The Battle of Britain holds the unusual distinction of bearing its name before a single shot was fired in anger. On the 18th of June 1940, more than three weeks prior to the generally accepted start of the campaign, Prime Minister Winston Churchill delivered a speech to the House of Commons that would define the coming struggle. He declared that what General Weygand had called the Battle of France was over, and that the Battle of Britain was about to begin. This naming was not merely a label but a psychological weapon, intended to steel the British public for a long war after the rapid collapse of their allies on the continent. The Germans had already overwhelmed France and the Low Countries, leaving Britain to face the threat of invasion by sea. Hitler and his high command believed that the British, defeated and without European allies, would quickly seek terms, yet Churchill used his rhetoric to harden public opinion against capitulation and prepare the nation for the air war that was to follow. The Luftwaffe, under Hermann Göring, was ordered to destroy the Royal Air Force to clear the way for a potential invasion, but the British had already named the conflict before the first strategic bombing raid took place on the 10th of July 1940.
The Doctrine Of The Bomber
The strategic thinking that shaped the air war was rooted in the interwar years, where the prevailing belief among military theorists was that the bomber would always get through. This doctrine, championed by figures like Giulio Douhet, suggested that air attacks on civilian targets would cause panic and lead to rapid capitulation, making the only defense a deterrent bomber force. In Germany, the Treaty of Versailles had forbidden a military air force, so aircrew were trained through civilian flying and secret schools in the Soviet Union. By 1935, the Luftwaffe was formally announced, and its doctrine prioritized the destruction of enemy armed forces over strategic bombing of industries or civilians. However, the defeat of France in 1940 introduced the prospect of independent air action against Britain, and the Luftwaffe command, led by Göring, began to shift focus. They reserved strategic bombing for stalemate situations or revenge attacks, doubting if it could be decisive on its own. Göring was convinced that strategic bombing could win objectives beyond the reach of the army and navy, and he expected air warfare to force Britain to negotiate. This mindset led to a lack of systematic focus on one type of target, such as airbases or aircraft factories, which diluted the effectiveness of the German attacks and allowed the RAF to recover and fight on.The Machine And The Man
The air war was fought with machines that were often superior in one aspect but flawed in another, creating a complex battlefield where technology and pilot skill intersected. The Luftwaffe's Messerschmitt Bf 109E was faster and had a better climb rate than the RAF's Hurricane, but it had a larger turning circle and could not engage in negative-g maneuvers without engine failure. The British fighters, equipped with eight Browning machine guns, were less effective than the German 20mm cannons, yet the RAF's radar and control systems allowed them to intercept raids with a success rate of over 75 percent. The Bf 110, a twin-engine destroyer, was too vulnerable against the nimble single-engined RAF fighters and was largely withdrawn from daylight service after suffering heavy losses. The pilots themselves were a critical factor, with the Luftwaffe drawing from a cadre of Spanish Civil War veterans who had comprehensive training in aerial gunnery. In contrast, the RAF was short of experienced pilots, with only 30 percent of its 9,000 pilots assigned to operational squadrons. The lack of trained pilots in the fighting squadrons became the greatest concern for Air Chief Marshal Hugh Dowding, commander of Fighter Command, and the problem of finding sufficient numbers of fighter pilots became acute by mid-August 1940.
