This incident happened in early 1972 during the Vietnam War. A US Special Forces group was secretly delivered at night and parachuted in an area on the Cambodia-North Vietnamese border.
The operation was vital: to destroy a facility in North Vietnam, which, as it was possible to establish by American intelligence, was secretly overhearing top secret conversations of the US Army in South Vietnam.
The SWAT team set up camp for the night, preparing to assault the North Vietnamese team at dawn. In the early morning, the commandos quietly crept up to the Vietnamese base, but what they saw there shocked and frightened them.
As the team got closer to the location of the North Vietnamese unit, they suddenly discovered that there was a large spherical ship that stood on three sturdy metal supports.
The ship suddenly began to hum, causing instant sickness, dizziness, and disorientation in the US military.
The group leader was about to issue a command to retreat when a group of strange looking humanoid creatures appeared.
Not believing what they saw, the special forces group was even more frightened by what these creatures were doing (according to the description of the soldiers, taking into account modern data based on numerous contacts, it can be assumed that they were “gray”): the aliens got out of a large pile various parts of human bodies and placed them in large containers – arms, legs, torso, heads; this terrible list went on and on.
Some were the remains of white people, others were black (US Army soldiers), and others looked like Vietnamese (Vietnamese soldiers from the base).
What they saw sobered and angered the special forces and the commander gave the order to open fire – the bullets hit the bodies of the creatures, but they did not do any harm, except for one who was killed by a shot in the head.
Several commandos were killed, and others were seriously injured by the effects of unknown weapons. Then the aliens quickly retreated into the ship and he quickly rushed into the sky,
Soon, another CIA team appeared on the scene, as one of the survivors said they were all given some kind of mind-altering drugs to try to make them forget about this incredible fight. And it worked, at least for a while.
However, in the late 1980s, two members of the special forces team who took part in that battle began to have nightmarish memories of the events of April 1972, which prompted one of them to contact many other special forces who were found and who were still alive.
Two had already died, three were not found at all, but the rest were able to meet in August 1988 and decided that this story should be told.
They turned to researcher and ufologist Leonard Stringfield and he published their story in his 1991 book.
The story is told in Stringfield’s UFO Crash Retrievals: The Inner Sanctum.
