Vietnam War History: Trying to Find Viet-Cong Tunnels with Witching Rods?

The Military Has Been Known to Try Almost Anything Once, Regardless of it’s Effectiveness

For more than five centuries, farmers, treasure hunters and others have applied a pseudoscientific practice known as “dowsing” to find water, caves, graves and more.

During the Vietnam War, American troops tried using the method to divine the location of Viet Cong tunnel networks.

It didn’t work.

Continually frustrated by the underground networks, the Pentagon made locating and destroying the subterranean passages a main goal in 1967. A year later, defense contractor HRB Singer told the Office of Naval Research that dowsing might hold the answer.

“Undoubtedly, any system that offers some promise of improving the odds above pure chance of discovering and locating the enemy is worth a try — if nothing else is available,” the scientists explained in a 1968 report. The U.S. Army and Navy had both so far failed to build a machine that could reliably detect the tunnels.

In spite of repeated studies failing to prove any scientific basis for dowsing, the practice has endured to the present day. HRB Singer was optimistic that dowsing could help in South Vietnam.

Debates have raged about whether dowsing works since the practice first evolved in Germany in the 15th century. In 1518, Christian theologian Martin Luther decried the practice as occultic — and an affront to God.
