    During World War II, a massive recruitment effort targeted students from the top art schools across the country. These young designers, artists, and makers were being asked to help execute a wild idea that came out of one the nation’s most conservative organizations: the United States Army.

    The crazy idea was this: The United States Army would design a “deception unit”: a unit that would appear to the enemy as a large armored division with tanks, trucks, artillery, and thousands of soldiers. But this unit would actually be equipped only with fake tanks, fake trucks, fake artillery and manned by just a handful of soldiers.

    June 6, 1944, marked the start of the most critical period of World War II. The Allies landed on the beaches of Normandy and began to liberate France from Germany, who had occupied it for four years. The success of D-day was due, in part, to deception. Using a variety of techniques, the allies were able to trick the Germans into thinking the invasion would happen at a different time and place.

    Then, a couple of U.S. army men stepped in with an idea. Ralph Ingersoll and Billy Harris, who had learned some deception techniques from the British, wanted to take deception to a whole new level. They wanted to create a mobile deception unit.

    The army created a top-secret unit officially called, “The 23rd Headquarters Special Troops.” After the war, it was nicknamed “The Ghost Army.”

    The so-called Ghost Army would impersonate a specific larger division, such as the 6th Armored Division, which had fifteen to twenty thousand soldiers. Only about a thousand soldiers comprised the Ghost Army.

    To pull of this deception, the Ghost Army used tanks, jeeps and artillery all made from inflatable rubber.

    For the charade to be believable, soldiers in the Ghost Army had to pay extreme attention to detail. An inflatable tank might look real enough on the ground from a distance, but aerial reconnaissance could reveal a conspicuous lack of tank tracks. So the Ghost Army would use a bulldozer to make fake tracks around the fake tanks.

    There was one cardinal rule about working with inflatables: never carry one across a road, or in any other place where you could be seen. Obviously, two men carrying a 40-ton tank would be a dead giveaway.

    When they weren’t busy with their dummy tanks, the artists in the Ghost Army spent their time sketching each other as well as local people and architecture.

    Some of the artists in the Ghost Army went on to be quite successful: Ellsworth Kelly, minimalist sculptor and painter; Bill Blass, the fashion designer; and Jack Masey, a designer who has worked on numerous world expositions and museums.

    During their travels through Europe, when they weren’t sketching, the Ghost Army was often acting—literally impersonating whichever unit they imitating at the time. They made fake patches to put on their sleeves and stenciled fake unit numbers on their trucks.

    While passing through local towns the ghost army would put on a show for any German spies that might still be lingering in French cafés or bars.

    On the battlefield, the Ghost Army also did “sonic deception.” The sonic deception unit would record the sounds of troops amassing in tanks and trucks and then be able to play those sounds back over loud speakers.

    The Ghost Army had a library of recordings of different engines moving over different terrain. Sonic Deception was so new to the Army that they made a top secret film (screened for a chosen few) to explain how it worked.

    The third component of the Ghost Army were the radio operators. It was well known that the Germans listened in on radio communications of allied troops, so if the Ghost Army was trying to impersonate a real armored division, they’d have send the right kinds of transmissions.

    The radio operators had to be perfect mimics. They had to learn the exact keystrokes of an individual Morse Code operator in the unit they were impersonating.

    The three different units in the Ghost Army—visual, sonic, and radio—were operating separately but were organized by the same people and were working on different components of the same plan.

    The Ghost Army carried out twenty-one deception missions between June 1944 and March 1945—nearly the entire time the U.S. Army was operating in Europe. One of these was Operation Bettembourg, in which The Ghost Army filled a 75 mile gap in the American line of troops for 7 days, until an actual armored division could come in and take their place.

    Over the course of the war, the Ghost Army lost three soldiers, and had several dozen wounded, but overall it was one of the safer assignments of WWII. And in the end, the crazy idea of a “mobile deception unit” worked. They fooled the Axis powers, they held the line, and they saved lives.

    99% Invisible producer Katie Mingle spoke with Rick Beyer, co-author (with Elizabeth Sayles) of The Ghost Army of World War II, which includes many more images, plus details of specific operations performed by the Ghost Army. Katie also spoke with Jack Masey who went on to design a number of world expositions and museums after the war.

  3. To The Best of Our Knowledge: Alan Turing

    The driving force behind modern computers, Alan Turing was born a hundred years ago. He launched the digital age, founded the fields of computer science and artificial intelligence, and helped the British win WWII by cracking the Nazi "Enigma" codes. He was persecuted by British authorities for the crime of being homosexual, and committed suicide at age 41. His life ended tragically, but his brilliance lives in the computers we use every day. We celebrate the Alan Turing Year.

  4. The WASPs: Women Pilots of WWII

    In the early 1940s, the US Airforce faced a dilemma. Thousands of new airplanes were coming off assembly lines and needed to be delivered to military bases nationwide, yet most of America’s pilots were overseas fighting the war. To deal with the backlog, the government launched an experimental program to train women pilots to fly military aircraft.
