## January

[edit]

Writing in Harper's Magazine retired U.S. general James M. Gavin proposed an enclave strategy where U.S. forces would defend coastal enclaves where most of the population and economic activity was concentrated and act as a strategic reserve, leaving the ARVN to fight the PAVN/VC further inland. This strategy was designed not to achieve victory, but rather to create a stalemate forcing the PAVN/VC to seek a negotiated solution. In later years the "Gavin Plan" would become known as "light at the top, heavy at the bottom" reflecting the population concentration of South Vietnam.[9]
