an American adviser recommended it unless the recommendation came in
the most inconspicuous and subtle of fashions. At one point, the Americans
tried to spur the South Vietnamese on by assigning them quotas of Viet Cong
cadres to be captured or killed, but the South Vietnamese either fabricated
statistics to meet the quotas or ignored them.59
From 1969 to 1971 the invigorated South Vietnamese forces and their
American allies eliminated the remaining South Vietnamese insurgents by kill-
ing them, capturing them, or driving them to defect through the national am-
nesty program. e war ceased to have a signicant component of insurgency
by the end of 1971, becoming a purely conventional war between the armed
forces of North Vietnam and South Vietnam.60 At the end of March 1972, by
which time President Richard Nixon had completed a phased withdrawal of
all U.S. ground forces, a whopping fourteen North Vietnamese army divisions
slashed into South Vietnam in a three-pronged oensive known to Americans
as the Easter Oensive, to North Vietnamese as the Strategic Oensive, and to
South Vietnamese as the Summer of Fire. Making liberal use of armor and ar-
tillery, the North Vietnamese overran Quang Tri, the northernmost province
of South Vietnam, and advanced on two pivotal provincial capitals, Kontum
and An Loc. Seeing the deciencies of some of the South Vietnamese mili-
tary commanders, President ieu replaced a few key ones with outstanding
ocers from other commands, and they quickly restored the ghting spirit in
the South Vietnamese army units. In the next few months, with the support of
U.S. air and naval power, the South Vietnamese blunted the remaining North
Vietnamese assaults and drove the invaders from the populous areas they had
seized. On account of the Saigon government’s control of South Vietnam’s vil-
lages, it alone could rely heavily on villagers for recruits, food, and intelligence,
which proved to be critical assets during the oensive.
In the end, however, the obliteration of the insurgents did not save South
Vietnam from defeat. President Nixon withdrew America’s remaining advi-
sory and support personnel from South Vietnam in January 1973 in return for
North Vietnamese promises to end the ghting and repatriate American pris-
oners of war, while promising President ieu that the United States would
come to South Vietnam’s assistance if the North Vietnamese launched another
major oensive. But when 550,000 North Vietnamese army troops attacked
two years later, Nixon was out of oce because of Watergate, and the U.S.
Congress prevented his successor, Gerald Ford, from fullling Nixon’s prom-
ise. e Congress also refused to provide South Vietnam with the fuel, equip-
