Battle of Britain. Statistical Analysis. I./1

The primary motivation for this analysis stems from a keen interest, both personal and shared by many compatriots, in the early events of the Great Patriotic War. Over the past fifteen years, numerous books and articles, including those on aviation, have explored the events of June 1941. Works by authors like Mark Solonin and Dmitry Khazanov, though vastly different in their approaches, underscore the complexity of the subject.

It seemed prudent to examine the Luftwaffe’s state by June 1941 through the prism of a well-documented air campaign: the Battle of Britain. This conflict served as a testing ground for many tactical innovations and vividly exposed both the strengths and weaknesses of the German air force. Despite significant losses, the Luftwaffe was not crippled; rather, the British effectively sharpened this instrument of the German war machine.

The Battle of Britain offers numerous examples of bold and tactically diverse actions by both Luftwaffe pilots and command. Their initial successes in the Soviet Union during the early war period, and their subsequent degradation, are understandable. This decline was largely due to a habitual underestimation of the enemy, leading to inadequate production planning and pilot training, and ultimately, an inability to sustain high activity levels over prolonged periods. This analysis aims to provide maximum statistical data, some of it original or little-known, with minimal authorial interpretation, allowing readers to draw their own conclusions. Future work will include a technical analysis of the combatants’ aircraft and a compilation of key operations and episodes.

Rethinking the Battle of Britain Narrative

British historians, for reasons known only to themselves, have often allowed the Fighter Command diaries from July 10 to October 31, 1940, to overshadow the broader air struggle in the context of the planned (but unexecuted) invasion of the British Isles. The emphasis in Britain has been on the heroism and sacrifice of “the Few”—approximately 3,000 individuals, including some 500 posthumously—who purportedly saved the nation from Nazi enslavement. This narrative suggests the British Empire urgently needed heroes, and on a scale far exceeding Soviet propaganda efforts, elevating entire commands to heroic status simply for completing a single combat sortie.

Without disparaging the brave British (and other) pilots, one must question why hundreds of undistinguished airmen, with only a few sorties and no enemy contact, became national heroes, while B. Hancock of No.6 SFTS, who rammed a He 111 with his small Avro “Anson” on August 18, is not similarly recognized. Similarly, Blenheim fighter pilots escorting naval Albacores to bomb invasion barges in French ports are deemed heroes, yet the fate of the Albacore crews remains obscure, often because they were not RAF and held different ranks, thus excluded from the Battle of Britain narrative. The same discrepancy applies to Bomber Command pilots: those who destroyed ten He 111s in Eindhoven are not celebrated or counted in canonical loss figures, while downed German aircraft and pilots are meticulously listed.

It is known that after the exaggerated figures of German losses claimed by the British, and the increasing skepticism from neutral press regarding British reports, Churchill personally halted Fighter Command RAF’s (Dowding’s) attempts to establish the true extent of Luftwaffe losses. He famously declared that it was impossible to know how many Germans crashed into the sea or in France, and he subsequently popularized the phrase “the few” in his August 20 speech. While Churchill undoubtedly acted strategically, this raises questions about historical accuracy and the memory of other unsung defenders of Britain.

A straightforward measure of combat intensity is the percentage of aircraft shot down relative to the number of sorties. By this logic, the “bloody” Battle of Britain should rank among the more intense engagements of World War II. However, FC RAF pilots flew 12,900 sorties from July 10-31, with only 0.54% losses. During the peak in August and September, they flew 38,800 sorties, incurring 1.86% losses—a level considered frankly insignificant by later Allied standards.

In comparison, Reich Air Defense pilots from March to May 1944 flew 13,607 sorties and lost 1,256 aircraft (9.23%), with 765 pilots killed. They claimed at least 1,438 confirmed kills. This stark contrast suggests either the Germans flew five times fewer sorties for similar losses in 1944, or the British flew excessively and ineffectively in 1940, despite their advanced radar systems. The common narrative that the numerically superior Luftwaffe failed due to indiscriminate targeting and British heroism, with the shift to London bombing saving Britain but dooming the Luftwaffe, is often emphasized.

German Ambitions: Eastward Bound

Unlike the Russians in the famous song, Hitler certainly desired war—a swift, victorious one to launch another. However, his primary target was not England but Russia. The truth is that Germany did not consider England a real adversary; even during the French campaign, no plans were developed for further military actions against Britain. As early as May 20, 1940, after occupying Abbeville, Hitler declared his readiness to sign a separate peace with England at any time. Subsequently, on June 2, he informed Army Group A Commander Rundstedt that if England sought peace and agreed to a “reasonable” settlement, he would be free to pursue his true major objective: the fight against Bolshevism. This “peaceful” stance from Hitler appears unprecedented in the history of World War II.

A series of events in June 1940 solidified Hitler’s resolve for a military campaign against the USSR, including diplomatic notes to the Baltic states on June 14/16 and, particularly, the resolution of the “Bessarabian question” on June 23-28. Following France’s surrender on June 22, Hitler initially prohibited Luftwaffe flights over Britain to avoid provocation. Göring permitted engagement with British aircraft over the Channel but forbade crossing it. By July 3, Franz Halder’s diary recorded the General Staff’s operational priorities: alongside Britain, the “Eastern problem” had taken precedence. Russia was firmly integrated into German military plans, under Hitler’s direct and repeated instructions.

On July 13, a meeting of the supreme military leadership concluded that England would not pursue peace, trusting instead in Russia. Britain’s stance, at first glance, was also unparalleled in WWII. Having avoided military confrontation, Britain had sequentially conceded Austria, Czechoslovakia, and Poland. In France, they fought for less than half the campaign, prioritizing the salvage of assets and evacuation of troops, even denying air support at a critical juncture. No one would have condemned England for negotiating with Hitler again.

Churchill and many others harbored a long-standing desire for a conflict between “Bolsheviks and Nazis.” A peace treaty with Hitler, akin to Stalin’s pact with Germany, would have allowed England to breathe a year earlier, save tens of thousands of lives, and shift the war eastward. Joachim von Ribbentrop’s memoirs illuminate England’s behavior: Nazi policy anticipated a series of conflicts with Eastern neighbors over lost territories, then with France. England’s centuries-old position, however, was to prevent any single European power from becoming overly dominant. Therefore, Eden’s rejection in November 1937 of a semi-official offer for the British Empire to join the Anti-Comintern Pact, fundamentally anti-Russian, becomes clear. Ribbentrop’s 1938 memorandum (A5522) further concluded that once conflicts with Eastern neighbors began, England would inevitably enter the war, drawing France in as well.

Ultimately, Directive No. 16, cautiously mentioning the “Seelöwe” invasion plan, was issued on July 16. On July 19, Hitler addressed London with a “final appeal to reason,” still hoping for a compromise peace. Yet, without waiting for a reply, he convened OKL and OKM leaders on July 21, asserting that the invasion threat was the best way to compel Britain to reason, but a real invasion would only occur if other options failed. The next day, Göring received instructions for the Eastern campaign, and Halifax delivered a frosty rejection of Hitler’s offer. A July 28 memorandum decreed continued struggle against Britain (shipping), strong air support for a swift Russian campaign, and preparations for “Seelöwe” and the Russian invasion until spring 1941. The idea of invading Russia as early as autumn 1940 was even floated. By July 31, Hitler informed his generals of the impending war with Russia, with a potential England landing set for September 20-26 (preparations to be complete by September 15). Many present understood no invasion would happen that year.

The OKW issued a directive on August 1, stating that the decision on the invasion’s feasibility would be made by the Führer 8-14 days after the air offensive against England began, approximately August 5. That same day, Hitler issued his own Directive No. 17 on the war against England, also mentioning a full-scale air offensive after August 5, with the exact date determined by the Luftwaffe’s readiness. Göring met his commanders in The Hague, and on August 2, an OKL directive ordered “Adler Tag” to begin on August 10. Due to weather, the official start was August 13, though intense aerial activity began on August 11. Dennis Richards and others cite August 12 as the start of the Battle of Britain.

Despite the September 15 deadline for “Seelöwe” preparations, Hitler declared on August 14 that invasion preparations should continue even if the invasion itself wasn’t executed. The goal remained to compel England to negotiate through air attacks and the visible threat of invasion. Meanwhile, the “Vienna Arbitration” on Romania on August 30 intensified Soviet-German tensions. On September 2, the navy requested postponing S-Tag to September 21, and Germans decided to commence bombing targets in London (not yet residential areas).

By September 11, with the invasion decision pending for September 21, the bombing results in London appeared so promising that German leadership considered an invasion unnecessary. A September 14 meeting resolved to maintain maximum pressure on England through London bombings and the demonstration of invasion intent. Göring’s request to bomb residential areas was refused by Hitler, who feared retaliation against German cities. The largest daytime raid on London occurred on September 15. In Britain, this day is often portrayed as a decisive Luftwaffe defeat, forcing Germans to abandon the invasion after reportedly losing 185 aircraft at a 1:7 ratio.

In reality, losses were more typical: 26 British aircraft versus 58 German. While the Germans aimed to demonstrate British helplessness through mass bombing, the British government, by claiming victory (even if illusory), showed its resolve to continue fighting despite potential destruction. This destroyed Hitler’s hopes of coercing England into peace through bombing or invasion threats. Consequently, at a meeting on September 17, it was decided to defer the invasion indefinitely. To protect invasion craft from Bomber Command raids, Hitler ordered their dispersal to distant ports, though with the capability to reassemble them within ten days. British photo reconnaissance confirmed this dispersal by September 23, noting a 30% reduction in concentrated barges. Churchill was aware of this as early as September 17 through “Ultra” intercepts indicating Luftwaffe’s scaling back of invasion transport. The invasion threat had passed.

On September 26, German leadership determined future military efforts would focus on the Mediterranean, Balkans, and Russia (German units had appeared in Finland on September 22). The Tripartite Pact was signed the next day, September 27. The official decision to abandon the invasion was made on October 2, and on October 12, troops were notified of its postponement until spring 1941. A month later, the Molotov-Hitler meeting in Berlin on November 12, 1940, suggested that the USSR should have immediately begun mobilization. The Germans themselves, after the war, cited weak naval forces, preparations for war with Russia, and events in the Mediterranean/Balkans as the main reasons for abandoning the invasion. While weather also played a role, it was unlikely primary, as the Allies later invaded in bad weather.

Thus, it can be argued that the impending war with Russia prevented a German landing on the British Isles. The Germans believed they could have seized beachheads despite losses, but resupply and heavy equipment would have incurred enormous casualties for the Luftwaffe. If Hitler hadn’t focused on Russia, Germans might have been willing to sacrifice dozens of divisions and the Luftwaffe, even using training aircraft. However, facing firm British resolve, Hitler realized a Blitzkrieg in Britain was impossible; they would likely have stalled at London’s outskirts. Subsequently, aid from Dominions and, crucially, the US (even without invasion, Roosevelt pushed Lend-Lease) would have become decisive. Therefore, the USSR’s “active” stance in Eastern European affairs in summer 1940 helped England avoid invasion, while the British government’s uncompromising position, particularly Churchill’s, gave Stalin almost a year to prepare for German aggression.

Comparative Air Strengths and Strategic Implications

Following the “Operation Dynamo” evacuation from Dunkirk, the FC RAF had 367 serviceable Hurricane and Spitfire aircraft on June 4, 1940. Due to high production rates, which greatly exceeded losses, FC RAF fully recovered by July 1, with 546 modern serviceable machines in squadrons. Despite some discrepancies in figures across various sources, the overall picture suggests a robust and rapidly recovering British fighter force.

The RAF maintained its aircraft in four key structures: combat squadrons, repair units, storage units (ASU), and operational training units. Daily reports meticulously tracked aircraft status. After Dunkirk, reserve fighter numbers significantly increased; by July 5, reserves in ASU had grown to 373 aircraft. Throughout the Battle of Britain, FC RAF never faced equipment shortages. Production and repair processes were exemplary, with losses consistently offset by new aircraft production and repairs. Even during peak intensity, the Luftwaffe only managed to reduce the stock of immediately available fighters (Cat.1) by 60%.

By the end of September, FC RAF held a clear numerical superiority over German fighter units, boasting 1,050 Spitfires and Hurricanes (730 serviceable) plus 300-400 aircraft in reserve, compared to 730 German Bf 109s (both serviceable and unserviceable) with no reserves. British aircraft production, particularly after the “Harrogate programme” in January 1940, significantly outpaced German output. From June to October 1940, 2,354 fighters were produced in Britain, including approximately 2,100 Spitfires and Hurricanes, totaling 4,283 for the entire year. While some American aircraft were supplied, their numbers were comparatively small (<15%) and did not critically impact the Battle, with only the Grumman “Martlet” participating marginally.

In contrast, Luftwaffe equipment availability showed a net decrease of 862 aircraft from May 10 to August 26, 1940, with total serviceable aircraft falling from 4,894 to 4,032. Fighter strength (Bf 109 and Bf 110) declined from 1,618 to 1,253 in the same period. While Bf 109 numbers decreased by a quarter, and serviceable machines by a third, over three weeks of intense combat, the primary issue for the Jagdwaffe was often a shortage of pilots rather than aircraft. For instance, in late September, I./JG 3 had 30 serviceable Bf 109s but only 18 pilots, with no replacements for those lost.

The dive bomber (Ju 87 Stuka) force, critical for invasion support, initially had 428 aircraft by July 21, 1940, with 335 serviceable. Despite heavy losses in some areas, the Ju 87 groups were quickly withdrawn from direct engagement with the RAF after “Adler Tag,” primarily due to their high value rather than insurmountable losses. By mid-September, the Luftwaffe still possessed approximately 500 Ju 87s. However, German aircraft production in 1940 was significantly lower than Britain’s. For example, from July to October 1940, Germany produced 688 Bf 109 fighters, compared to Britain’s 2,116 single-engine fighters (including imports), a ratio of 3.08:1 in Britain’s favor.

In conclusion, Churchill’s government pursued a deliberate policy of war escalation from May 1940, driven by Britain’s fundamental opposition to any single European power achieving dominance, rather than purely Nazi ideology. Preparations against a potential German invasion began early, even before Germany had firm plans. By July 1940, British aviation industry was demonstrably more powerful, holding a triple superiority in single-engine fighters and facing no pilot shortages. This raises the question of how Germany, facing such a disadvantage, expected to win, a topic to be explored in future analyses. Ultimately, the robust and adaptable British air defense, coupled with Hitler’s strategic shift towards Russia, proved decisive in averting Operation Seelöwe.
