10 Provinces were included in III Corps stretching from where the central highlands blended into the flat
alluvial plain of the northern Mekong Delta to the Delta itself, and from the Cambodian border in the west past Saigon to
the South China Sea. The major cities were Tay Ninh, Bien Hoa and Vung Tau. While it surrounded the Saigon Capital Special
Zone, Saigon was not a part of III Corps.
