I used to think that “black propaganda” was something like “propaganda pushing a black legend” or “libelous propaganda”. But like so often, there is a difference between (often vaguely defined) usage of a phrase in ordinary conversation, and its precise definition as a “term of art”.
This paper on propaganda during WW II was highly informative. Briefly, in the “business”, “white propaganda” is defined as propaganda “under true flag”: it reveals its origin and does not purport to come from a neutral or opposing side. Examples on the Axis side are the Tokyo Rose and Axis Sally radio broadcasts, as well as the “Germany Calling” broadcasts of the pseudonymous Lord Haw-Haw.
In contrast, “Black Propaganda” is defined as propaganda under false flag: originating from the opponent’s side but disguising itself as friendly, for the purpose of sowing misinformation, confusion, demoralization, or all of the above. The term “Grey Propaganda” is used for cases where allegiance of the propagandist is deliberately made vague or ambiguous.
The uncontested masters of the art of black propaganda/”false flag” propaganda in WW II were Sefton Delmer and his PWE (Political Warfare Executive). Delmer was born and mostly raised in Berlin: his Australian father had been a professor of English literature there until he and his parents were interned as enemy aliens during WW I, then released to England in a prisoner exchange. After getting a degree in modern languages at Oxford and working as a freelance journalist, he was recruited as the Berlin bureau chief for the Daily Express (1990-1933). There, he befriended top nazis (particularly SA leader Ernst Röhm) and in fact became the first British journalist to be allowed to interview Hitler (y”sh). He was also present at the scene of the Reichstag Fire (and kept arguing all his life that it was a Nazi “false flag attack”): shortly after, he was reposted to Paris, and later reported on the Spanish civil war as well as on the invasions of Poland and France. In the nick of time, he and his wife made it to England, where he briefly worked as an announcer for the BBC German-language service.
Delmer spoke flawless German, both formal and colloquial, and was intimately familiar with German mores. These qualities came to serve him well when he was recruited by the PWE to run psychological warfare broadcasts.
After a few false starts, GS-1 or (in the German radio alphabet of the day) Gustav Siegfried Eins emerged. In modern net-speak, it was what we would nowadays call a massive “concern trolling” operation. GS-1 was a shortwave station on which “Der Chef” supposedly reached out to his network of “patriotic opposition”. Supposedly, Der Chef was an old-school senior army officer who was loyal to Germany and even to the Führer, but disgusted with the corruption and perversion of party and SS officials, which he collectively referred to as the Parteikommune. From his perch, he told tales of nest-feathering, pocket-lining, living high on the hog while troops and regular citizens suffered, as well as of sexual licentiousness, orgies. and “Violations of Paragraph 175” (i.e., homosexuality). (While a fair amount of this was written by amateur and professional pornographers, not all of this was fictional: Sefton Delmer was privy to many a dirty secret the Nazis wished he wasn’t.)
Eventually, when GS-1 had outlived its usefulness, “Der Chef”s lair was supposedly overrun, live on the air, by the Gestapo, with the broadcasts ending in bursts of sub-machinegun fire.[**]
GS-1 made way for Delmer’s greatest achievement: the creation and operation of two subtle “false flag” radio stations working in tandem: the high-powered Soldatensender Calais on the AM band, and its shortwave companion station Deutscher Kurzwellensender Atlantik (targeted primarily at German naval personnel, which by that stage primarily meant U-boot crews.)
Soldatensender Calais purported to be a German military entertainment broadcaster operating from Calais in occupied Northern France: in fact, it was being broadcast from a 500 kW (!!) station Aspidistra [*] in Southern England. Its programming consisted of what Sefton Delmer would later describe as “cover, cover, cover, dirt, dirt, cover”: a mixture of music popular with the German troops, sports coverage, and — for additional cover — speeches by Hitler and other top Nazi officials, the better to make the listeners receptive to disinformation and demoralizing propaganda items. For example, a broadcaster posting as a soldier would give tips on how to be declared unfit for onerous duty, how to avoid being transferred to the Eastern Front, etc., while others would detail scams Wehrmacht men might fall prey to, or arouse the age-old anxiety of the deployed soldier about his wife’s fidelity, his family’s welfare, or both.
The station made its last broadcast on April 30, 1945, the day Hitler committed suicide.
After the war, Delmer served as chief foreign affairs correspondent for the Daily Express for fifteen years, until forced into retirement over an expenses dispute. He would go on to write several volumes of memoirs, an archive of which can be found here.
I cannot resist mentioning that when Labour MP (and British ambassador to Moscow) Stafford Cripps found out about Delmer’s operations, he was so scandalized that he wrote to Anthony Eden (Foreign Secretary and de facto Churchill’s deputy) that “If this is the sort of thing that is needed to win the war, why, I’d rather lose it.” This is of course precisely the sort of thing that inspired Churchill’s famous quip about the ascetic Cripps: “He has all the virtues I dislike and none of the vices I admire.”
[*] This has originally been built for WJZ radio in Newark, NJ — yes, Steely Dan fans, the station namechecked in “The Nightfly” — until an FCC regulation limited individual stations’ broadcasting power to 50kw. RCA was only too happy to resell it to the British government.
