In 2020, From Balloons to Drones will run a series of articles that examine the use and development of air strikes from the earliest use of air power through to today.
The use of air power to achieve an effect on the ground and at sea remains controversial. For example, with regards to strategic bombing, Robert Pape argued in Bombing to Win that it ‘did not work’ as a military strategy. Moreover, since the inception of air power, there have been ongoing legal and ethical debates about the use of air strikes in various spheres of military activity. As such, From Balloons to Drones is seeking submissions for a series of articles that examine the varied use of air strikes, both kinetic and non-kinetic, at the tactical, operational and strategic levels of war. Themes to be explored might include, but are not limited to:
Strategy, Theory and Doctrine| Organisation and Policy | Roles
Operations – Kinetic and Non-Kinetic | Tactics, Training and Procedures
Strategic and Operational Effect | Technological Developments
Culture | Ethical and Moral Issues
National, International and Transnational Experiences
We are looking for articles of c. 3,000 words, though we will accept larger pieces and we reserve the right to publish them in parts. We welcome and encourage submissions from academics, policymakers, service personnel, and relevant professionals. We also welcome submissions written from diverse academic disciplines.
We plan to begin running the series in January 2020, and it will continue for as long as we receive potential contributions. We will also be looking at publishing extended versions of selected articles in an edited volume.
Submissions should be submitted in Word format and emailed to the address below with ‘SUBMISSION – Bombing to Win Revisited’ in the subject line. Also, please include a 50-100-word biography with your submission. Footnotes can be used, and please be careful to explain any jargon. However, if you are not sure if your idea fits our requirements, then please email us with ‘POTENTIAL SUBMISSION – Bombing to Win Revisited’ in the subject line to discuss.

Editorial Note: The 4th of July 2018 represented that 100th Anniversary of the Battle of Le Hamel. While Hamel was important, its place as a model on which subsequent operations were based has been overplayed. Furthermore, notable popular Australian historians have also distorted the significance of the battle. Nevertheless, as Dr Michael Molkentin highlights in this article, Hamel was valuable in highlighting the evolution of, and the diverse roles played by, air power in support of land battles during the First World War.
In the historiography of the First World War, the Battle of Hamel (4 July 1918) has frequently been cited as an example of significant tactical innovation and a ‘model’ on which subsequent British offensive operations were planned. While neither interpretation bears up to scrutiny when the battle is viewed within the broader context of British Army operations on the Western Front, relative to its size the Australian Corps’ capture of Hamel integrated air power to a hitherto unprecedented extent and, in hindsight, provides a revealing case study of the varied, distinct and specialist air power roles that had evolved during the conflict.
The Australian Corps’ headquarters, commanded by the recently appointed Lieutenant-General Sir John Monash, planned the capture of the village of Hamel (located south of the Somme) as a line-straightening operation. Besides the troops of his own corps’ 4th Division, Monash had ten infantry companies from the US 33rd Division, 60 tanks from the British 5th Tank Brigade (including the new Mark V tank) and 639 artillery pieces. Monash planned to launch a surprise assault behind a creeping barrage and tank screen (much like British Third Army had done at Cambrai the previous November); he anticipated that his infantry could secure their objectives – two kilometres deep on a seven-kilometre wide front – within an hour and a half.
Monash’s staff also worked with the Royal Air Force’s (RAF) V Brigade to organise substantial and multi-layered air support for the operation. The Australian Corps’ corps squadron, No. 3 Squadron Australian Flying Corps (AFC), would conduct the ‘majority of the tactical work’ during the battle. Its airmen would maintain a continuous presence over and directly beyond the battlefield to follow the progress of the Australian infantry (contact patrols), watch for enemy counter-attacks (counter-attack patrols), identify and direct artillery fire onto active German batteries (artillery patrols) and to photograph the new front line once it had been secured. New maps would then be produced and issued to troops in the front line within a matter of hours. Assisting No. 3 Squadron with providing tactical air support, the RAF’s No. 8 Squadron would co-operate with the tanks while No. 9 Squadron parachuted ammunition to troops at their objectives. The night-bombers of No. 101 Squadron flew above the staging area on the night before the battle to mask the noise of the tanks as they moved up to their starting line.
The squadrons of 22nd (Army) Wing were also assigned to support the land battle: three of its four fighter squadrons would fly ground-attack sorties while its Bristol Fighter unit watched roads, railways and debussing points as far east as Proyart (10 kilometres east of Hamel). The army wing’s two bomber squadrons would meanwhile raid known German bivouacs. This aspect of the air plan reflected the RAF’s preference for interdiction over ‘trench strafing’ – the belief being that it was better to harass German troops and artillery behind rather than on the battlefield itself. GHQ allocated three additional fighter squadrons from, IX Brigade, the RAF’s strategic reserve, to provide air superiority and the neighbouring Third Army’s fighters extended their offensive patrols south to cover the rest of Fourth Army’s front.
Probably no other division-sized operation of the war enjoyed the combined support of aircraft from three wings, that is, 13 squadrons, or 230-odd aircraft. As well as the multi-faceted and highly integrated function that air power had assumed by this stage, the air plan, devised by the Australian Corps’ BGGS in collaboration with V Brigade illustrates the British Army’s growing reliance on machinery and firepower to reduce casualties and compensate for dwindling manpower.
As the plan dispensed with a preliminary bombardment, No. 3 Squadron’s artillery spotting began at zero hour. For the first few hours, airmen reported batteries neutralised by the barrage so that artillery commanders could switch their guns onto active targets. The plan also allocated five heavy batteries to answer zone calls, airmen being briefed on where the Germans might move batteries once the battle started. No. 3 Squadron issued 80 zone calls and co-operated in the neutralisation of at least 17 batteries (‘in many cases’ airmen did not see the artillery’s response to zone calls). Although not entirely preventing it, the Australian Corps counter-battery arrangements suppressed the German artillery’s response adequately during the advance and consolidation.
Counter-attack patrols flew beyond the German lines to ‘an unheard of distance’ with instructions to transmit zone calls on concentrations of German troops and engage them with bombs and machine guns. One crew reported a concentration of enemy infantry just before 0700 but otherwise, seeing no enemy counter-attacks the airmen, as Lieutenant Arthur Barrett put it, ‘bombed and machine gunned everything we saw.’ Crossing the line just after zero hour he and his pilot halted a train, silenced several machine gun positions and strafed a pair of limbered guns, overturning one. Descending below 300 feet, Barrett’s eyes ran from gas in the barrage. 3rd Squadron’s airmen dropped 138 bombs and fired 9,500 rounds on 4 July 1918. Combined with the record 54,000 rounds and 850 bombs expended by 22nd Wing’s fighter pilots, this had a considerable impact on such a narrow battlefront. ‘Several’ prisoners attested to the ‘moral effect’ of air attacks and noted how:
[t]hey prevent men getting machine guns into action almost as effectively as a barrage […] it was almost impossible to look over the top without getting machine gunned from the air.
Corroborating this is German Second Army orders that noted ‘heavy casualties caused by machine gun fire from low-flying enemy machines’ at Hamel and issued instructions for dealing with British aircraft.
Although Australian infantry had been signalling to aircraft since operations at Poziéres in 1916, contact patrols represented a new role for 3rd Squadron at Hamel. Despite difficulties experienced during the 1916-17 campaigns, the general staff recognised that aircraft provided the shortest possible passage of information from the battlefield to corps (and, atypically at Hamel, divisional) headquarters. Dropped by airmen returning from the line, contact patrol reports reached headquarters staff in 24 minutes on average – up to half the time taken by a wireless message and a third of that usually taken by carrier pigeon. Experience indicated that staff needed to synchronise contact patrols with the infantry’s timetable carefully. At Hamel, No. 3 Squadron had instructions to call for flares on the objective at 90 minutes after zero. No. 8 Squadron followed the tanks across the battlefield and ‘in one or two cases were able to give information as to those which had been put out of action.’ The infantry’s clockwork progress and minimal resistance at the objective allowed the infantry and tanks to respond ‘well’ when contact patrol pilots sounded their klaxon horns; the airmen delivered ‘exceedingly accurate’ reports. It remained to be seen, however, how the system would cope during running battles and exploitation operations when it would be arguably more crucial for staff to keep track of their troops.
For the first time, at Hamel, the RAF organised battlefield resupply using equipment designed and built at No. 3 Squadron’s aerodrome under the direction of ‘B’ Flight’s commander, Captain Lawrence Wackett. The idea apparently came from the Luftstreitkräfte’s (German Air Service) attempts at dropping ammunition to troops on the battlefield during the spring offensives. At Hamel a detachment from No. 9 Squadron carried out the work, dropping 111,600 rounds to Australian troops at their objectives and at dropping stations close behind the line. Endorsing Wackett’s claim for a £1,000 inventor’s fee from the British government (he received £350), Monash declared the scheme ‘an unqualified success’, noting how it permitted the rapid resupply of troops in ‘isolated and exposed positions’ and saved casualties among carrying parties. His subordinates, though more prosaic, also indicated the trial’s success. 4th Australian Infantry Brigade’s CO described it as working ‘satisfactorily’ while 6th Brigade’s commander noted how the scheme ‘worked very well,’ delivering ammunition within 10 yards of one machine gun position. Though faster, aircraft lacked the carrying capacity of other transportation available to the Australian Corps: a single tank could deliver four times as much ammunition as each of No. 9 Squadron’s aircraft, plus 300 grenades, 450 litres of water and a vast quantity of food and other trench stores. Employed in all subsequent British offensives (the RAF delivered 30-60,000 rounds each day during the Amiens offensive), ammunition drops by corps squadrons thus remained an ‘emergency’ adjunct to other forms of battlefield logistics.
The RAF’s tactical support was enabled, to a substantial extent, by the air superiority that British airmen exercised over the battlefield. Throughout the day, the fighter squadrons of 22nd (Army) Wing and three additional fighter squadrons attached from IX Brigade, ranged east of the battlefield to intercept any German aircraft that attempted to interfere. It was RAF policy to employ air superiority patrols offensively, east of the lines, rather than as a protective screen or close escorts. The airmen of the Luftstreitkräfte made no sorties over the Hamel battlefield until 9.30am – some five hours after the Australian infantry had secured their objective line. German fighters after that became ‘fairly active’ over the area, and there were ten air-to-air combats. In the largest of these, the SE5as of No. 24 Squadron engaged a mixed formation of 20 Fokker DVIIs, Pfalz scouts and Albatros DVs over Cerisy, six kilometres east of Hamel. The British pilots claimed three enemy aircraft and lost none themselves. It is noteworthy that No. 24 Squadron was one of the 22nd (Army) Wing fighter units allocated to bomb and strafe targets on the ground behind German lines – its involvement in this dogfight illustrates the integration of air superiority and interdiction roles that British airmen had begun to undertake at Third Ypres the previous year.
Altogether, of the hundreds of sorties flown by the RAF in support of the Hamel operation, only three resulted in the loss of an aircraft to air combat– and only one of these involved one of the aircraft involved in direct tactical support over the battlefield. All other British losses resulted from ground fire, to which the pilots of low-altitude contact patrols and ammunition drops, were considered vulnerable. The RAF’s efforts to maintain air superiority, therefore, appear to have been overwhelmingly successful – although the woeful deficiencies in material (especially fuel) that the Luftstreitkräfte faced in the summer of 1918 need to be recognised when evaluating the success of the British air plan.
The Battle of Hamel, therefore, indicates the extent and sophistication to which the application of British air power in support of surface operations had evolved during the First World War. The efforts of British airmen to support of Monash’s troops were not only extensive but organised carefully, through a variety of distinct air power roles, to provide a range of tactical and operational-level services that, considering the aircrafts’ technical limitations, functioned effectively. Indeed, the operation represented the high-water mark of efficacy in air-ground cooperation in the British Expeditionary Force during the First World War. As a limited, set-piece battle, Hamel drew on structures, procedures and technologies that had evolved during four years of trench warfare. Subsequent British operations during the ‘Hundred Days’, in which exploitation and pursuit replaced carefully planned set pieces, would test this system of integrating air power with surface forces and in some respects undermine the efficacy of British close air support. The war’s final battles would, in some respects, force airmen to begin their ‘learning curve’ all over again.

Jonathan Bailey wrote that the First World War was the time of a true revolution in military affairs about the development of artillery firing. One of the first significant developments that took place was the creation and refinement of the ‘clock code’ system. Using this system, a pilot of the Royal Flying Corps, the forerunner to the Royal Air Force (RAF), was able to correct the fall of shot of the artillery by passing to the artillery battery commander details of how far from the target the guns were. The pilot would correct the shooting of the artillery by pointing out how far away and in what direction the shells of the guns had landed. The distance would be passed on using numbers and the direction using the picture of a clock face. The target was placed in the middle of the clock face and shells that fell beyond the target and on a straight line to the target would be corrected with a call of twelve, if it fell short on the same line the call would be six, at ninety degrees left of the target nine and ninety degrees right three. Any other direction would be corrected by using the hour on the clock with which it corresponded. This system would prove to function perfectly well throughout the whole of the First World War and was the system with which the RAF went to war in 1939.
The system of correcting artillery fire remained unchanged until 1938. The Air Council were against making alterations to the clock code system as they felt that it was adequate to meet the needs that the army would face in future conflicts. They felt that light aircraft could not be kept in action close to artillery units, as had been the case in the First World War. The Air Council were also fearful of introducing a new, untried, and unfamiliar system with the growing tensions in Europe at this time. The War Office was unimpressed with the Air Councils attitude and pushed for more to be done. The Air Ministry agreed to trials between the Air Officer Commanding No. 22 (Army Co-operation) Group and the Commandant of the School of Artillery in December 1938. The results of these trials and further trials conducted to test aircraft as well as procedure. The results were that light aircraft over the battlefield could observe fire with the ‘clock code’ system. Spitfires conducted mock attacks on the aircraft and the Taylorcraft light aircraft observing the artillery fire had a good chance of dodging the fire of a modern fighter. There was, however, no training for pilots in registering targets for the artillery. If an artillery officer required an appraisal of a prospective target, the request would have to be sent along the command chain via an air liaison officer. When the artillery battery received the information, it was usually out of date. There was also pressure from within the War Office to establish a Flying Observation Post (Flying OP) and to begin plans to train Gunner Officers to fly. A Flying OP was to work in conjunction with Ground Observation Post (Ground OP) in establishing targets to be engaged and operating deep behind their lines to be afforded the protection of friendly anti-aircraft guns.
The first of these Flying OPs was established in February 1940. This force was established to:
[d]etermine in the light of practical experience obtained under war conditions the possibilities and limitations of the Flying OP, the most suitable type of aircraft and the most suitable organization [sic].
The tests were to be conducted in three parts. The first was an initial training period. The second a practical training with the French, and a final test in the French Army area in conditions of actual warfare including shoots against German targets it was at this time that the term Air Observation Post (Air OP) was adopted. The flight was sent to France on 19 April 1940. The first of the three tests were conducted after the flight had moved to the continent. The final of the three tests was due to be carried out in early May, and the forces were established ready to conduct the tests on 9 May 1940. The following day the Germans began to implement Fall Gelb (Case Yellow): the invasion of France and the Low Countries. The artillery designated for the tests were forced to move back to their formations leaving the Air OP Flight (D Flight) waiting for the campaign to stabilise when it was clear that this would not happen D Flight was recalled to England.
One of the first official moves at changing artillery co-operation policy was a letter regarding the subject sent from the Director of Military Co-operation Air Commodore Victor Goddard to Barratt at Army Co-operation Command. In this letter, Goddard states that the Air Staff were against the formation of:
[s]pecial air units for artillery observation or reconnaissance, unless it can be clearly shown that there is an urgent requirement for such units which cannot be met by Army Co-operations squadrons.
The School of Artillery recommended that a certain number of aircraft should specialise in artillery work and should be trained by the School of Artillery so that they had the same tactical knowledge and the same the understanding of gunnery as an artillery officer. This was just one aspect of an idea by the School of Artillery to allow aircraft to have tactical control over the fire of artillery batteries. To facilitate this, the school further recommended that a multi-seater aircraft should be employed in this work to allow an artillery officer to conduct the shoot according to artillery methods without the need for the artillery officer learning to fly. Artillery officers were also to be seconded to army co-operation squadrons specifically for artillery work. The co-operation between the School of Artillery and Army Co-operation Command is evident and is surprising given the general relations that existed between the army and RAF in the wake of the Battle of France and the fall out that it had caused between the two services.
Barratt, in a letter to the Under-Secretary of State for Air, wrote that:
I consider that in order to get a true and undistorted picture of this problem, it is first desirable to set out the problem as the Army [sic] sees it, and to show in this picture what they conceive to be their requirements.
Again the desire to see the problem from a view that would almost certainly be contradictory to the RAF shows that Barratt and his command were willing to adopt a different approach and attitude in co-operating with at least one part of the army. Barratt also voiced his concerns regarding the ability of the Air OP to operate in the face of enemy action. It was felt that ‘the Air OP must be entirely vulnerable to any enemy fighters which cares to shoot it down’. Barratt’s concern over the safety of his pilots who may be conducting shoots using the Air OP system was to be a recurring issue in the development of artillery reconnaissance.
Barratt’s response to the trials was one of scepticism, and he considered ‘that body of experience gained in the late war and since has all pointed to the advantages of the ‘Clock Code’ system’. Barratt’s belief in the ‘clock code’ system stemmed more from the fear of false conclusions being drawn from brief experiments than from any sense of conservatism about changing the system used for artillery reconnaissance. This became a realisation when Barratt was forced to explain to the Under Secretary of State for Air about the lack of efficiency regarding artillery co-operation in Army Co-operation Squadrons. Barratt wrote that:
I feel that much of the falling off in efficiency in this part of the Army Co-operation Squadron task has been due to the propagation of rumour as to other and better methods than those shown in AP 1176.
Further trials were conducted using the artillery method during April 1941, and the conclusions reached were similar to those seen previously. These were that the artillery methods of ranging by corrections to line and range are simpler, quicker, and more efficient than any method based on the ‘clock code’.
The failures of the ‘clock code’ system in France combined with further problems faced in the fighting in Libya led to a loss of confidence in the system in the army. Barratt responded that the ‘clock code’ system was not at fault in these operations but that the aircraft employed in it were operating in the face of intense enemy opposition. He was concerned that the trials had been too few and were skewed in favour of a positive result by the School of Artillery. While these concerns may be interpreted as merely blocking a new development that had been shown to work to preserve the autonomy of the RAF while conducting army co-operation work. The evidence of co-operation between Army Co-operation Command and the School of Artillery, shown above, leads more to the conclusion that Barratt felt that the procedure could not be successfully carried out, and wished to see more trials conducted before it would receive his approval.
The procedure for artillery reconnaissance first developed during the First World War was only suitable for the conditions of that war. The lack of fluidity and almost stable front lines allowed a system to develop, quickly, this system, however, was only suited to those conditions. This was very quickly discovered during the first major test of this procedure against the quicker and more mobile warfare of the German Wehrmacht in 1940. The attitudes of both the British Army and the RAF to co-operation during the inter-war period, in Britain at least, did little to improve the situation before the British Expeditionary Force was stationed in France. This left those charged with the responsibility of modifying the existing procedure with only the experience of the First World War to guide them and on which to base their expectations. Much co-operation between the School of Artillery and Nos. 70 and 71 Groups of Army Co-operation Command occurred, despite the general feeling of animosity still felt by both services in Britain. This co-operation was the most that had been seen between the army and RAF since the formation of the RAF as an independent force in 1918. Barratt’s move to block the adoption of the new procedure that was being trialled during 1941 can be interpreted in several ways. His reasoning for doing so, however, appears to be that of confirming the results already achieved through more rigorous and testing trials to confirm the results. Through further testing at a higher level the procedure, as well as those responsible for carrying it out, would be exposed to more stress and so a greater degree of authenticity could be achieved. Trials of this nature would also confirm if the procedure could be implemented with ease by the majority of pilots whose responsibility would be increased from observing the fall of shot to conducting shoots, potentially in the face of enemy opposition. Barratt’s major concern with the new system appears to be its increased complexity, and he was rightly concerned after his experiences in France that pilots would be unable to conduct the shoot if they had to keep a lookout for enemy fighter activity continually.
