Ho Chi Minh trail
During The Vietnam War Ho Chi Minh trail was a logistical system that ran from the Democratic Republic of Vietnam (North Vietnam) to the Republic of Vietnam (South Vietnam) through the neighboring Laos and Cambodia and was used by the North Vietnamese as a route for its troops to get into the South. Also Ho Chi Minh trail was used as a supply route – for weapons, food and equipment. It was not just one trail but a series of trails.
In total the trail was about 1,000 kilometres in length and consisted of many parts and ran along the Laos/Cambodia and Vietnam borders and was mostly covered with jungles. This natural environment was an excellent cover for this rout.
Initially, all cargos were delivered on foot or even by elephants. Al these methods were quickly replaced with trucks (most of all Soviet or Chinese).
During 1965 the amount of transported supplies almost equaled the total sum for the previous five years.
The interdiction of the system quickly become one of the top American priorities, but it was complicated due to Laos’s neutrality. However, this didn’t prevent the North Vietnamese from violating Laos’s neutrality by expanding their supply route.
On 14 December 1964, the U.S. Air Force’s carried out the first systematic bombardment of the Hồ Chí Minh trail in Laos. From then, many bombing operations such as«Barrel Roll», «Steel Tiger», «Tiger Hound», «Commando Hunt» took place on territory of Laos. The intensity of bombardments reached its peak in period 1969-1971, but U.S. Air Force could never cut the supply by Ho Chi Minh trail. In 1973 all bombings were ceased by United States Congress requirement.
