The Ghost Army That Duped The Nazi Germany

Deception and decoy are part of war strategy. During the Second World War the Allied forces employed dozens of tricks to confuse, mislead or intimidate the German army — from dropping dummy paratroppers to dropping aluminum tinfoil, from faking the death of a fictitious Major William Martin to completely covering up a military aircraft plant. One such deceptive operation that came to light only a few years ago is the so called Ghost Army.

The Ghost Army was a 1,100-man unit officially known as the 23rd Headquarters Special Troops whose goals were to impersonate vastly large U.S. Army units to deceive the enemy. The men that made up this secretive unit weren’t your regular soldiers. They were artists, illustrators and sound technicians handpicked for the job from New York and Philadelphia art schools. They didn’t carry M1s and Thompsons, but large inflatable tanks and rubber aircrafts, powerful amplifiers and speakers to mimic the noise created by a large gathering troop and radio equipment to transmit phony messages.



Over the course of the war, the Ghost Army travelled all across Europe staging a sort of “traveling road show of deception” aimed at Hitler’s legions. They staged more than 20 operations where they conjured up phony convoys, phantom divisions and make-believe headquarters to fool the enemy about the strength and location of American units. The Ghost Army is estimated to have saved tens of thousands of soldiers' lives with its deceptions, yet almost no one knew about them. Their existence and their every move were highly classified and remained so for more than 40 years after war ended.

To create the impression of a huge army, the unit would set up inflatable tanks, trucks, artillery and airplanes, and play pre-recorded sounds of armored and infantry units through giant speakers that could be heard up to 15 miles away. Radio operators created phony traffic nets, actors dressed as soldiers hung out at local cafes and spun counterfeit stories for spies to pick up, while another impersonated a major general and drove from town to town in a convoy of jeeps. Sometimes the unit would drive just a couple of trucks in loops to create the illusion of an entire infantry unit being transported. Often the thousand-men-unit would impersonate the presence of twenty to forty thousand men.


Dummy M-4's like this one were the mainstay of Ghost Army visual deceptions. The unit had literally hundreds of these.

One of their biggest performance came towards the end of the war. In March 1945, as the 9th Army prepared to cross the Rhine into Germany, the 23rd was called upon to feign a crossing in a different place to draw German units away from the point of the real attack. More than 600 inflatable tanks and artillery were set up. At night they played the sounds of trucks rolling in. In the daytime they played sounds of heavy construction, as if bridging units were being put together. Artillery fire was mimicked by setting off flash canisters. While the Germans concentrated their effort over a rubber army, the real one successfully made the crossing facing minimum resistance.

After the war, many of the men who served in the unit, went on with their art careers. Some became famous, including fashion designer Bill Blass, painter Ellsworth Kelly and photographer Art Kane. Fewer than 50 of the men are left today. They found recognition after more than seventy years, thanks to a PBS documentary titled The Ghost Army released in 2013, where several of the members were interviewed.

Xe Bang Fai River Cave

Tham Khoun Xe Cave, also known as Xe Bang Fai River Cave, is an immense river cave located in a remote corner of Khammouane Province in central Laos. It is believed to be one of the largest river cave in the world with enormous passages some 120 meters tall and 200 meters wide.

The Xe Bang Fai River originates in the Annam Trung Sun Mountains on the border between Lao and Vietnam and flows across the Nakhai Plateau en route to the Mekong River. The Nakhai Plateau is composed of sandstones and massive carbonates layers which the river had dissolved to create Tham Khoun Xe, a subterranean channel 7 km long.



The cave is well-known to the Lao people who for centuries have fished in the river downstream from the cave exit, and scaled its entrance walls to harvest bird’s nests. The first European exploration were carried out in 1904, and then again in 1905 by French explorer Paul Macey and his team in bamboo rafts. No further attempts at exploration were made for the next ninety years after which, due to reasons unknown, the area was closed off to foreigners. The cave was finally opened with great reluctance in 2005-2006 for western kayakers. Since then, French and North American teams are operating in the area.

The entrance to the cave is a 60-meters tall arch at the base of an imposing limestone amphitheater over 150 meters tall. The river passage on average is 76 meters wide and 53 meters tall, but frequently exceeds 100 meters in width in places. The largest passage widths, the teams discovered, were 200 meters. The cave passage is between 4 to 12 meters deep. Many stalagmites here are more than 20 meters high, and some of the cave pearls seen were 32 cm in diameter.

The Painted Dunes in Lassen Volcanic National Park

The Painted Dunes are multicolored pumice fields formed by oxidation of volcanic ash as they fell out of volcanic eruptions that have sculpted the area inside Lassen National Park in Northern California. The ash on Painted Dunes is brightly oxidized because it fell on lava flows when they were still hot. The Painted Dunes, along with Fantastic Lava Beds, and other eccentric geological features lie near Cinder Cone, a 700-foot tall cinder cone volcano that’s believed to have last erupted in 1650s.

Cinder Cone is composed of loose scoria – a material which began as blobs of gas-charged lava thrown into the sky during an eruption, but fell as hardened volcanic rock containing cavities created by trapped gas bubbles. Later, like many cinder cones, it was snuffed out when several basalt lava flows erupted from its base, creating what has been named the Fantastic Lava Beds.



There are actually two scoria cones at Cinder Cone—the remnants of a nearly completely buried earlier cone can be seen on the larger cone's south side. Much of the earlier cone was probably destroyed by lava flows erupting from its base. The blocks of red, cemented scoria within the Painted Dunes lava flows are pieces of this earlier cone, which were carried away by the flowing lava.

There is a great hiking trail to the top of Cinder Cone from where you can marvel at the landscape transformed by volcanic activity. Climbing the cone is a challenge because of all the loose rocks that keep sliding you down. Painted Dunes is located down the South East face of the cone, and just beyond the Fantastic Lava Beds.

Largest Non Nuclear Explosion

At the end of the Second World War, the British Army had a huge surplus of ammunition and explosives that started to give them ideas. It was suggested that the excess ammunition could be utilized for seismic experiments by setting up controlled explosions to generate seismic waves having intensity comparable with those produced by small earthquakes. It was impractical to carry out the experiments within England as explosion of the necessary size on the available sites would cause damage to nearby properties. So they turned to Germany.

The British had just concluded the biggest war in human history with Germany, and like the explosives, aggression was still in surplus quantities. In July 1946, an ammunition dump near the town of Soltau, in north Germany, was blown up producing seismic waves that were observed at distances up to 50 km. But the British needed something bigger. So they started preparing for the world’s most powerful non-nuclear explosion, which eventually came to be known as the “British Bang”. The target: a small archipelago off the German coastline called Heligoland.



Heligoland is a small archipelago located about 46 kilometers off the German coastline in the North Sea. It consist of two islands – the populated one square km main island, Hauptinsel, and an uninhabited smaller island alongside named ‘Dune’ where the island’s airstrip is located.

Because of its strategic location, Heligoland has a long military history. Originally occupied by Frisian herdsmen and fishermen, the island came under the control of the dukes of Schleswig-Holstein in 1402 and became a Danish possession in 1714. In 1807, during the Napoleonic wars, Heligoland was seized by the British fleet and formally ceded to Great Britain in 1814. In 1890, the island was transferred to Germany in exchange for Zanzibar and other African territories.

The Germans evacuated the civilian population living on the island and developed the island into a major naval base, with extensive harbor and dockyard installations, underground fortifications, and coastal batteries. The first naval engagement of the war, the Battle of Heligoland Bight, was fought near this island. When the First World War ended, the islanders returned and the island became a popular tourist resort for the German upper class. During the Nazi era, the island was again made a naval stronghold and sustained severe Allied bombing toward the end of World War II.

With the defeat of Germany, the population was evacuated, and the British decided to destroy the remaining fortifications, underground bunkers and submarine base by deep blasting, and at the same time record the explosion with seismic sensors for science.

On 18 April 1947, the Royal Navy detonated 6,700 tons of explosives creating a black mushroom cloud that curled 6,000 feet into the sky. People on the mainland 60 km away were warned to open their windows to avoid implosion, and the blast was registered as far away as Sicily. The Guinness Book of World Records lists the Heligoland explosion as the world’s largest single non-nuclear explosion in history.


The explosion at Heligoland

The detonation which released energy equivalent to a third of that released by the Hiroshima atomic bomb, shook the main island several miles down to its base. The British originally expected the island to be totally destroyed. The island survived but it’s physical shape was altered for ever. Its southern tip caved in to a huge crater, that is today a celebrated tourist spot.

The Royal Air Force continued to use the island as a bombing range until it was returned to West Germany on March 1, 1952. The town, the harbor, and the bathing resort on Düne were rebuilt, and Heligoland once again became a holiday resort.

Potash Evaporation Ponds, Utah

These electric blue shapes in the brown desert are potash evaporation ponds managed by Intrepid Potash, Inc., the United States’ largest producer of potassium chloride, and are located along the Colorado River, about 30 km west of Moab, Utah. These ponds measure 1.5 square kilometers, and are lined with rubber to keep the salts in. Unlike other salt evaporation ponds that get a naturally reddish tinge due to the presence of certain algae, the bright blue color of these potash evaporation ponds come from an artificially added dye that aids the absorption of sunlight and evaporation. Once the potassium and salts are left behind, they are gathered and sent off for processing.



Most of the world reserves of potassium came from ancient oceans that once covered where is now land. After the water evaporated, the potassium salts crystallized into large beds of potash deposits. Over time, upheaval in the earth's crust buried these deposits under thousands of feet of earth and they become potash ore. The Paradox Basin, where the mines at Moab are located, is estimated to contain 2 billion tons of potash. These formed about 300 million years ago and today lies about 1,200 meters below the surface.

To extract potash from the ground, workers drill wells into the mine and pump hot water down to dissolve the potassium. The resulting brine is pumped out of the wells to the surface and fed to the evaporation ponds. The sun evaporates the water, leaving behind crystals of potassium and other salt. This evaporation process typically takes about 300 days.

Intrepid Potash, Inc. produces between 700 and 1,000 tons of potash per day from this mine. The mine has been open since 1965, and Intrepid Potash expects to get at least 125 more years of production out of it before the potash ore runs out.
