WITHIN A DAY OR TWO. AT THE SAME TIME, ACCORDING TO HIEU, MR3 HQ SEES NO SIGN OF ANY NEW MOVEMENT OF MAJOR NVA/VC FORCES IN A MENACING WAY NORTH OR WEST OF TAY NINH CITY.
4. HIEU SAID THE 3RD ARMORED BRIGADE HAD BEEN MOVED TO EASTERN
TAY NINH IN THE BELIEF THAT THE TRI TAM ATTACK SIGNALLED AN
INTENT ON THE PART OF THE OTHER SIDE TO HIT THAT AREA THEN
SQUEEZE TAY NINH CITY RATHER THAN ASSAULT THE CITY DIRECTLY. HE
SAID GEN TOAN HOPES HE HAS NOT OVERREACTED BY BRINGING MORE
FORCES TO BEAR IN THAT AREA THEN ARE REQUIRED. TOAN RECOGNIZES
THE POSSIBILITY THAT CURRENT ATTACKS IN THE TAY NINH AREA MAY
ONLY BE LIGHT AND DIVERSIONARY TO SUPPORT THE HEAVY ACTION IN
MR II, WITH HEAVIER ATTACKS IN MR III TO COME LATER. HIEU THOUGHT
THAT ROCKETING OF BIEN HOA WOULD BE ONE IMPORTANT CLUE. FURTHER HEAVY ROCKET ATTACKS NOW WOULD SHOW AN INTENT TO NEUTRALIZE VNAF FOR IMMEDIATE NVA/VC ATTACKS WHILE A BREAK, OR SPORADIC LIGHT ATTACKS, WOULD INDICATE POSTPONEMENT OF HEAVY ATTACKS IN MR III.
5. LATEST WORD REGARDING TRI TAM AT 0730 HOURS MAR 12 FROM G-3
SOURCES AT MR3 HQ IS THAT THE NVA/VC RENEWED THE ATTACK WITH
INFANTRY AND ARMOR AT 0200 HOURS AND FIGHTING CONTINUES.
6. MG HIEU SHOULD NOT CITED AS SOURCE IN ANY DISCUSSION OF THIS
MESSAGE'S CONTENTS WITH GVN OFFICIALS.
