by the Communist government of
North Vietnam.
Around this same time, the
performance of the South Vietnamese
army came under increasingly harsh
criticism. Many U.S. military advisors
stationed in the country complained
that Diem and the military leadership
of the South Vietnamese army—for-
mally known as the Army of the
Republic of Vietnam or ARVN—were
reluctant to move aggressively against
the Viet Cong. The advisors also noted
that South Vietnamese officers were
afraid that Diem would punish them if
their troops suffered many casualties.
Some U.S. observers even came to
believe that the ARVN contained sig-

agents. “The whole country had been
penetrated [by the Viet Cong], from
the palace down to the platoons,”
claims historian Bruce Palmer in The
25-Year War: America’s Military Role in

put out their orders the way we would.
They did not trust their own chain of
command. They wouldn’t tell the
troop commanders where they were
going until the last minute. And I
think that when we [the United States]
went in there, we didn’t really realize
the extent of the subversion.’”
By early 1963, the United
States had stationed more than 12,000
American advisors and pilots in South Vietnam to help the
country defend itself from the Communists. Despite this assis-
tance, however, the ARVN continued to struggle in its cam-
paign against the Viet Cong. “One had a sense on all sides of
the . . . incompetence and unpopularity of the [Diem] govern-
ment at the time,” recalled presidential advisor John Kenneth
Galbraith. “Here were just a few thousand Vietcong guerrillas
