How to Win an Information War by Peter Pomarantsev review – the radio host who beat Goebbels at his own game

This compelling study of 1930s journalist Sefton Delmer reveals how he used ‘grotesque cabaret’ as propaganda to undermine the Germans’ faith in nazism – and how such methods could be used against today’s tyrants

In 1941 a secret British radio station called on Germans to rise up against Hitler. Run by German exiles, it was explicitly left wing. The station’s target audience was “the Good German”. Its broadcasts were serious and idealistic: a ray of light amid totalitarian darkness. They were also a complete flop. With Nazi propaganda rampant, and Hitler’s armies seemingly invincible and on the march across Europe, few bothered to listen in.

It was at this point that Britain’s wartime intelligence services tried a more radical approach. That summer, a talented journalist called Sefton Delmer was given the job of beating the Nazis at their own information game. Delmer spent his childhood in Berlin and spoke fluent German. In the early 1930s he chronicled Hitler’s rise to power – flying in the Führer’s plane and attending his mass rallies – as a correspondent for the Daily Express.
