Soldatensender Calais was a British black propaganda broadcaster during the Second World War operated by the Political Warfare Executive. It pretended to be a station of the German military broadcasting network ("Soldier's Radio Calais"). The station was in operation from 1943 to April 1945, when it ceased operations. Black propaganda is propaganda that purports to be from a source on one side of a conflict, but is actually from the opposing side. ...

During World War II, the Political Warfare Executive (PWE) was a British clandestine body created to produce and disseminate black propaganda, with the aim of damaging enemy morale. ...
Soldatensender Calais operated on the mediumwave band, with an associated shortwave station Kurzwellesender Atlantik. The station used a 600-kiloWatt transmitter originally built for American broadcaster WJZ, the NBC Red Network flagship with studios in New York and transmitting site in New Jersey. This transmitter had sat unused at the factory after the FCC imposed a 50 kW power limit, and so RCA was glad to sell it overseas. Codenamed "Aspidistra," it was installed in a huge, underground bunker, where it was briefly the world's largest mediumwave station, perfect for deceptive "black" operation.
Soldatensender Calais operated from 6 PM local time to dawn.
Star announcer of the Soldatensender was probably Sepp Obermeyer, an outspoken Bavarian who had served with the Luftwaffe but had become disaffected with the Nazis and defected by flying a Messerchmitt night-fighter through British radar and anti-aircraft defences to land it on an Essex airfield.

Calais overlooks the Strait of Dover, the narrowest point in the English Channel, which is only 34 km (21 miles) wide here, and is the closest French town to England.
The monument was proposed by the mayor of Calais for the town's square in 1880.
