The Haunting Truth Behind Vietnam’s Operation Wandering Soul

During the Vietnam War, the United States military employed a range of tactics to demoralize the enemy and gain a strategic advantage. One particularly unconventional approach was Operation Wandering Soul, a psychological warfare campaign aimed at instilling fear and uncertainty in the Viet Cong soldiers. By capitalizing on Vietnamese folklore and beliefs surrounding the afterlife, the U.S. Army created a haunting audio broadcast known as “Ghost Tape Number 10.” In this article, we will delve into the eerie origins of this operation, examine its impact, and explore the lasting legacy of this haunting chapter in history.

The Legend of the Wandering Soul

Vietnamese culture is deeply rooted in folklore and spirituality, with beliefs about the afterlife playing a significant role in their traditions. According to local legends, the spirits of the dead who were not properly buried would wander the earth in torment until their remains were found and given a proper burial. It was also believed that on the anniversary of a person’s death, a spiritual channel between the living and the afterlife would open, allowing communication with the departed souls. This belief formed the foundation for the psychological manipulation employed by Operation Wandering Soul.

The Birth of Operation Wandering Soul

Operation Wandering Soul was born out of the U.S. military’s desire to exploit the deeply ingrained cultural beliefs of the Vietnamese people. Drawing inspiration from the “Ghost Army” recordings used during World War II, the U.S. Army’s 6th Psychological Operations Battalion (6th PSYOP) collaborated with the U.S. Navy to create a series of audio broadcasts designed to strike fear into the hearts of the enemy.

Ghost Tape Number 10: A Haunting Broadcast

At the heart of Operation Wandering Soul was a chilling audio recording known as “Ghost Tape Number 10.” This tape featured a combination of eerie sounds, including wailing voices, sobbing women, and a child’s voice calling for her father. The centerpiece of the broadcast was the voice of a purported deceased Viet Cong soldier, pleading with his comrades and warning them of the horrors that awaited them in the afterlife. The broadcast was strategically played in the jungle, giving the impression that the sounds were emanating from all directions, heightening the psychological impact on the enemy soldiers.

Psychological Warfare on the Battlefield

The impact of Operation Wandering Soul was twofold. Firstly, it sought to exploit the fear and superstitions deeply ingrained in Vietnamese culture. By invoking the specter of tormented souls doomed to wander the earth, the U.S. military aimed to sow doubt and uncertainty among the Viet Cong soldiers, making them question their cause and their own mortality. Secondly, the operation aimed to create a psychological wedge between the Viet Cong soldiers and their commanders. The haunting messages played upon the soldiers’ fears of eternal damnation and served as a constant reminder of the cost of their actions.

The Effectiveness of Operation Wandering Soul

The effectiveness of Operation Wandering Soul varied, with mixed results reported by different American units. In some instances, the broadcasts led to enemy soldiers abandoning their positions, while in others, the Viet Cong saw through the ruse and concentrated their fire on the helicopters carrying the speakers. However, even when the enemy soldiers were not fully convinced of the supernatural nature of the broadcasts, the psychological impact remained significant. The messages played upon their anxieties about dying far from home and likely sapped their morale.

Expanding the Psychological Arsenal

As Operation Wandering Soul continued, the U.S. military sought to expand its psychological warfare tactics. One notable addition was the inclusion of tiger growls in the broadcasts. Building on local legends and fears surrounding these powerful predators, the aim was to further unsettle the enemy soldiers and force them to question their safety and control over their surroundings. The addition of these sounds reportedly led to mass desertions and further solidified the psychological impact of the operation.

The Legacy of Operation Wandering Soul

Operation Wandering Soul stands as a testament to the ingenuity and creativity of psychological warfare tactics employed during the Vietnam War. While the operation may have been unsettling and manipulative, it demonstrated the power of exploiting cultural beliefs and superstitions to gain an advantage on the battlefield. The haunting broadcasts serve as a reminder of the lengths to which nations will go in their pursuit of victory, even if it means tapping into the supernatural realm.


Operation Wandering Soul remains a haunting chapter in the Vietnam War, showcasing the lengths to which the U.S. military went to demoralize the enemy and gain a psychological advantage. By capitalizing on Vietnamese folklore and beliefs surrounding the afterlife, the U.S. Army created a chilling audio broadcast that struck fear into the hearts of the Viet Cong soldiers. While the effectiveness of the operation varied, its psychological impact cannot be denied. Operation Wandering Soul serves as a stark reminder of the power of psychological warfare and the lengths nations will go to achieve victory on the battlefield.
