eastern offensive

Question 1

📍 Background

Answer 1

By 1972, US troops were withdrawing under Nixon’s Vietnamisation policy.

ARVN (South Vietnamese Army) now expected to carry main fighting role.

North Vietnam wanted to test ARVN strength without full US combat support.

Offensive timed during US election year → put pressure on Nixon.

Question 2

Events of the Offensive

Answer 2

30 March 1972: NVA launched a massive conventional attack across the 17th parallel.

Largest assault since Tet Offensive (1968).

Around 120,000 North Vietnamese troops supported by tanks, heavy artillery, and Soviet-supplied weapons.

Attacked in three main areas:

Quang Tri Province (north).

Central Highlands.

Mekong Delta.

ARVN initially struggled → several units collapsed.

Quang Tri City fell in May 1972 → major blow to South morale.

Question 3

US Response

Answer 3

Nixon launched Operation Linebacker (May–October 1972).

Heavy bombing of North Vietnam → targeted roads, railways, supply routes.

US used B-52 bombers, precision bombs, and naval mines in Haiphong Harbour.

Bombing + air superiority helped ARVN regroup.

By September 1972, ARVN retook Quang Tri City.

Question 4

Consequences

Answer 4

ARVN performance mixed:

Showed they could fight with US air/naval support.

But high desertion rates and poor morale showed weaknesses.

North Vietnam’s losses: estimated 100,000 killed/wounded; but proved they could launch large-scale conventional warfare.

US domestic politics: Nixon portrayed ARVN “victory” as success of Vietnamisation → boosted his re-election campaign (won Nov 1972).

Offensive pressured US + North Vietnam into serious negotiations → paved way for Paris Peace Accords (Jan 1973).

Demonstrated South Vietnam’s reliance on US air power → without it, ARVN could not stand alone.

Question 5

Evaluation Points

Answer 5

Unlike Tet, Easter Offensive was conventional warfare, not guerrilla.

Militarily: North suffered heavy losses → but psychologically proved South still weak.

Politically: Nixon gained leverage for “peace with honour” → Paris Peace Accords possible.

Long-term: showed ARVN could not survive without direct US backing → when US left in 1973, South Vietnam was vulnerable → led to Fall of Saigon (1975).

Question 6

Key Stats to Remember

Answer 6

Launched 30 March 1972.

120,000 NVA troops with Soviet tanks/artillery.

Quang Tri City captured in May, retaken Sept 1972.

100,000 NVA casualties (approx).

US launched Operation Linebacker, mined Haiphong Harbour.

Direct lead-up to Paris Peace Accords (Jan 1973).
