  • 00:00

    The Vietnam War was one of the bloodiest and most violent conflicts in the second half

  • 00:04

    of the 20th century.

  • 00:07

    After the First Indochina War, Vietnam was divided into two states, North and South,

  • 00:13

    with those in the North being mostly communist and those in the South, capitalist.

  • 00:18

    It was agreed to hold a referendum a year later, with the intention that the Vietnamese

  • 00:23

    would vote on whether to remain divided or reunify.

  • 00:27

    But this never happened, as the South's leaders, in an attempt to avoid reunification from

  • 00:32

    happening, began a coup d'état.

  • 00:36

    Thus began a long war of attrition in which the U.S. and several allied countries supported

  • 00:41

    South Vietnam with arms and troops, while North Vietnam would be backed by China and

  • 00:49

    the Soviet Union.

  • 00:50

    A North Vietnamese-backed guerrilla group, called the Vietcong, having a clear disadvantage

  • 00:54

    in terms of weapons and soldiers, but a great knowledge of the terrain and battlefield,

  • 00:59

    began using ingenious and unorthodox traps that proved to be quite effective and terrifying

  • 01:05

    against the enemy.

  • 01:06

    Today we’ll learn about the dreaded "booby traps" that managed to stand up to an army

  • 01:14

    armed to the brim, welcome to Copernicus’s Galaxy.

  • 01:18

    Punji sticks or Punji stakes

  • 01:22

    This type of trap was one of the simplest and most rudimentary employed by the Vietcong,

  • 01:26

    since anyone was capable of making them, being the most infamous of all, and accounting for

  • 01:31

    2% of the wounds suffered by U.S. soldiers.

  • 01:36

    The traps consisted of boards glued to bamboo stakes cut diagonally making them very sharp.These

  • 01:42

    slats were hidden in a small hole, which was covered by a thin wooden plate that was camouflaged

  • 01:48

    with leaves, branches and grass.

  • 01:51

    The spikes were also often covered with animal waste or poison to facilitate the infection

  • 01:56

    of the wound and to delay the advance of the troops.

  • 01:59

    From these traps they began to create different variants that adjusted to each situation,

  • 02:04

    making them less and less predictable.

  • 02:07

    In addition, none of the traps needed the presence of the Vietnamese soldiers to be

  • 02:11

    triggered.

  • 02:13

    On the contrary, they used them to determine the location of the enemy, thanks to the screams

  • 02:17

    of pain that the soldiers produced when they fell into them.

  • 02:21

    Among them was the plank trap, which consisted of a mechanism placed on the ground.

  • 02:26

    When it was stepped on, it was activated, coming up and nailing all the spikes in the

  • 02:31

    stomach or chest of the unfortunate soldier.

  • 02:34

    The ingenuity of their traps had no limits, taking their now characteristic bamboo spikes

  • 02:39

    to new heights by means of mud, wood or metal that they fastened to the trees with a primitive

  • 02:45

    system of cables.

  • 02:47

    When activated, this heavy metal mace would fall at great speeds, generating a pendulum

  • 02:52

    effect, which was intended to impale several soldiers at a time in true Indiana Jones style.

  • 02:58

    And if your idea was to try to take refuge in one of the abandoned structures in the

  • 03:02

    jungle villages, we regret to inform you that it would be in vain...above the doors, death

  • 03:08

    traps made of a wooden structure with spikes at different heights were also installed,

  • 03:13

    which were triggered as soon as the doors were opened, perforating multiple parts of

  • 03:17

    the body and often ending the life of anyone who tried to enter.

  • 03:22

    U.S. soldiers had to always be alert, because the environment itself was turning against

  • 03:27

    them.

  • 03:28

    They could not trust anything, because what seemed safe could be a ticket to hell.

  • 03:33

    Many of the existing bridges were manipulated and cut slightly in half or created from the

  • 03:38

    beginning to fail, throwing many soldiers towards spikes camouflaged under water or

  • 03:44

    mud.

  • 03:45

    You may wonder how many different traps could be made with the same simple idea of a few

  • 03:50

    cut bamboo rods or sharp pieces of metal?

  • 03:52

    But the resourcefulness of the Vietcong soldiers knew no bounds, so there are still several

  • 03:58

    more to mention.

  • 04:00

    For example, the so-called "Venus flytrap", which clearly referring to the mechanism by

  • 04:06

    which these carnivorous plants obtain their food, consisted of the same main idea of the

  • 04:11

    square hole dug in the ground.

  • 04:13

    But this time with movable spikes that did not hurt you when you fell, but rather damaged

  • 04:18

    the soldier's leg when trying to pull it out of the trap, tearing it at the slightest movement.

  • 04:24

    But undoubtedly one of the most fearsome was the side-locking ones, which consisted of

  • 04:29

    two spiked wooden boards supported by a pair of thick elastic bands that were placed inside

  • 04:34

    a camouflaged hole.

  • 04:37

    When the person fell into the hole, it would close, perforating the soldier on both sides

  • 04:42

    and turning him into a human sandwich.

  • 04:45

    There was also a variant, born from the homemade bear traps that, since ancient times, the

  • 04:51

    Vietnamese inhabitants used for hunting.

  • 04:54

    It consisted of the same original trap, where they made a slight central cut so that, when

  • 04:59

    stepped on by the enemy, it would give way under the weight, splitting in two and sticking

  • 05:04

    the spikes into the sides of the leg.

  • 05:07

    If a bear trap wasn't enough, how about a tiger trap?..Those soldiers, who had miraculously

  • 05:14

    avoided all the previous traps, did not expect a large wooden board with metal spikes on

  • 05:19

    it, tied to trees and a pile of heavy stones on top, to fall from the heights.

  • 05:25

    This trap was activated thanks to an undetectable cable stretched at ankle height that activated

  • 05:30

    the deadly mechanism as soon as the soldier passed in front of it.

  • 05:35

    All of these traps were simple but ingenious so far.

  • 05:38

    However, the Vietcong soldiers did not limit themselves to the use of bamboo and metal

  • 05:44

    spikes alone, moving on to more elaborate tools.

  • 05:48

    The Vietnamese guerrillas developed an automatic mechanism to launch arrows into the chest

  • 05:53

    of their enemies by means of an elaborate system of taut strings and pieces of bamboo

  • 05:58

    that fired the pointed projectile into the victim at a 45-degree angle when the victim

  • 06:04

    triggered the trap by passing over the strategically placed wire.

  • 06:08

    The last punji trap is a classic one from the movies, consisting of a bamboo pole with

  • 06:13

    multiple spikes on one end that was attached to a log and bent backwards to form an arch

  • 06:18

    that was attached to a rope system.

  • 06:21

    When the soldier passed in front of the trap, he would activate the rope, which released

  • 06:26

    the bamboo pole, impaling the victim at a speed of approximately 160 km/hr.

  • 06:34

    Explosive Traps.

  • 06:38

    Within this category were the usual grenades, mines and mortars, which by themselves had

  • 06:43

    no merit.

  • 06:44

    But as with the previous section, what makes them interesting are the clever and inventive

  • 06:49

    ways in which they were utilized.

  • 06:51

    The greatest example of explosives used this way was the flag traps.

  • 06:57

    It was well known to everyone that the U.S. military liked to capture the enemy's flag

  • 07:02

    after controlling a position or winning a battle, as a trophy.

  • 07:07

    So the Vietcong came up with the idea of tying the flag's rope to the safety pin of a grenade

  • 07:12

    placed at the base of the flagpole, so that when the flag was taken, an explosion would

  • 07:17

    blast the soldier who lowered it.

  • 07:19

    On the other hand, the use of mines was much less creative, being used to protect the entrances

  • 07:25

    to the tunnels that the Vietcong built for their mobility and difficult detection.

  • 07:31

    They were placed on either side of the entrance so that when U.S. soldiers peeked in to inspect

  • 07:36

    them, they were detonated by a Vietcong member.

  • 07:40

    Typical grenade traps were also used, placed in the middle of the road, with a wire attached

  • 07:44

    to the safety pin and a wooden stake to keep the wire taut.

  • 07:49

    This way, when the soldier came in contact, he would press it, activating a grenade that

  • 07:54

    would explode instantly.

  • 07:56

    Only this time they would hide them inside food cans or place them underwater where they

  • 08:00

    were practically undetectable.

  • 08:03

    Mortars were another type of rudimentary trap that were placed underground, inside a piece

  • 08:08

    of bamboo, leaving a small space where they’d put any object capable of setting off the

  • 08:13

    firing pin at the slightest amount of pressure, detonating the mortar.

  • 08:18

    Another similar trap was also used with bullets, which when triggered, would perforate the

  • 08:23

    foot of the poor devil who had fallen into the trap.

  • 08:28

    Rudimentary Biological Traps

  • 08:31

    The U.S. military had highly dangerous and terrifying laboratory-produced chemicals at

  • 08:36

    its disposal, but the Vietnamese guerrilla group had managed to make their own biological

  • 08:42

    traps, which, although much more primitive, managed to provoke panic among the unfortunate

  • 08:47

    soldiers who set one off.

  • 08:50

    The Vietcong used any resource at their disposal as a weapon against their enemy and animals

  • 08:55

    were no exception.

  • 08:57

    Mainly, these traps used two types of poisonous animals.

  • 09:01

    First, there were the wasp traps, which consisted of a box with thousands of these small insects

  • 09:07

    inside that were released by means of the now typical tensioned

  • 09:11

    wire system.

  • 09:13

    This trap was especially effective when combined with the Punji traps, as the soldiers were

  • 09:18

    panicked by the stings of the swarming wasps and ran away without paying attention to their

  • 09:23

    surroundings, ending up impaled on one of these traps.

  • 09:27

    One of the most dreaded traps mentioned in this video are the highly venomous snake

  • 09:31

    pits.

  • 09:34

    These traps had multiple variations.

  • 09:36

    They were not only limited to making holes, they also hid these poisonous animals in gun

  • 09:41

    cases, backpacks, tunnels or even nailed to trees, so that when the soldiers picked up

  • 09:46

    the purposely left supplies or simply walked past these trees, they would be bitten by

  • 09:51

    a furious and hungry poisonous snake, which was nicknamed by the U.S. soldiers themselves

  • 09:57

    as "Two-Step Charlie" because you could only take two steps after being bitten before the

  • 10:02

    venom killed you or paralyzed the affected limb.

  • 10:07

    Trap markers

  • 10:11

    Clearly not all Vietcong soldiers had the ability to remember the position of each of

  • 10:15

    their traps perfectly.

  • 10:17

    Because they were so difficult to detect, it was a double-edged sword, as any soldier,

  • 10:22

    friend or foe, could fall victim to the "booby traps".

  • 10:27

    This led the Vietnamese guerrillas to leave signs or marks to help them avoid falling

  • 10:31

    into their own traps.

  • 10:33

    These ranged from branches arranged in a special way or strange shapes with bamboo structures,

  • 10:39

    among others.

  • 10:40

    Such signals would also be an opportunity for the enemy to detect them in time.

  • 10:45

    But it was still very difficult for the weary soldiers to pay attention to even the smallest

  • 10:50

    detail, which caused them to fall victim to these dreaded traps.

  • 10:55

    Human ingenuity is fascinating, especially when it tests our ability to survive in a

  • 11:00

    conflict, even if this often leads to unnecessary suffering...

  • 11:05

    whether in favor of progress or under the yoke of war, we'll be here to tell you about

  • 11:10

    it, at Copernicus’s Galaxy.
