The Big Wing, also known as a Balbo, was an air fighting tactic proposed during the Battle of Britain by 12 Group commander Air Vice-Marshal Trafford Leigh-Mallory and Acting Squadron Leader Douglas Bader. In essence, the tactic involved meeting incoming Luftwaffe bombing raids in strength with a wing-sized formation of three to five squadrons. In the Battle, this tactic was employed by the Duxford Wing, under Bader's command.
Big Wing vs Park's approach[edit | edit source]
The Big Wing contrasted with the tactics used by Air Vice-Marshal Keith Park, the commanding officer of Fighter Command's 11 Group, which was taking the brunt of the Luftwaffe attacks. Park met the raids with individual squadrons, which he considered to be the most flexible and effective use of his aircraft, particularly in light of the shallow depth of penetration of Britain's airspace by the Germans. He used "hit and run" tactics with an enemy raid potentially being engaged by several squadrons in turn. The tactic had been questioned by many of Park's subordinates, who were appalled by the high loss rates amongst the squadrons of 11 Group. In this battle of attrition they wanted to employ larger formations to provide mutual protection and reduce casualties.
By contrast, Leigh-Mallory, the commander of the neighbouring 12 Group to the north, was a powerful advocate of the Big Wing policy, causing enormous friction in his working relationship with Park. One of Leigh-Mallory's subordinates was the acting leader of 242 (Canadian) Squadron RAF, Douglas Bader, who had flown as part of Keith Park's own Big Wings over Dunkirk just a few weeks earlier. Experience covering the French beaches against air attack had convinced Bader that large formations were essential and with Leigh-Mallory's blessing a special wing was formed at RAF Duxford to try to prove the Big Wing theory. Supported by Duxford station commander Group Captain 'Woody' Woodhall, Baders' 'wing' theory was developed over the next few days, and initially involved three squadrons, No. 242 and No. 310 (Czech) flying Hawker Hurricanes and No. 19 Squadron RAF (based at nearby RAF Fowlmere) flying Supermarine Spitfires.
On 7 September 1940, the "Big Wing" was scrambled operationally for the first time, to patrol North Weald, but the formation arrived late. Bader acknowledged the fact that they were too slow forming up and for the flight to the patrol area the formation was too disjointed. Nevertheless the "Big Wing" claimed 11 enemy aircraft destroyed for the loss of one fighter. Over a number of days in September 1940, the wing was sent up to try to disrupt the Luftwaffe raiders. The Duxford Big Wing was not an organised and rehearsed military unit, merely an ad-hoc collection of squadrons led by one of Fighter Command's less experienced squadron leaders. Between Leigh-Mallory and Bader there was no planning on how to use a Big Wing nor an assessment of its achievements. On 9 September two more squadrons, the Hurricanes of No 302 (Polish) and the Spitfires of No. 611 Squadron RAF, were allocated to the "Big Wing" and again Park requested protection of the 11 Group airfields. The result was practically a carbon copy of 7 September. Park himself had experimented with large wings (covering the earlier Dunkirk evacuation) and insisted that they were unwieldy, difficult to manoeuvre into position, and rarely in the right place when needed. 11 Group was closer to the enemy than 12 Group, and Park pointed out that there was insufficient time available over Kent and Sussex for a large formation to gain crucial altitude against the incoming raids. Bader countered by pointing out that his wing could be used as a reserve for 11 Group. Positioned well away from the Luftwaffe bases in France he could be in place at altitude when the wing was needed, providing adequate early warning was given. Air Chief Marshal Sir Hugh Dowding, commanding officer of RAF Fighter Command, had put a huge amount of effort into developing the world's first complete air defence system incorporating the Chain Home radar stations, Royal Observer Corps ground observation posts, telecommunications and information processing. The best early warning possible was provided to 12 Group. Bader further delayed deployment of 12 Group fighters by insisting he lead the Big Wing, in order to do this he had to fly 242 Squadron to Duxford from RAF Coltishall every day. Bader wanted time in order to fly to Duxford, land, take-off again then form a Big Wing, the amount of early warning required for this was extremely unrealistic. The Duxford Big Wing was also a mix of Hurricane and Spitfire squadrons, the Spitfires were thus delayed as they had to fly and climb at the same speed as the slower Hurricanes. Bader did not always follow ground control instructions and often flew into 11 Group's area on his own inititative. In order for such a large formation to be successful, not only should it be well planned and rehearsed, but its leadership had to be disciplined within Fighter Command's overall battle plan. That was blatantly disregarded. If Leigh-Mallory had a vested interest in the Big Wing then he had a responsibility to make sure that at least it was organised properly. This clash of opinions between the 11 and 12 Group commanders was left unresolved by Leigh-Mallory and Park's commander, Dowding. Subsequent events, in which Dowding retired from his post at Fighter Command and Leigh-Mallory was promoted to command Keith Park's group, show that Leigh-Mallory's arguments had the sympathies of the senior echelons of the RAF. These sympathies could have been due to tensions between these senior RAF officers and Dowding rather than any thought on how Britain could be most effectively defended. In Spitfire: Portrait of a Legend, Leo McKinstry cites sources saying that Dowding was widely criticised after the Battle in RAF reviews of his strategy for keeping the control of 11 and 12 Group resources separate under Park and Leigh-Mallory, instead of uniting them under one command or at least coordinating them as one Group. The effect of this decision was a lack of coordination between 11 and 12 Groups which often meant the aircraft of 11 Group were fully committed, while those of 12 Group sat idle. A letter by Park in 1968, quoted by McKinstry, illustrates the problem:
|“||Throughout August and September 1940, on occasion when all my squadrons had been dispatched to engage the many German bomber forces, I called on No 10 Group to cover some vital targets on my right with one or two squadrons. Brand always responded at once and on many occasions effectively intercepted the enemy, preventing them from bombing their target unmolested. In similar circumstances I called on No 12 Group to cover my fighter aerodromes northeast and east of London but Leigh-Mallory failed to respond. This resulted in North Weald, Hornchurch, and Debden being accurately bombed whilst 12 Group wing was being dispatched, assembled and climbed in mass formation to the rear of my area.||”|
According to McInstry in another letter Park wrote at the time he said, "Frankly I was more worried at the lack of cooperation (with Leigh-Mallory), than I was about out-witting the massed German raids."
What has been described as an "even-handed" assessment of the affair was published in the Air Ministry's Air Historical Branch history, written shortly after the battle: "[T]he pity is that a controversy was ever allowed to develop; for far from the two Group commanders representing two contrasting methods of solving one and the same tactical problem they really represented tactics complementary to each other, each of which had a valuable part to play in the common struggle, the more so as together the most economical use of the dangerously limited forces available would have been assured." (Note that this assessment is according to the Air Ministry of which the most senior individuals were involved in using the Big Wing theory as the means to conspire against Dowding. Given this and the personal animosity towards Dowding the Air Ministry view of the Battle of Britain cannot be said to be "even-handed". As first published by the Air Ministry there was no mention of Dowding or Park, it was withdrawn and revised at Winston Churchill's insistence)
Further evidence of this conflict can also be seen in a memo, again cited by McKinstry, which Leigh-Mallory sent to Park during the Battle, "Full explanation required why 11 Group fighters have shot down enemy fighters over 12 Group area." This is more than a little ironic given that 12 Group was expected to bolster defence in 11 Group's area (by shooting enemy planes down) but instead a Big Wing was sent, often to the wrong place causing more disruption to 11 Group's well thought-out plans than to the enemy.
Did the Big Wing work?[edit | edit source]
After the Battle of Britain Leigh-Mallory never really had a chance to use the Big Wing defensively again. The Big Wing quickly mutated from a defensive to an offensive formation, Douglas Bader would eventually lead one of these new wings on massive fighter sweeps over France. To this day there is debate over the effectiveness of the 'Big Wing' as it was used during the Battle. On the one hand, although Leigh-Mallory and Bader claimed it was a great success, post-war analysis suggests the actual number of German aircraft shot down by the wing was probably a fraction of those claimed (The claims for the Big Wing were never credible even at the time. Some senior people like Leigh-Mallory and Sholto Douglas wanted to believe these claims so that they could use the Big Wing as a political tool against Dowding). This would seem to support the idea that, for a 'Big Wing', there were "not enough enemy to go around". In other words, the Wing had too high a concentration of aircraft in the same air space looking for targets.
It could be argued that 12 Group had more time to get fighters into position but even then it failed to do so. As a consequence when 11 Group was stretched to its limits and required support, due to the delay imposed by 12 Group, 11 Group airfields were left undefended. This was due not only to time wasted in forming up the big wing but also due to 12 Group commanders not following 11 Group's instructions and arriving in the wrong place. Not only did 12 Group fail to support 11 Group they left their own airfields undefended, a large portion of UK airspace was left undefended while Leigh-Mallory and Bader tested their Big Wing theory. The time taken to form a big wing also wasted fuel and combined with the limited range of the fighters reduced time over the combat zone. When 10 Group was asked to provide cover for 11 Group in similar circumstances it was provided and the relevant 11 Group airfields were defended.
On the other hand, casualties for the 'Big Wing' were significantly lower than in the smaller formations - suggesting that they did indeed benefit from protection in numbers. The 'Big Wing' invariably joined combat with the enemy over Northern London, where the German fighter escort was at the very limit of its range and therefore effectiveness. The Big Wing also made very few interceptions, as a result lower casualties would be expected - on both sides. Certainly Park's tactics (which had included the occasional use of two and three-squadron wings) were correct for the conditions he had to fight under. The most powerful argument against the Big Wing's use in the Battle of Britain is that without a clear idea of a raid's target as it assembled over France, it was impossible for the Big Wing to get airborne and form up in time to meet the enemy.
Another argument against the use of the Duxford Big Wing was that it was never a serious tactical proposition. It was formed after a telephone discussion between Leigh Mallory and Bader, there was no planning, protocols for its operation nor discussion (let alone agreement) within Fighter Command. Leigh-Mallory did not question Bader's claims nor critically assess the Big Wing's results. For a senior commander to take the word of an inexperienced junior officer and commit to such a poorly planned experiment at a critical time is very questionable.
The successful interceptions by the Big Wing only occurred over a short period of time in September when the Luftwaffe switched from military targets and airfields to daylight raids on London. The Luftwaffe bombers were at their most vulnerable when they were at the limit of the escorting Bf 109's range and many German fighters had already expended their fuel in combat with 11 Group aircraft over Kent. When encountered by the Luftwaffe on 15 September the Big Wing had a psychological impact. Having been told that the RAF was down to its last 50 fighters by their leaders the Luftwaffe aircrew were continuously attacked on the run over Kent only to be confronted by a further formation of 60 RAF aircraft over London just as their escort reached the limit of their range. One reason for this level of surprise was that a recent large Luftwaffe fighter-only sweep had encountered little resistance, confirming the Luftwaffe leaders' belief that there were few RAF fighters left; in fact Park had recognised this fighter sweep as a ruse to get his fighters into the air, but with no threat of bombing he had kept his fighters on the ground on this occasion. While not effective as a fighting tactic the Big Wing, along with some blatant manipulation of statistics, worked as a political tool for those against Dowding. Dowding had clashed with Hugh Trenchard (founder of the RAF) while both were RFC commanders during World War I. Hugh Trenchard was retired by World War II but was a Marshall of the RAF and still had heavy influence at the highest level in the RAF. He supported the theory of the "knock out blow" where air attack was fought by counter attack with bombers, not defence by fighters, and this view was shared by many senior RAF and Air Ministry people. Despite this RAF policy Dowding got enough political support to build up Fighter Command into a very effective weapon, the weapon that won the Battle of Britain. In 1940 (and arguably the whole war) Bomber Command was in no way capable of delivering a knock out blow to Germany so the pro bomber advocates were severely embarrassed by Fighter Command's success. Hugh Dowding's "stuffy" personality and unwillingness to fight this political battle also contributed to his downfall. The Big Wing debacle was merely a smokescreen manipulated by his political enemies to bring him down. It is understandable that Dowding did not fight back given the stress he had been under for the best part of a year, first to conserve Fighter Command then to oversee the long battle of attrition against the Luftwaffe.
A 'Big Wing' exercise[edit | edit source]
The use of a 'Big Wing' within 11 Group was explored by Fighter Command in paper exercises run by Leigh-Mallory in January 1941. The intention was to prove the superiority of large formations using the circumstances of an actual attack on Kenley, Biggin Hill and Hornchurch sectors on 6 September 1940. In the event Leigh-Mallory completely mismanaged the operation, permitting the raid to progress unhindered and resulting in Kenley and Biggin Hill airbases being 'bombed' while their aircraft were still on the ground. One of Park's former controllers explained Leigh-Mallory's mistakes to him. He replied that he would do better next time and that if a large-scale raid approached he would permit it to bomb its target and intercept it in force on its return to France. The enemy, he believed, would be so badly mauled that there would be no more raids.
