1974 in the Vietnam War

1974 saw ongoing combat in South Vietnam despite the promises of the Paris Peace Accords. The impact of the 1973 oil crisis, reduced U.S. expenditure and the resignation of Richard Nixon in the wake of the Watergate scandal undermined the South Vietnamese economy and U.S. support for South Vietnam. The South Vietnamese were forced to reduce military operations to conserve fuel and ammunition, causing a decline in morale and moving the balance of military power in favor of the North Vietnamese.

General Murray sent a cable to The Pentagon criticising reductions in military aid saying that "you can roughly equate cuts in support to loss of real estate" and that as aid decreased South Vietnam would be forced to retreat to a rump state based on Saigon and the Mekong Delta. Murray advised that South Vietnam needed a minimum aid level of US$1.126 billion, but even this would not replace lost and damaged equipment, with aid of US$900 million military capacity would decline after mid-1975, with aid at US$750 million South Vietnam would be unable to stop a major attack, while at US$600 million the US should "write off South Vietnam as a bad investment and broken promise."

Finally on 6 January 1975, without food and water and with nearly all ammunition expended, the company picked up its wounded and withdrew down the mountain to friendly lines.
