INTRODUCTION

t should be clear to you that the inter-war years were not peaceful. After the conclusion of the Paris Peace Treaties, a number of countries remained in a state of at least partial mobilisation. There were a number of flashpoints around the world, some resulting from the treaties signed at Paris. The complexity of the state of affairs, internationally, makes it difficult for modern historians to say with any certainty when exactly the war began. Did the war start with the familiar image of German soldiers lifting the frontier barrier on the Polish border in 1939? Or did it actually commence with the advance into the Rhineland in 1936, or the annexation of the Sudetenland, or Austria, or Czechoslovakia? For the Jews, as a people, one might decide upon 1933 (the year Hitler came to power) or 1935 (the year when the race laws were promulgated) or the Kristalnacht in 1938.

Ian Buruma surmises that many Germans attempt to side step the issue by referring to the Hitlerzeit (Hitler era) instead of "the war." "The war" as a concept is generally reserved for the images of soldiers freezing on the Eastern Front and the strategic bombardment of German cities.

In the Far East, ‘different’ World War was fought. "In Japan, the establishment of a puppet state in Manchuria in 1931 was a hostile harbinger of much to come. But the invasion of China proper began in 1937 with a shoot-out near Beijing, and the Pacific War started with the attack on Pearl Harbor in four years later. Incidentally, only Japanese of a liberal disposition call World War II the Pacific War. People who stick to the idea that Japan was fighting a war to liberate Asia from Bolshevism and white colonialism call it the Great East Asian War (Daitowa Senso), as in the Great East Asian Co-Prosperity Sphere. People of this opinion separate the world war of 1941-1945 from the war in China, which they still insist on calling the China Incident. Liberals and leftists, on the other hand, tend to splice these wars together and call then the Fifteen-Year War (1931-45). Hayashi Fusao, the author of In Affirmation of the Great East Asian War and definitely not a libreral, argued that the struggle against Western imperialism actually began in 1853, with the arrival in Japan of Commodore Perry’s ships, and spoke of the Hundred-Year War."

The inter-war period also saw a number of technological developments that obviously impacted upon the development in weapon systems and the evolution of military theory. The most important new weapon systems were the tank and the aircraft; both of which appeared as the First World War was ending.

In 1943, Edward Warner published a criticism of the early air-warfare theoreticians: Douhet, Mitchell, and Seversky. Warner opined that, essentially, the early debates did not revolve around the employment of air forces. To his mind they dealt (instead) with the acceptance or rejection of the ‘fundamental doctrine’ that aircraft could destroy any land target and - as a result of speed and height - were also immune from reprisal from land forces. Thus aircraft were the dominant instrument of war.

According to Warner, the theory of Guilio Douhet (1869-1930) could be translated into five key points:

While Douhet was quite justified in his prediction regarding gas bombs, he may be criticised on the following grounds: William Mitchell (1879-1936) stressed the enemy industrial base and economic structure as the preferred target. He also predicted that air power would dominate land warfare but saw a role for all types of aircraft (bombers as well as fighters). Thus strategic bombardment was not all-important. Like Douhet, Mitchell thought it best to centralise co-ordination of air power under the control of an autonomous air force command.

Unlike Douhet and Mitchell, Alexander de Seversky (1894-1974) was not an air theorist per se. Seversky’s popular thesis entitled Victory Through Air Power (1942) together with a Walt Disney film released in July 1943, brought him fame greater than his contribution to the theory of air power. Favouring air power over all other means of warfare, Seversky, in effect, said nothing new.

Sir Hugh (later Lord) Trenchard (1873-1956) was, as British Air Chief of Staff from 1919 to 1929, became creator of the Royal Air Force. Failing to gain entry into the Royal Navy, he was commissioned into the army in 1893 and served in India and South Africa (during the Anglo-Boer War). Having attained a pilot’s license in 1912, he became RFC commander in France, where he organised fighter battles against the Germans, the latter equipped with a superior Fokker monoplane. In the same theatre, Trenchard developed the use of bombers aimed at military targets in Germany and France.

Trenchard envisioned a two-fold purpose for strategic bombers. These were to destroy the enemy’s:

According Trenchard, air warfare held a number of advantages: Air warfare to his mind was also defensive by nature. He thought that the threat to cities would act as deterrent. Instead the very failure of air power as a deterrent lead to calamity total war throughout much of Europe and parts of Asia.

The mechanised warfare theorists, Fuller and Liddell Hart, recognised the potential co-operation between land and air forces in armoured warfare. Liddell Hart predicted the use of dive-bombers as a substitute for artillery.

During the inter-war period (1919-1939), a number of developments took place in various countries in terms of the deployment of air power. Take a look at these developments and their shortcomings, with regard to the following states:

It should be clear that the theories were not derived from commonly accepted principles of air power. In a nutshell, there was no Jomini (land warfare) or Mahan (sea warfare). Air power was simply applied according to national objectives. And in most countries there was an effort to create independent air forces.

TACTICAL & STRATEGIC USE OF AIRCRAFT

McInnes and Sheffield, Warfare in the Twentieth Century, pp 43-48.

Jones, The Art of War in the Western World, p 501.

Aircraft, as a new weapon system, were applied and tested by a number of Western states during the inter-war period. Aircraft proved the supreme weapon system in dealing with massed "feudal" armies. Our first case study is close to home. What become known as the Bondelswart Uprising occurred a brief three years after the end of the First World War; and immediately showed the value of a tactical air force to a still sceptical public.

The Bondelswart tribe, located in modern Namibia, protested against a South African government decision not to concede certain land claims. A force was raised in May 1922, when the captain of the tribe refused to deliver a number of his followers who were allegedly guilty of misdemeanour and theft. The force initially comprised two field guns and one hundred mounted troops. This force surrounded and bombarded Haib, the Bondelswart stronghold, on 29 May. On 30 May the settlement surrendered after their leader, Abraham Morris, together with approximately fifty followers had escaped through the cordon. Morris hoped to join Nicolaas Christiaan and his men, and make a stand in their ancient stronghold - the Fish River Canyon. In an attempt to prevent the insurrection from spreading to the Richtersveld, an airstrip was prepared near Steinkopf and two aircraft dispatched to the area from Pretoria. On 2 June, one of these aircraft spotted smoke in a saucer in the mountains; and the Bondelswart were bombed and machine-gunned from the air. Some 20 were killed and more wounded: the survivors learned to hide by day and move at night. They ate their last donkey on 4 June and in a skirmish with ground troops on the same day, Morris was killed. What remained of his followers surrendered on 7 June. Over the following weeks, the two aircraft made intimidation flights over all the reserves around Keetmanshoop.

The Italo-Ethiopian War (1935-36) presents us with a second case study on how a developed country could exploit its technology and, with relative ease, conquer a foe with less-developed weapon systems at its disposal. Again aircraft played the premier role and, without anti-aircraft guns, the Ethiopians proved defenceless. One of South Africa’s official historians, James Ambrose Brown, wrote as follows:

"Abyssinia, primitive and inaccessible in 1935, had been largely conquered from the air. In the campaign of Marshal Badoglio, Italian air-power, then at its peak, had been used with ruthless ability against the massed armies of chieftains and feudal lords. It had attacked the miles-long processions of peasant foot soldiers, mule trains and camp followers, pursued armies broken in battle along the only escape routes, leaving a debris of corpses at every river crossing and mountain pass. It had harried the Emperor Haile Selassie from cave to cave and laid waste the land with incendiary bomb and mustard gas. The Emperor himself manned an Oerlikon and marvelled at the Italian airmen’s skill and daring in low-level attack. The Italian Air Force was estimated to be over 300 aircraft on the northern front and 100 more were active in Somaliland. Against these the Ethiopians had eleven communications aircraft, eight serviceable, none armed.

"The build-up of Italian air-power had begun when Mussolini decided that 1935 was to be the year of destiny in East Africa. Air bases and assembly workshops were erected in the colonies of Eritrea and Somaliland. 

"Soon Abyssinia was surrounded by a chain of airfields from which bombers could operate. Reconnaissance aircraft penetrated the territory to be invaded and the first accurate maps were produced. Vast supplies of munitions and fuel were moved forward on new highways. Asmara, in 1935 a small town of 3,000 people, grew to a population of 17,500 in twelve months. Great concrete runways and hangars emerged from the empty landscape at Gura and Asmara; at Mai Edaga the Caproni ‘Colonial’ bomber and C.R.42 fighter were assembled at a rate of six a day.

"Against the Regia Aeronautica the Abyssinians were powerless; barefoot levies in white cotton shammas were unprepared for the terror from the sky - though they did manage to shoot down eight aircraft with a few modern weapons obtained late in the campaign. Against medieval armies Italian aircraft were used in the role of cavalry. On a single pursuit action they made no less than 546 sorties; in an operation at Amba Alagi in which 250 aircraft were used, 40 tons of bombs were dropped in five hours. These were the most intensive aerial bombardments the world had yet seen.

"The conquest complete, the Emperor fled. The Italians moved in to consolidate their victory. A great new airfield was constructed at Addis Ababa and others were built across the far-flung table-lands in every province; and the work of subjugation went on."

J.A. Brown, A Gathering of Eagles, p 30.
 
Finally, during the Spanish Civil War (1936-37), government aircraft provided valuable assistance in repelling the advance of two largely motorised Italian divisions. Confined to the road, these columns provided wonderful targets to attacking aircraft. What "lessons" were learned and/or incorrectly deduced? [Read Jones, p 501.]
 

THE NAVIES RESPONSE TO THE NEW WEAPONS


Jones, The Art of War in the Western World, pp 502-504

After the First World War naval architects realised that ships’ armour was totally inadequate against long-rage gunfire. Their remedy to improve defence comprised the:

There were also major developments for the attack: Finally, critically discuss the difficulties experience in finding the best doctrine. Refer to the relevant pages in Jones.
 

THE "LESSONS" OF THE FIRST WORLD WAR & THE DIVERGENT DOCTRINES OF THE VARIOUS ARMED FORCES

Strachan, European Armies and the Conduct of War, pp 150-164.
Jones, The Art of War in the Western World, pp 504-507.
Lyons, World War II; A Short History, pp 67-71.

The First World War was of an unprecedented nature. Although the dominance of the trench was taken as proof that the defence was the superior means, many soldiers were keen to restore power to the attack. Analyse the so-called "lessons" of the First World War as identified by the various armed forces. How did these "lessons" influence the development of strategies and tactics in the inter-war period? Remember the dictum that most countries initially prosecute a war based upon their experiences of the previous war.
