Humour is a vital ingredient for the morale of a nation at war. From the John Bull cartoons mocking a hook-nosed Napoleon carving up the world, the caricatures of an obese Kaiser in the First World War, to an often angry Hitler, cartoons have not only portrayed the enemy in a satirical light but have raised a smile in the darkest of times. Self-depreciating humour is also a facet of cartoons during wartime – making fun of incumbent politicians and incompetent generals – while at the same time challenging the decisions of those in powerful positions in a manner meant to embarrass. Indeed, cartoons often carry a serious message which exemplifies the subject far more impactfully than the written word. It is also the case that cartoons can broach subjects too sensitive to be touched upon in editorials or by columnists. Such is the case with this absorbing, if light-hearted view of the Second World War portraying the seismic events of the conflict in a fashion which everyone at the time could understand and nod their appreciation to with a smile on their lips. The Second World War in Cartoons begins in the 1930s with events in Germany and the Rhineland and the slow march to war. This is followed by the inevitable references to the Phoney War and to Hitler’s ‘Sink-on-Sight Navy’ after the Graf Speen had been scuttled by her captain. A more serious tone is undertaken during Britain’s darkest hour, the cartoons reflecting Churchill’s stubborn determination to resist and encouraging the fighter boys to stop Hitler. Gradually, the mood changes as the UK’s strategic position improves. When the war ended in Europe, a cartoon of Germany depicts a notice ‘Under New Management’. Churchill’s defeat in the 1945 election resulted in one cartoonist declaring that Britain had ‘dropped its pilot’ and, ever a cartoonist favourite character, among the final images is that of Churchill declaring an Iron Curtain had descended across the Continent, as the Cold War took its grip. Each of these wonderful cartoons is provided with a full explanation of the background to each one, and its relevant to the events of the day.
