Gen. J. Lawton Collins was made ambassador to "Free Vietnam"
Then South Vietnam
In late 1954, Gen. J. Lawton Collins was made ambassador to "Free Vietnam" (the term South Vietnam came into use in 1955), effectively elevating the country to sovereign status. Collins' instructions were to support the leader Ngo Dinh Diem in subverting communism, by helping him to build an army and wage a military campaign.
