The NLF was a guerrilla movement trained in conducting ambushes and it had support in the North and South of Vietnam. The Viet Cong lay traps, and used cover of the jungle in their surprise attacks. They were supplied through the Ho Chi Minh Trail, created in 1959 to carry supplies from the North to the South. The trail was made up of 100s of interlocking trails that all led from the North to the South, some passing through Laos and Cambodia, walking along it could take up to two months.
