1. CAUSES
Two conflicting views on why the Offensive happened:
a. Opportunity
• North Vietnamese saw war = stalemate by 1967: US bombing had failed, US public support ↓
• Hoped S. Vietnamese people would rise up, ARVN collapse, & that US would realise it couldn’t win → withdraw
• Soldiers told by Party propaganda: great victory close
b. Despair
• By 1967: S. Vietnam’s govt was stabilising, US bombing + Search & Destroy tactics were working
• Ho Chi Minh, Giap & moderates began pushing for peace negotiations
• Southern-firsters carried out Anti-Party purge, took over Politburo, demanded full-scale attack
2. WHY THE PAVN-VC DID WELL INITIALLY
a. Surprise: launched during Tet (Vietnamese New Year); 36-hour CEASEFIRE meant half ARVN on leave
b. Long-term planning: PAVN-VC had built up troops & intelligence since summer 1967
c. US errors: senior command knew about build-up but didn’t inform officers/govt
d. PAVN-VC = battle-hardened vs inexperienced US ‘cherries’
3. EVENTS
a. 31 Jan 1968: 80,000 PAVN-VC attacked 100 towns/cities → 21 weeks of fighting
b. Saigon
• 35 VC battalions attacked:
◦ targets incl. US HQ at LONG BINH;
◦ suicide squad seized US EMBASSY (6 hrs);
◦ PAVN-VC cleared only by April
c. ‘Mini-Tet’ (May) & Phase III (Aug): 2 further PAVN-VC offensives
d. Khe Sanh, 21 Jan–5 Jul 1968
(i) CAUSES/CONTEXT:
• Khe Sanh = key part of McNamara Line, close to Laos/Ho Chi Minh Trail, isolated → vulnerable
• Intended to distract US from Tet areas (or vice versa – US unclear at time)
(ii) EVENTS:
• 21 Jan: 20k-40k PAVN besieged US Marines
• Relief reached base 8 Apr; fighting continued until July
• US finally withdrew; base closed in July
(iii) CONSEQUENCES:
• PAVN victory – McNamara Line ABANDONED
e. Hue, 31 Jan–25 Feb 1968
(i) CAUSES/CONTEXT:
• Target city: important port, Highway 1 ran through it, ex-capital, centre of Buddhist protest in 1963
• Many ARVN on Tet leave
(ii) EVENTS:
• VC sappers opened city gate; 11k PAVN-VC took Hue incl. ancient citadel
• US/ARVN retook city by 25 Feb – heavy urban combat
• PAVN-VC EXECUTED c.2,800 civilians – incl. officials, police, doctors, monks
(iii) CONSEQUENCES:
• 75% of homes wrecked, 116k civilians homeless
• US govt used civilian massacre as propaganda to justify war
e. My Lai, 16 Mar 1968
(i) CAUSES/CONTEXT:
• 3 months into Tet; Feb operation to clear VC had failed
• US troops = young, scared, demoralised; drug use, fragging, indiscipline common
• Told area = stronghold of VC’s Local Force 48TH BATTALION
• Told that civilians gone → “They’re all VC, now go get them”
(ii) EVENTS:
• C Company (Capt. Medina) entered My Lai 4
• 1st Platoon (Lt. CALLEY) found no VC, no resistance – murdered 347 civilians incl. women & babies
• Mass rapes, grenades, water supply polluted, executions incl. infants
• Helicopter pilot Hugh Thompson tried to stop killings
• B Company killed 60-155 civilians at nearby My Khe 4
(iii) CONSEQUENCES:
• Initially covered up – official report claimed 90 VC killed, 1 US wounded (later found to have been self-inflicted)
• When revealed 18 months later: few consequences – survivors scattered, only Calley convicted (of 22 murders), sentenced to life imprisonment 1971
• US public reaction mixed – many defended Calley; Nixon cut sentence to house arrest → freed 1975
• Long term: ruined US image – smeared as ‘baby-killers’, anti-war movement ↑, US motives questioned
4. WHY THE PAVN-VC WERE DEFEATED
a. Westmoreland had repositioned 15 US battalions to Saigon = “most CRITICAL TACTICAL DECISION of the war”
b. US/ARVN = too strong in manpower & firepower
c. Offensive = overambitious: forced VC into open battle → couldn’t hold territory
• North Vietnamese Politburo member Tran Van Tra (1983): overestimated own strength, underestimated US
d. S. Vietnamese did not rise up, ARVN fought effectively
5. DISASTROUS CONSEQUENCES
“Only military action that BOTH SIDES LOST”
a. PAVN-VC:
• Huge defeat: 45,000 PAVN-VC killed – mostly VC incl. top fighters/leaders
• Lost territory in South; PAVN sent new leaders South
• Army needed 4 yrs to recover
• Apr 1969: issued DIRECTIVE 55 – ‘Never again are we going to risk our entire military force.’
• Le Duan weakened; TRUONG CHINH took over PAVN → rebuilt PAVN for 1975 victory
• 3 Apr 1968: Hanoi opened negotiations.
b. South Vietnam:
• 14.3k civilians killed, 70k homes destroyed, 627k new refugees
• Shock: war reached cities; 80% of towns/villages briefly captured
• End of democratic phase – Thieu + CAN LAO Party seized power → dictatorship
c. USA:
• 1.5k US troops killed – relatively low, but Tet = psychological defeat/’futility of war’
• ‘Credibility gap’ – Westmoreland’s ‘END IN VIEW’ tour vs. what people were seeing on their TV (eg Saigon Embassy attack)
• Execution on camera of NGUYEN VAN LEM on camera and My Lai undermined America’s moral right to be in Vietnam
• LBJ chose not to stand again; Westmoreland replaced by Abrams → move to ‘VIETNAMISATION’
• Shift in policy: no more escalation, search for peace talks
