The General Electric J31 was the first jet engine to be mass-produced in the United States .
162-587: After a visit to England mid-1941, General Henry H. Arnold was so impressed by flight demonstrations of the Gloster E.28/39 jet aircraft he had witnessed that he arranged for the Power Jets W.1 X turbojet engine to be shipped by air to the U.S, along with drawings for the more powerful W.2B/23 engine, so that the US could develop its own jet engine. General Electric 's extensive experience in turbocharger production made them
324-630: A blue-water navy was vital for global power projection; Tirpitz had his books translated into German, while Wilhelm made them required reading for his advisors and senior military personnel. However, it was also an emotional decision, driven by Wilhelm's simultaneous admiration for the Royal Navy and desire to surpass it. Bismarck thought that the British would not interfere in Europe, as long as its maritime supremacy remained secure, but his dismissal in 1890 led to
486-618: A fear of flying that resulted from his experiences with early flight, supervised the expansion of the Air Service during World War I , and became a protégé of then Brigadier General (later Colonel) Billy Mitchell . Arnold rose to command the Army Air Forces immediately prior to the American entry into World War II and directed its hundred-fold expansion from an organization of little more than 20,000 men and 800 first-line combat aircraft into

An hour later, as Ferdinand was returning from visiting the injured officers in hospital, his car took a wrong turn into a street where Gavrilo Princip was standing. He fired two pistol shots, fatally wounding Ferdinand and his wife Sophie . According to historian Zbyněk Zeman , in Vienna "the event almost failed to make any impression whatsoever. On 28 and 29 June,
810-536: A guerrilla warfare campaign and only surrendered two weeks after the armistice took effect in Europe. Before the war, Germany had attempted to use Indian nationalism and pan-Islamism to its advantage, a policy continued post-1914 by instigating uprisings in India , while the Niedermayer–Hentig Expedition urged Afghanistan to join the war on the side of Central Powers. However, contrary to British fears of
972-656: A proprietary metal developed for their turbochargers, Hastelloy B . Using their turbocharger expertise, General Electric were able to, in a short space of time, develop a 1,400 lbf (6.2 kN )-thrust version, known as the I-14. Later they increased the thrust to 1,600 lbf (7.1 kN ). This version was referred to internally as the I-16 However, the United States Army Air Forces later decided to standardize all their jet engine naming, at which point
1134-425: A "Juliette" (one month late), having just turned 17. His cadet career was spent as a "clean sleeve" (cadet private). At the academy he helped found the "Black Hand", a group of cadet pranksters, and led it during his first class year . He played second-team running back for the varsity football team, was a shot putter on the track and field team, and excelled at polo . Arnold's academic standing varied between
1296-408: A change in policy and an Anglo-German naval arms race began. Despite the vast sums spent by Tirpitz, the launch of HMS Dreadnought in 1906 gave the British a technological advantage. Ultimately, the race diverted huge resources into creating a German navy large enough to antagonise Britain, but not defeat it; in 1911, Chancellor Theobald von Bethmann Hollweg acknowledged defeat, leading to
1458-563: A day in a Curtiss JN trainer , a much safer aircraft with a simpler flight control system than the Speed Scout of just four years' before. On November 26, he flew solo, and on December 16 qualified again for his JMA. Before he could be reassigned to flying duties, however, he was involved as a witness in a controversial service dispute in January 1917. Over the objections of Captain Herbert A. Dargue ,
1620-592: A direct threat. The 1908–1909 Bosnian Crisis began when Austria annexed the former Ottoman territory of Bosnia and Herzegovina , which it had occupied since 1878. Timed to coincide with the Bulgarian Declaration of Independence from the Ottoman Empire, this unilateral action was denounced by the European powers, but accepted as there was no consensus on how to resolve the situation. Some historians see this as
1782-417: A farm field after getting lost. In September Arnold became the first U.S. pilot to carry mail, flying a bundle of letters five miles (8 km) on Long Island , New York, and he is credited as the first pilot to fly over the U.S. Capitol and the first to carry a United States Congressman as a passenger. The following month, Arnold moonlighted as a pilot in the filming of two silent movies, doubling for
SECTION 10
#17328526318531944-404: A fatal crash. He immediately grounded himself and applied for a leave of absence. Flying was considered so dangerous that no stigma was attached for refusing to fly, and his request was granted. During his leave of absence he renewed an acquaintance with Eleanor "Bee" Pool, the daughter of a banker, and one of his father's patients. On December 1, Arnold took a staff assignment as assistant to
2106-498: A fitness report that stated "in an emergency he is liable to lose his head", Arnold made a commitment to remain in the service, turning down an offer of the presidency of the soon-to-be operating Pan American Airways , which he had helped bring into being. Arnold made the best of his exile and in May 1927, his participation in war games at Fort Sam Houston , Texas , impressed Major General James E. Fechet , successor to Patrick as Chief of
2268-467: A gap between the German armies as they closed on Paris. The French army, reinforced by the British expeditionary corps, seized this opportunity to counter-attack and pushed the German army 40 to 80 km back. Both armies were then so exhausted that no decisive move could be implemented, so they settled in trenches, with the vain hope of breaking through as soon as they could build local superiority. In 1911,
2430-489: A general court-martial, but when Arnold chose the latter, Patrick decided to avoid another public fiasco and instead transferred him to Ft. Riley, far from the aviation mainstream, where he took command of the 16th Observation Squadron on March 22, 1926. Patrick's press release on the investigation stated that Arnold was also reprimanded for violating Army General Order No. 20 by attempting "to influence legislation in an improper manner." Despite this setback, which included
2592-540: A possibility. This was accentuated by British and Russian support for France against Germany during the 1911 Agadir Crisis . German economic and industrial strength continued to expand rapidly post-1871. Backed by Wilhelm II, Admiral Alfred von Tirpitz sought to use this growth to build an Imperial German Navy , that could compete with the British Royal Navy . This policy was based on the work of US naval author Alfred Thayer Mahan , who argued that possession of
2754-649: A promotion to major on June 27, as assistant executive officer of the Aeronautical Division, and then as executive officer after it became the Air Division on October 1. On August 5, 1917, he was promoted again, becoming the youngest full colonel in the Army. Arnold gained experience in aircraft production and procurement, the construction of air schools and airfields, and the recruitment and training of large numbers of personnel; and learned political in-fighting in
2916-799: A revolt in India, the outbreak of the war saw a reduction in nationalist activity. Leaders from the Indian National Congress and other groups believed support for the British war effort would hasten Indian Home Rule , a promise allegedly made explicit in 1917 by Edwin Montagu , the Secretary of State for India . In 1914, the British Indian Army was larger than the British Army itself, and between 1914 and 1918 an estimated 1.3 million Indian soldiers and labourers served in Europe, Africa, and
3078-504: A significant escalation, ending any chance of Austria cooperating with Russia in the Balkans, while also damaging diplomatic relations between Serbia and Italy. Tensions increased after the 1911–1912 Italo-Turkish War demonstrated Ottoman weakness and led to the formation of the Balkan League , an alliance of Serbia, Bulgaria, Montenegro , and Greece . The League quickly overran most of
3240-557: A silent film stunt pilot in October 1911, or to his wife, who began using the nickname in her correspondence in 1931 following the death of Arnold's mother. His family called him Harley during his youth, and his mother and wife called him "Sunny". His West Point classmates called Arnold "Pewt" or "Benny" and his immediate subordinates and headquarters staff referred to him as "The Chief". Born June 25, 1886, in Gladwyne, Pennsylvania , Arnold
3402-725: A site that later became Edwards Air Force Base . In 1934, Chief of Air Corps Benjamin D. Foulois named Arnold to command one of the three military zones of the controversial Army Air Corps Mail Operation , with a temporary headquarters in Salt Lake City, Utah . Arnold's pilots performed well and his own reputation was untouched by the fiasco. Later that same year he won his second Mackay Trophy, when he led ten Martin B-10 B bombers on an 8,290-mile (13,340 km) flight from Bolling Field to Fairbanks, Alaska , and back. Overly credited with its success, he nonetheless lobbied for recognition of

It also planned for an expansion of the AAF to 60,000 aircraft and 2.1 million men. AWPD/1 called for 24 groups (approximately 750 airplanes) of very long range B-29 bombers to be based in Northern Ireland and Egypt for use against Nazi Germany, and for production of sufficient Consolidated B-36s for intercontinental bombing missions of Germany. Soon after U.S. entry in
3726-650: A supporter of Arnold, submitted his name with two others for promotion to the permanent rank of major general. Roosevelt refused to send the list to the Senate for confirmation because of Arnold's nomination, and his forced retirement from the service seemed imminent to both Stimson and Marshall. Stimson and Harry Hopkins arranged for Arnold, accompanied by Major Elwood "Pete" Quesada , to travel to England for three weeks in April to evaluate British aircraft production needs and to provide an up-to-date strategic analysis. One outcome of
3888-471: A war on two fronts; the Schlieffen Plan envisaged using 80% of the army to defeat France, then switching to Russia. Since this required them to move quickly, mobilization orders were issued that afternoon. Once the German ultimatum to Russia expired on the morning of 1 August, the two countries were at war. At a meeting on 29 July, the British cabinet had narrowly decided its obligations to Belgium under
4050-402: A weak Ottoman government, rather than an ambitious Slav power like Bulgaria . Russia had ambitions in northeastern Anatolia while its clients had overlapping claims in the Balkans. These competing interests divided Russian policy-makers and added to regional instability. Austrian statesmen viewed the Balkans as essential for the continued existence of their Empire and saw Serbian expansion as
4212-451: A whole, the Somme offensive led to an estimated 420,000 British casualties, along with 200,000 French and 500,000 Germans. The diseases that emerged in the trenches were a major killer on both sides. The living conditions led to disease and infection, such as trench foot , lice , typhus , trench fever , and the ' Spanish flu '. At the start of the war, German cruisers were scattered across
4374-449: A wing tip in the water turning into the wind and crashed into the bay off Plymouth . Arnold suffered a lacerated chin during the mishap but the aircraft was salvaged and repaired. Another crash at College Park on September 18 killed 2nd Lieutenant Lewis Rockwell, an academy classmate of Arnold's. In October, Arnold and Milling were ordered to enter the competition for the first MacKay Trophy for "the most outstanding military flight of
4536-850: A year later. He also was recognized by a general order in 1913 as one of the first 24 rated military aviators , authorized to wear the newly designed Military Aviator badge. After several more weeks of solo flying in Dayton to gain experience, Arnold and Milling were sent on June 14 to the Aeronautical Division, Signal Corps station established at College Park, Maryland , to be the Army's first flight instructors. There Arnold set an altitude record of 3,260 feet (990 m) on July 7 and thrice broke it (August 18, 1911, to 4,167 feet (1,270 m); January 25, 1912, to 4,764 feet (1,452 m); and June 1, 1912, 6,540 feet (1,990 m)). In August 1911, he experienced his first crash, trying to take off from
4698-503: Is known, however, that from 1908 to 1913, military spending by the six major European powers increased by over 50% in real terms. The years before 1914 were marked by a series of crises in the Balkans, as other powers sought to benefit from the Ottoman decline. While Pan-Slavic and Orthodox Russia considered itself the protector of Serbia and other Slav states, they preferred the strategically vital Bosporus straits to be controlled by
4860-558: The Schutzkorps was established, and carried out the persecution of Serbs. The assassination initiated the July Crisis, a month of diplomatic manoeuvring between Austria-Hungary, Germany, Russia, France and Britain. Believing that Serbian intelligence helped organise Franz Ferdinand's murder, Austrian officials wanted to use the opportunity to end their interference in Bosnia and saw war as
5022-626: The World War . In August 1914, the magazine The Independent wrote "This is the Great War. It names itself". In October 1914, the Canadian magazine Maclean's similarly wrote, "Some wars name themselves. This is the Great War." Contemporary Europeans also referred to it as " the war to end war " and it was also described as "the war to end all wars" due to their perception of its unparalleled scale, devastation, and loss of life. The first recorded use of

5184-665: The Australian Naval and Military Expeditionary Force landed on the island of New Britain , then part of German New Guinea . On 28 October, the German cruiser SMS Emden sank the Russian cruiser Zhemchug in the Battle of Penang . Japan declared war on Germany before seizing territories in the Pacific, which later became the South Seas Mandate , as well as German Treaty ports on
5346-714: The B-17 and the concept of Jet-assisted takeoff . To encourage the use of civilian expertise, the California Institute of Technology became a beneficiary of Air Corps funding and Theodore von Kármán of its Guggenheim Aeronautical Laboratory developed a good working relationship with Arnold that led to the creation of the Scientific Advisory Group in 1944. Arnold characterized his wartime philosophy of research and development as: "Sacrifice some quality to get sufficient quantity to supply all fighting units. Never follow
5508-621: The Eighth Air Force , and he named Spaatz to command it and Eaker to head its Bomber Command. Other Arnold protégés eventually filled key positions in the strategic bombing forces, including Haywood S. Hansell , Laurence S. Kuter , and James H. Doolittle . Despite protecting his strategic bombing force from demands of other services and allies, Arnold was forced to divert resources from the Eighth to support operations in North Africa , crippling
5670-565: The Fairfield Air Service Depot , Ohio. In 1930 he also became Chief of the Field Service Section, Air Corps Materiel Division, and was promoted to lieutenant colonel on February 1, 1931. Arnold's parents were made destitute by the bank collapses in 1929 , and on January 18, 1931, his mother died of a sudden heart attack. Arnold struggled emotionally with being absent from his parents' 50th wedding anniversary celebration
5832-529: The Far East to destroy Japanese military power and combustible cities. Arnold was responsible for approving the Army Air Forces Women's Flying Training Detachment (WFTD). It was approved by September 14, 1942, and directed by aviator Jacqueline Cochran . Immediately after the attack on Pearl Harbor Arnold began to carry out AWPD/1 . The primary strategic bombing force against Nazi Germany would be
5994-808: The First World War (28 July 1914 – 11 November 1918), also known as the Great War , was a global conflict between two coalitions: the Allies (or Entente) and the Central Powers . Fighting took place mainly in Europe and the Middle East , as well as in parts of Africa and the Asia-Pacific , and in Europe was characterised by trench warfare ; the widespread use of artillery , machine guns, and chemical weapons (gas); and
6156-590: The House Military Affairs Committee against HR5304, a bill to remove aviation from the Signal Corps and make it a semi-autonomous "Air Corps." Arnold, like fellow flyer Captain Benjamin Foulois , argued that the action was premature, and like his Signal Corps boss, Major Edgar Russel (a non-flyer), that the Signal Corps was doing all that could be done to develop military use of the airplane. He
6318-706: The Rüstungswende or 'armaments turning point', when he switched expenditure from the navy to the army. This decision was not driven by a reduction in political tensions but by German concern over Russia's quick recovery from its defeat in the Russo-Japanese War and subsequent 1905 Russian Revolution . Economic reforms led to a significant post-1908 expansion of railways and transportation infrastructure, particularly in its western border regions. Since Germany and Austria-Hungary relied on faster mobilisation to compensate for their numerical inferiority compared to Russia,
6480-600: The Twentieth Air Force . This unique command arrangement may also have contributed to his health problems (see below), but after the negative experiences of building an effective bombing force against Germany, and realizing the consequences of failure against Japan, Arnold concluded that, absent any unity of command in the Pacific theaters, administrative decisions regarding B-29 bomber operations could best be handled personally. However, theater commanders Douglas MacArthur , Chester Nimitz , and Joseph Stilwell all coveted
6642-538: The U.S. Army Air Corps . He also received outstanding fitness reports from his commanders at Ft. Riley, Brigadier General Ewing E. Booth (who had been a member of the Mitchell court) and his successor, Brig. Gen. Charles J. Symmonds . Repairs to Arnold's service reputation may also have been aided by a professional article he wrote for the Cavalry Journal in January 1928, showing the influence of his association with

6804-506: The United States Army Ordnance Department because it offered an immediate promotion to first lieutenant . While awaiting the results of the required competitive examination, he learned that his interest in aeronautics had not been forgotten. Arnold immediately sent a letter requesting a transfer to the Signal Corps and on April 21, 1911, received Special Order 95, detailing him and 2nd Lt. Thomas DeWitt Milling of
6966-784: The United States entered the war on the Allied side following Germany's resumption of unrestricted submarine warfare against Atlantic shipping. Later that year, the Bolsheviks seized power in the Russian October Revolution , and Soviet Russia signed an armistice with the Central Powers in December, followed by a separate peace in March 1918. That month, Germany launched an offensive in

Cowan contacted Arnold, who cabled his interest in also transferring to the Signal Corps but heard nothing in reply for two years. In June 1909, the 29th Infantry relocated to Fort Jay , New York , and en route to his new duty station by way of Paris , Arnold saw his first airplane in flight, piloted by Louis Blériot . In 1911, Arnold applied for transfer to
7290-480: The hydrophone and depth charges were introduced, destroyers could potentially successfully attack a submerged submarine. Convoys slowed the flow of supplies since ships had to wait as convoys were assembled; the solution was an extensive program of building new freighters. Troopships were too fast for the submarines and did not travel the North Atlantic in convoys. The U-boats sunk more than 5,000 Allied ships, at
7452-789: The tank . After the First Battle of the Marne in September 1914, Allied and German forces unsuccessfully tried to outflank each other, a series of manoeuvres later known as the " Race to the Sea ". By the end of 1914, the opposing forces confronted each other along an uninterrupted line of entrenched positions from the Channel to the Swiss border. Since the Germans were normally able to choose where to stand, they generally held

While individually instructed, they were part of the school's May 1911 class that included three civilians and Lieutenant John Rodgers of the United States Navy . Beginning instruction on May 3 with Arthur L. Welsh , Arnold made his first solo flight May 13 after three hours and forty-eight minutes of flight in 28 lessons. On May 14, he and Milling completed their instruction. Arnold received Fédération Aéronautique Internationale (FAI) pilot certificate number 29 on July 6, 1911, and Military Aviator Certificate Number 2
7776-588: The 1839 Treaty of London did not require it to oppose a German invasion with military force; however, Prime Minister Asquith and his senior Cabinet ministers were already committed to supporting France, the Royal Navy had been mobilised, and public opinion was strongly in favour of intervention. On 31 July, Britain sent notes to Germany and France, asking them to respect Belgian neutrality; France pledged to do so, but Germany did not reply. Aware of German plans to attack through Belgium, French Commander-in-Chief Joseph Joffre asked his government for permission to cross
7938-431: The 1879 Dual Alliance , which became the Triple Alliance when Italy joined in 1882. For Bismarck, the purpose of these agreements was to isolate France by ensuring the three Empires resolve any disputes between themselves. In 1887, Bismarck set up the Reinsurance Treaty , a secret agreement between Germany and Russia to remain neutral if either were attacked by France or Austria-Hungary. For Bismarck, peace with Russia
8100-441: The 1913 Treaty of London , which had created an independent Albania while enlarging the territories of Bulgaria, Serbia, Montenegro and Greece. However, disputes between the victors sparked the 33-day Second Balkan War , when Bulgaria attacked Serbia and Greece on 16 June 1913; it was defeated, losing most of Macedonia to Serbia and Greece, and Southern Dobruja to Romania. The result was that even countries which benefited from

Wolfe in India in July 1944, and later Hansell on Guam in January 1945. With the strategic bombing crisis resolved in Europe, Arnold placed full emphasis on completion of the development and deployment of the B-29 Very Long Range (VLR) bomber to attack Japan. As early as 1942, Arnold planned to make himself commanding general of

#17328526318538424-422: The Air Force into a service co-equal with the Army and Navy was postponed until after the war. In July Roosevelt asked for production requirements to defeat potential enemies, and Arnold endorsed a request by his new Air War Plans Division to submit an air war plan. The assessment, designated AWPD/1 , defined four tasks for the AAF: defense of the Western Hemisphere, an initial defensive strategy against Japan,
8586-400: The Allies would slow delivery to the Air Corps, particularly since control of the allotment of aircraft production had been given to the Procurement Division of the Treasury Department in December 1938, and by extension, to Treasury Secretary Henry Morgenthau Jr. , a White House favorite. Arnold experienced two years of difficulties with Morgenthau, who was prone to denigrate the leadership of
8748-449: The Army Ground Forces and Services of Supply. The Air Force Combat Command and the Office of the Chief of Air Corps were abolished, and Arnold became AAF Commanding General and an ex officio member of both the Joint Chiefs of Staff and the Combined Chiefs of Staff . In response to an August 1942 directive, Arnold had the AWPD revise its estimates. AWPD/42 resulted, calling for 75,000 aircraft and 2.7 million men, and increased
8910-466: The Assistant Chief of Air Corps vacancy. After Charles Lindbergh publicly lent his support in April 1939 for production of a very long range bomber in large numbers to counter Nazi production, development of which had been prohibited since June 1938 by the Secretary of War, Arnold appointed Kilner to head a board to make appropriate recommendations to end the R&D moratorium. Arnold encouraged research and development efforts, among his projects
9072-409: The Austrians and Serbs clashed at the battles of the Cer and Kolubara ; over the next two weeks, Austrian attacks were repulsed with heavy losses. As a result, Austria had to keep sizeable forces on the Serbian front, weakening their efforts against Russia. Serbia's victory against Austria-Hungary in the 1914 invasion has been called one of the major upset victories of the twentieth century. In 1915,
9234-593: The Austrians briefly occupied the Serbian capital, Belgrade . A Serbian counter-attack in the Battle of Kolubara succeeded in driving them from the country by the end of 1914. For the first 10 months of 1915, Austria-Hungary used most of its military reserves to fight Italy. German and Austro-Hungarian diplomats scored a coup by persuading Bulgaria to join the attack on Serbia. The Austro-Hungarian provinces of Slovenia , Croatia and Bosnia provided troops for Austria-Hungary. Montenegro allied itself with Serbia. Bulgaria declared war on Serbia on 14 October 1915 and joined in

Lahm , the school secretary (adjutant), authorized on January 6 an excursion flight for a non-aviator that took place on January 10, again over Dargue's protests, resulting in the loss of the airplane in Mexico and the disappearance of the crew for nine days. After testifying to army investigators on January 27, confirming that Lahm had authorized

King , that the Twentieth was unique in that its operations cut across the jurisdiction of all three theaters, and thus should report directly to the Joint Chiefs with Arnold acting as their executive agent. In February 1944 President Roosevelt agreed and approved
9720-493: The Balkan Wars, such as Serbia and Greece, felt cheated of their "rightful gains", while for Austria it demonstrated the apparent indifference with which other powers viewed their concerns, including Germany. This complex mix of resentment, nationalism and insecurity helps explain why the pre-1914 Balkans became known as the " powder keg of Europe ". On 28 June 1914, Archduke Franz Ferdinand of Austria , heir presumptive to Emperor Franz Joseph I of Austria , visited Sarajevo ,
9882-416: The Cavalry School at Fort Riley. Arnold urged a strong combined arms team be developed between the Air Corps and the Cavalry; and by extension, all ground forces. This opportunity for development of the concept in both theory and practice was lost however, by the effects of cultural differences between the two service branches and the dominance of American isolationism. It did not develop until the United States

After Vienna refused to withdraw its cruiser SMS Kaiserin Elisabeth from Tsingtao, Japan declared war on Austria-Hungary, and the ship was sunk in November 1914. Within a few months, Allied forces had seized all German territories in the Pacific, leaving only isolated commerce raiders and a few holdouts in New Guinea. Some of the first clashes of

Eaker (now Eighth Air Force commander) found from experience that the pre-war doctrine of daylight precision bombing, developed at the Air Corps Tactical School as a foundation for separating the Air Force from the Army, was mistaken in its tenet that heavily armed bombers could reach any target without the support of long-range escort fighters. Early in 1943 he began requesting more fighters and jettisonable fuel tanks to increase their range, in addition to repeated requests to increase
10530-548: The German High Seas Fleet was confined to port. German U-boats attempted to cut the supply lines between North America and Britain. The nature of submarine warfare meant that attacks often came without warning, giving the crews of the merchant ships little hope of survival. The United States launched a protest, and Germany changed its rules of engagement. After the sinking of the passenger ship RMS Lusitania in 1915, Germany promised not to target passenger liners, while Britain armed its merchant ships, placing them beyond
10692-465: The German Army increased in size from 1908 to 1914, he changed the allocation of forces between the two wings to 70:30. He also considered Dutch neutrality essential for German trade and cancelled the incursion into the Netherlands, which meant any delays in Belgium threatened the viability of the plan. Historian Richard Holmes argues that these changes meant the right wing was not strong enough to achieve decisive success. The initial German advance in
10854-462: The German right wing would sweep through the Netherlands and Belgium , then swing south, encircling Paris and trapping the French army against the Swiss border. The plan's creator, Alfred von Schlieffen , head of the German General Staff from 1891 to 1906, estimated that this would take six weeks, after which the German army would transfer to the East and defeat the Russians. The plan was substantially modified by his successor, Helmuth von Moltke
11016-426: The Germans bled heavily as well, with anywhere from 700,000 to 975,000 casualties between the two combatants. Verdun became a symbol of French determination and self-sacrifice. The Battle of the Somme was an Anglo-French offensive from July to November 1916. The opening day on 1 July 1916 was the bloodiest single day in the history of the British Army , which suffered 57,500 casualties, including 19,200 dead. As

GE also used the basic design to produce the much larger I-40 with 4,000 lbf, but this design was passed on to Allison as the J33 . Another derivative of the J31, the General Electric I-20, given the military designation J39,

The suffering engendered by the war, as well as the failure of the British government to grant self-government to India afterward, bred disillusionment, resulting in the campaign for full independence led by Mahatma Gandhi . Pre-war military tactics that had emphasised open warfare and individual riflemen proved obsolete when confronted with conditions prevailing in 1914. Technological advances allowed

Foulois had retired under fire in the wake of the Air Mail scandal and allegations of corruption in Air Corps procurement, and the new chief, Major General Oscar Westover , had asked Craig for Arnold to fill the vacant assistant chief position. Over Arnold's protests, and despite a left-handed recommendation by Secretary of War George Dern , who recalled Arnold's close association with Billy Mitchell, Craig made him Assistant Chief of Air Corps, responsible for procurement and supply, to deal with
11664-859: The Ottoman Empire , which disturbed the long-standing balance of power in Europe, as well as economic competition between nations triggered by industrialisation and imperialism . Growing tensions between the great powers and in the Balkans reached a breaking point on 28 June 1914, when a Bosnian Serb named Gavrilo Princip assassinated Archduke Franz Ferdinand , heir to the Austro-Hungarian throne. Austria-Hungary held Serbia responsible, and declared war on 28 July. After Russia mobilised in Serbia's defence, Germany declared war on Russia and France , who had an alliance . The United Kingdom entered after Germany invaded Belgium , whose neutrality it guaranteed, and
11826-760: The Ottomans joined the Central Powers in November. Germany's strategy in 1914 was to quickly defeat France, then to transfer its forces to the east, but its advance was halted in September , and by the end of the year the Western Front consisted of a continuous line of trenches stretching from the English Channel to Switzerland. The Eastern Front was more dynamic, but neither side gained a decisive advantage, despite costly offensives. Italy , Bulgaria , Romania , Greece and others joined in from 1915 onward. In April 1917,
11988-598: The Ottomans' territory in the Balkans during the 1912–1913 First Balkan War , much to the surprise of outside observers. The Serbian capture of ports on the Adriatic resulted in partial Austrian mobilisation, starting on 21 November 1912, including units along the Russian border in Galicia . The Russian government decided not to mobilise in response, unprepared to precipitate a war. The Great Powers sought to re-assert control through
12150-655: The Russian Stavka agreed with the French to attack Germany within fifteen days of mobilisation, ten days before the Germans had anticipated, although it meant the two Russian armies that entered East Prussia on 17 August did so without many of their support elements. By the end of 1914, German troops held strong defensive positions inside France, controlled the bulk of France's domestic coalfields, and inflicted 230,000 more casualties than it lost itself. However, communications problems and questionable command decisions cost Germany
12312-631: The Serbian retreat toward the Adriatic coast in the Battle of Mojkovac on 6–7 January 1916, but ultimately the Austrians also conquered Montenegro. The surviving Serbian soldiers were evacuated to Greece. After the conquest, Serbia was divided between Austro-Hungary and Bulgaria. In late 1915, a Franco-British force landed at Salonica in Greece to offer assistance and to pressure its government to declare war against
12474-543: The Soviet Union . Arnold became Chief of the Army Air Forces and acting "Deputy Chief of Staff for Air" with authority over both the Air Corps and Air Force Combat Command (successor to GHQAF). While this provided the air arm with a staff of its own and brought the entire organization under the command of one general, it failed to grant the degree of autonomy sought. By consensus between Marshall and Arnold, debate on separation of
12636-577: The War Department and Air Corps. Their conflict peaked on March 12, 1940, when Arnold's public complaint about increases in shipments brought a personal warning from Roosevelt that "there were places to which officers who did not 'play ball' might be sent, such as Guam ," and got him banished from the White House for eight months. The disfavor shown Arnold by Roosevelt reached a turning point in March 1941 when new Secretary of War Henry L. Stimson ,
12798-564: The Washington environment, all of which would help him as head of the military's air services. When the Division of Military Aeronautics superseded the Air Division in April 1918, Arnold continued as executive assistant to its director, Major General William Kenly , and advanced to assistant director when the DMA was removed from the Signal Corps in May 1918. Arnold's third child, William Bruce Arnold,
12960-629: The West was very successful. By the end of August, the Allied left, which included the British Expeditionary Force (BEF), was in full retreat , and the French offensive in Alsace-Lorraine was a disastrous failure, with casualties exceeding 260,000. German planning provided broad strategic instructions while allowing army commanders considerable freedom in carrying them out at the front, but von Kluck used this freedom to disobey orders, opening
13122-739: The Western Department (after June 1920 the Ninth Corps Area ) in San Francisco and de facto commander of Crissy Field , being developed on a site determined by a board chaired by Arnold. Arnold's promotion to colonel expired June 30, 1920, and he reverted to his permanent establishment rank of captain. Even though he received an automatic promotion to major because of his Military Aviator rating, he became junior to officers serving under him, including Spaatz, whose promotion received while in France
13284-768: The White House was secure." His importance to Roosevelt in setting an airpower agenda was demonstrated when Arnold was invited to the Atlantic Conference in Newfoundland in August, the first of seven such summits that he, not Morgenthau, would attend. The division of authority between the Air Corps and the GHQ Air Force was removed with promulgation of Army Regulation 95–5, creating the United States Army Air Forces on June 20, 1941, only two days before Germany's invasion of
13446-480: The Younger . Under Schlieffen, 85% of German forces in the west were assigned to the right wing, with the remainder holding along the frontier. By keeping his left-wing deliberately weak, he hoped to lure the French into an offensive into the "lost provinces" of Alsace-Lorraine , which was the strategy envisaged by their Plan XVII . However, Moltke grew concerned that the French might push too hard on his left flank and as
13608-446: The aggressor, German Chancellor Bethmann Hollweg delayed the commencement of war preparations until 31 July. That afternoon, the Russian government were handed a note requiring them to "cease all war measures against Germany and Austria-Hungary" within 12 hours. A further German demand for neutrality was refused by the French who ordered general mobilization but delayed declaring war. The German General Staff had long assumed they faced
13770-400: The air was diffused and turned 90 degrees rearwards, before entering a set of ten reverse-flow combustion chambers (i.e. cans). A relatively short shaft connected the compression system to the single stage axial turbine. After expansion through the turbine, the combustion products exhausted the engine through the simple conical propelling nozzle, via the jet-pipe. For the turbine section, GE used
13932-413: The amputation of three fingertips on his left hand in 1922. His wife and sons also experienced serious health problems, including a near fatal case of scarlet fever for son Bruce. His fourth child, John Linton Arnold, born in the summer of 1921, died on June 30, 1923, of acute appendicitis . Both Arnold and wife Bee needed almost a year to recover psychologically from the loss. In August 1924, Arnold
14094-750: The arrangement. The VLR program had been plagued with a seemingly unending series of development problems, subjecting it and Arnold to much criticism in the press and from skeptical field commanders. The B-29 was the key component of the AAF's fourth strategic priority, since no other land-based bomber was capable of reaching the Japanese homeland, but by February 1944, the XX Bomber Command , slated to begin Operation Matterhorn on June 1, had virtually no flight time yet above an altitude of 20,000 feet (6,100 m). World War I World War I or
14256-466: The attack by the Austro-Hungarian army under Mackensen's army of 250,000 that was already underway. Serbia was conquered in a little more than a month, as the Central Powers, now including Bulgaria, sent in 600,000 troops in total. The Serbian army, fighting on two fronts and facing certain defeat, retreated into northern Albania . The Serbs suffered defeat in the Battle of Kosovo . Montenegro covered
14418-535: The best way of achieving this. However, the Foreign Ministry had no solid proof of Serbian involvement. On 23 July, Austria delivered an ultimatum to Serbia, listing ten demands made intentionally unacceptable to provide an excuse for starting hostilities. Serbia ordered general mobilization on 25 July, but accepted all the terms, except for those empowering Austrian representatives to suppress "subversive elements" inside Serbia, and take part in
14580-479: The board's report concluded that airpower was indispensable to the defense of the hemisphere, stressed the need for long-range bombers, and became the basis for the first Air Corps field manual , it was a "considerable attenuation" of the doctrine being developed at the Air Corps Tactical School . Arnold submitted the findings to George C. Marshall, newly appointed as chief of staff, on September 1, 1939,
14742-483: The border and pre-empt such a move. To avoid violating Belgian neutrality, he was told any advance could come only after a German invasion. Instead, the French cabinet ordered its Army to withdraw 10 km behind the German frontier, to avoid provoking war. On 2 August, Germany occupied Luxembourg and exchanged fire with French units when German patrols entered French territory; on 3 August, they declared war on France and demanded free passage across Belgium, which
14904-583: The campaign saw the first use of anti-aircraft warfare after an Austrian plane was shot down with ground-to-air fire, as well as the first medical evacuation by the Serbian army. Upon mobilisation, in accordance with the Schlieffen Plan , 80% of the German Army was located on the Western Front, with the remainder acting as a screening force in the East. Rather than a direct attack across their shared frontier,
15066-636: The capital of the recently annexed Bosnia and Herzegovina . Cvjetko Popović , Gavrilo Princip , Nedeljko Čabrinović , Trifko Grabež , Vaso Čubrilović ( Bosnian Serbs ) and Muhamed Mehmedbašić (from the Bosniaks community), from the movement known as Young Bosnia , took up positions along the Archduke's motorcade route, to assassinate him. Supplied with arms by extremists within the Serbian Black Hand intelligence organisation, they hoped his death would free Bosnia from Austrian rule. Čabrinović threw
15228-466: The chance of a decisive outcome, while it had failed to achieve the primary objective of avoiding a long, two-front war. As was apparent to several German leaders, this amounted to a strategic defeat; shortly after the First Battle of the Marne , Crown Prince Wilhelm told an American reporter "We have lost the war. It will go on for a long time but lost it is already." On 30 August 1914, New Zealand occupied German Samoa (now Samoa ). On 11 September,
15390-563: The consequence of which was a mutual dislike with Patrick. Arnold was sent to Rockwell Field on January 10, 1919, as District Supervisor, Western District of the Air Service, to oversee the demobilization of 8,000 airmen and surplus aircraft. There he first established relationships with the men who became his main aides, executive officer Captain Carl A. Spaatz and adjutant 1st Lieutenant Ira C. Eaker . Five months later Arnold became Air Officer of
15552-511: The cost of 199 submarines. World War I also saw the first use of aircraft carriers in combat, with HMS Furious launching Sopwith Camels in a successful raid against the Zeppelin hangars at Tondern in July 1918, as well as blimps for antisubmarine patrol. Faced with Russia in the east, Austria-Hungary could spare only one-third of its army to attack Serbia. After suffering heavy losses,
15714-513: The creation of new independent states, including Poland , Finland , the Baltic states , Czechoslovakia , and Yugoslavia . The League of Nations was established to maintain world peace, but its failure to manage instability during the interwar period contributed to the outbreak of World War II in 1939. Before World War II , the events of 1914–1918 were generally known as the Great War or simply
15876-449: The creation of strong defensive systems largely impervious to massed infantry advances, such as barbed wire , machine guns and above all far more powerful artillery , which dominated the battlefield and made crossing open ground extremely difficult. Both sides struggled to develop tactics for breaching entrenched positions without heavy casualties. In time, technology enabled the production of new offensive weapons, such as gas warfare and
16038-946: The crowds listened to music and drank wine, as if nothing had happened." Nevertheless, the impact of the murder of the heir to the throne was significant, and has been described by historian Christopher Clark as a "9/11 effect, a terrorist event charged with historic meaning, transforming the political chemistry in Vienna". Austro-Hungarian authorities encouraged subsequent anti-Serb riots in Sarajevo . Violent actions against ethnic Serbs were also organised outside Sarajevo, in other cities in Austro-Hungarian-controlled Bosnia and Herzegovina, Croatia and Slovenia. Austro-Hungarian authorities in Bosnia and Herzegovina imprisoned approximately 5,500 prominent Serbs, 700 to 2,200 of whom died in prison. A further 460 Serbs were sentenced to death. A predominantly Bosniak special militia known as
16200-503: The day Nazi Germany invaded Poland . When Marshall requested a reorganization study from the Air Corps, Arnold submitted a proposal on October 5, 1940, that would create an air staff, unify the air arm under one commander, and grant it autonomy with the ground and supply forces. Congress repealed the Neutrality Act in November 1939 to permit the selling of aircraft to the belligerents, causing Arnold concern that shipments of planes to
16362-491: The drinking rumors, but more recent research asserts that Craig threatened to resign as Army chief of staff if Arnold was not appointed. President Franklin D. Roosevelt appointed Arnold as Chief of Air Corps on September 29, which carried with it the rank of major general . To repair his relationship with the Andrews faction, most of whom were part of GHQ Air Force, he selected its chief of staff, Colonel Walter G. Kilner, to fill
16524-622: The expansion of the French colonial empire . In 1873, Bismarck negotiated the League of the Three Emperors , which included Austria-Hungary , Russia and Germany. After the 1877–1878 Russo-Turkish War , the League was dissolved due to Austrian concerns over the expansion of Russian influence in the Balkans , an area they considered to be of vital strategic interest. Germany and Austria-Hungary then formed
16686-432: The first radio telegraph message, at a distance of 6 miles (9.7 km), from an aircraft to a receiver on the ground, manned by 1st Lt. Joseph O. Mauborgne of the Signal Corps. Three days later, Arnold flew on an artillery spotting exercise with 1st Lieutenant Alfred L.P. Sands of the 6th Field Artillery as an observer. Spiraling down to land in S.C. No. 10, the plane stalled, went into a spin, and they narrowly avoided
16848-400: The first time on the Western Front. Several types of gas soon became widely used by both sides and though it never proved a decisive, battle-winning weapon, it became one of the most feared and best-remembered horrors of the war. In February 1916, the Germans attacked French defensive positions at the Battle of Verdun , lasting until December 1916. Casualties were greater for the French, but
17010-577: The flight in writing, Arnold was sent to Panama on January 30, 1917, one day after the birth of his second child, Henry H. Arnold Jr. Arnold collected the men who would make up his first command, the 7th Aero Squadron , in New York City on February 5, 1917, and was ordered to find a suitable location for an airfield in the Panama Canal Zone . When the military in Panama could not agree on a site, Arnold
17172-586: The front. Serbian and French troops finally made a breakthrough in September 1918 in the Vardar offensive , after most German and Austro-Hungarian troops had been withdrawn. The Bulgarians were defeated at the Battle of Dobro Pole , and by 25 September British and French troops had crossed the border into Bulgaria proper as the Bulgarian army collapsed. Bulgaria capitulated four days later, on 29 September 1918. The German high command responded by despatching troops to hold
17334-526: The globe, some of which were subsequently used to attack Allied merchant shipping . These were systematically hunted down by the Royal Navy, though not before causing considerable damage. One of the most successful was the SMS ; Emden , part of the German East Asia Squadron stationed at Qingdao , which seized or sank 15 merchantmen, a Russian cruiser and a French destroyer. Most of the squadron
17496-465: The grandiose-sounding but tiny 1st Wing , on November 27, 1931. Arnold's responsibilities included refurbishing the base into a showcase installation, which required that he resolve strained relations with the community. He accomplished this by having his officers join local social service organizations and by a series of well-publicized relief efforts. Arnold took command of the 1st Wing himself on January 4, 1933, which flew food-drops during blizzards in
17658-534: The high ground, while their trenches tended to be better built; those constructed by the French and English were initially considered "temporary", only needed until an offensive would destroy the German defences. Both sides tried to break the stalemate using scientific and technological advances. On 22 April 1915, at the Second Battle of Ypres , the Germans (violating the Hague Convention ) used chlorine gas for
17820-435: The introductions of tanks and aircraft . World War I was one of the deadliest conflicts in history , resulting in an estimated 10 million military dead and more than 20 million wounded , plus some 10 million civilian dead from causes including genocide . The movement of large numbers of people was a major factor in the deadly Spanish flu pandemic. The causes of World War I included the rise of Germany and decline of
17982-467: The investigation and trial of Serbians linked to the assassination. Claiming this amounted to rejection, Austria broke off diplomatic relations and ordered partial mobilisation the next day; on 28 July, they declared war on Serbia and began shelling Belgrade . Russia ordered general mobilization in support of Serbia on 30 July. Anxious to ensure backing from the SPD political opposition by presenting Russia as
18144-425: The largest and most powerful air force in the world. An advocate of technological research and development , his tenure saw the development of the intercontinental bomber, the jet fighter, the extensive use of radar , global airlift and atomic warfare as mainstays of modern air power. Arnold's most widely used nickname, "Hap", was short for "Happy", attributed variously to work associates when he moonlighted as
18306-486: The leads in The Military Air-Scout and The Elopement . The flight school moved in November 1911 to a farm leased near Augusta , Georgia , hoping to continue flying there during the winter. Training was limited by rain and flooding, and they returned to Maryland in May 1912. Arnold began to develop a phobia about flying, intensified by Al Welsh's fatal crash at College Park on June 11. In August Arnold
18468-491: The middle and the lower end of his class, with his better scores in mathematics and science. He wanted assignment to the Cavalry but an inconsistent demerit record and a cumulative general merit class standing of 66th out of 111 cadets resulted in his being commissioned on June 14, 1907, as a second lieutenant , Infantry . He initially protested the assignment (there was no commissioning requirement for USMA graduates in 1907), but
18630-534: The mirage, looking for the perfect airplane, to a point where fighting squadrons are deficient in numbers of fighting planes." To that end he concentrated on rapid returns from R&D investments, exploiting proven technologies to provide operational solutions to counter the rising threat of the Axis Powers. Arnold also pushed for jet propulsion, especially after the British shared their plans of Whittle 's turbojet during his visit to Britain in April 1941. The proposal
18792-644: The modern use of water dropping aircraft.) Of Arnold, the National Park Service history of Crissy Field wrote: "During his tour of duty, Arnold had been instrumental both in bringing Crissy Field into existence, and establishing the pattern of its operations." In October 1922 he was sent back to Rockwell, now a service depot, as base commander and there encouraged an aerial refueling , the first in history, that took place eight months later. Arnold experienced several serious illnesses and accidents requiring hospitalization, including recurring stomach ulcers and
18954-465: The natural choice for producing such an engine. The initial prototype, the General Electric I-A , was essentially based on the W.2B/23. It first ran on 18 April 1942 and developed a static thrust of 1250lbf. The I-A air intake consisted of two peripheral slots which led to a double-sided, centrifugal compressor. A series of vanes guided the air into the impeller eyes. After radial compression,
19116-665: The new head of the Aeronautical Division in the Office of the Chief Signal Officer in Washington, D.C. In the spring he was assigned the task of closing the flying school at College Park. Although promoted to 1st lieutenant on April 10, 1913, Arnold was unhappy and requested a transfer to the Philippines. While awaiting a response, he received orders to the 9th Infantry on July 10. In August, still awaiting transfer, he testified before
19278-460: The ocean, even to neutral ships. Since there was limited response to this tactic, Germany expected a similar response to its unrestricted submarine warfare. The Battle of Jutland in May/June 1916 was the only full-scale clash of battleships during the war, and one of the largest in history. The clash was indecisive, though the Germans inflicted more damage than they received; thereafter the bulk of
19440-531: The other airmen who took part, but the deputy chief of staff ignored his recommendations. His reputation among some of his peers was tarnished by resentment when he was belatedly awarded the Distinguished Flying Cross for the flight in 1937. On March 1, 1935, General Headquarters Air Force was activated to control all combat aviation units of the Air Corps based in the United States, although it
19602-451: The political struggles over them from the Foulois years. In effect, however, Arnold had "switched sides" in the struggle between GHQ Air Force and the Air Corps. Westover was killed in an air crash at Burbank, California , on September 21, 1938. Prior vacancies in the office had been filled by an incumbent assistant chief, and Arnold's appointment to succeed Westover seemed automatic since he
19764-585: The production of aircraft for use by other allies. AWPD/42 reaffirmed earlier strategic priorities, but increased the list of industrial targets from 23 to 177, ranking the German Luftwaffe first and its submarine force second in importance of destruction. It also directed that the B-29 bomber not be employed in Europe because of problems in its development, but instead that the B-29 program's deployment be concentrated in
19926-733: The protection of the " cruiser rules ", which demanded warning and movement of crews to "a place of safety" (a standard that lifeboats did not meet). Finally, in early 1917, Germany adopted a policy of unrestricted submarine warfare , realising the Americans would eventually enter the war. Germany sought to strangle Allied sea lanes before the United States could transport a large army overseas, but, after initial successes, eventually failed to do so. The U-boat threat lessened in 1917, when merchant ships began travelling in convoys , escorted by destroyers . This tactic made it difficult for U-boats to find targets, which significantly lessened losses; after
20088-404: The relief of a friend or protégé, was just one of many that exemplified a ruthlessness Arnold developed to get results. In 1942, Brigadier General Walter R. Weaver , acting chief of the Air Corps, had his job eliminated and was relegated to a technical training command. George C. Kenney relieved Jacob E. Fickel in command of Fourth Air Force and later that same year replaced former Chief of
20250-470: The same day. The Air Service separated from the Signal Corps on May 20, 1918. However control of aviation remained with the ground forces when its post-war director was a field artillery general, Major General Charles T. Menoher , who epitomized the view of the War Department General Staff that "military aviation can never be anything other than simply an arm of the (Army)". Menoher
20412-588: The size of his small bombing force. Heavy losses in the summer and fall of 1943 on deep penetration missions intensified Eaker's requests. Arnold, under pressure and impatient for results, ignored Eaker's findings and placed the blame on a lack of aggressiveness by bomber commanders. This came at a time when General Dwight D. Eisenhower was putting together his command group for the invasion of Europe , and Arnold approved Eisenhower's request to replace Eaker with his own commanders, Spaatz and Doolittle. The change in command at Eighth Air Force, particularly involving
20574-464: The term First World War was in September 1914 by German biologist and philosopher Ernst Haeckel who stated, "There is no doubt that the course and character of the feared 'European War' ... will become the first world war in the full sense of the word." For much of the 19th century, the major European powers maintained a tenuous balance of power , known as the Concert of Europe . After 1848, this
20736-682: The threat posed by the closing of this gap was more important than competing with the Royal Navy. After Germany expanded its standing army by 170,000 troops in 1913, France extended compulsory military service from two to three years; similar measures were taken by the Balkan powers and Italy, which led to increased expenditure by the Ottomans and Austria-Hungary. Absolute figures are difficult to calculate due to differences in categorising expenditure since they often omit civilian infrastructure projects like railways which had logistical importance and military use. It
20898-516: The visit was the setting up of a program for training British pilots in the US, which subsequently became known as the Arnold Scheme . Arnold's meeting with Roosevelt to report his findings was judged as impressively cogent and optimistic, but the president ruminated on Arnold's future for three weeks before submitting his name and the others to the Senate. From that point on, however, Arnold's "position in
21060-577: The war ended with the Armistice of 11 November 1918 . The Paris Peace Conference of 1919–1920 imposed settlements on the defeated powers, most notably the Treaty of Versailles , by which Germany lost significant territories, was disarmed, and was required to pay large war reparations to the Allies. The dissolution of the Russian, German, Austro-Hungarian, and Ottoman Empires redrew national boundaries and resulted in
21222-581: The war involved British, French, and German colonial forces in Africa. On 6–7 August, French and British troops invaded the German protectorates of Togoland and Kamerun . On 10 August, German forces in South-West Africa attacked South Africa; sporadic and fierce fighting continued for the rest of the war. The German colonial forces in German East Africa , led by Colonel Paul von Lettow-Vorbeck , fought
21384-410: The war, Arnold was promoted to lieutenant general on December 15, 1941. On March 9, 1942, after the creation of the AAF failed to define clear channels of authority for the air forces, the Army adopted the functional reorganization that Arnold had advocated in October 1940. Acting on an executive order from Roosevelt, the War Department granted the AAF full autonomy, equal to and entirely separate from
21546-418: The west , which despite initial successes left the German Army exhausted and demoralised. A successful Allied counter-offensive from August 1918 caused a collapse of the German front line. By early November, Bulgaria, the Ottoman Empire and Austria-Hungary had each signed armistices with the Allies, leaving Germany isolated. Facing a revolution at home , Kaiser Wilhelm II abdicated on 9 November, and
21708-423: The winter of 1932–33, assisted in relief work during the Long Beach earthquake of March 10, 1933, and established camps for 3,000 boys of the Civilian Conservation Corps . He organized a high-profile series of aerial reviews that featured visits from Hollywood celebrities and aviation notables. In August 1932, Arnold began acquisition of portions of Rogers Dry Lake as a bombing and gunnery range for his units,
21870-579: The year before and with the depression afflicting his father after her death. A contemporary biographer of Arnold notes that not until after his mother's funeral did Bee begin use of the sobriquet "Hap" in place of "Sunny" when addressing him, apparently to avoid the "constant reminder" of his mother that the latter name might bring. Arnold himself eschewed the use of "Sunny" in his personal correspondence after May 1931, signing himself as "Hap" Arnold from that point forward. Arnold took command of March Field , California , where Spaatz had just assumed command of
22032-428: The year." Arnold won when he located a company of cavalry from the air and returned safely despite strong turbulence. As a result, he and Milling were sent to Fort Riley , Kansas , to experiment with radio and other communications from the air with the field artillery . Arnold's flight on November 2 in Wright C Speed Scout S.C. Number 10, with 1st Lieutenant Follett Bradley as his wireless operator, successfully sent
22194-468: Was "fun-loving and prone to laughter," and not rigid in her beliefs. When Arnold was eleven, his father responded to the Spanish–American War by serving as a surgeon in the Pennsylvania National Guard , of which he remained a member for the next 24 years. Arnold attended Lower Merion High School in Ardmore, Pennsylvania , graduating in 1903. The athletic fields at Lower Merion are named after him. Arnold had no intention of attending West Point (he
22356-414: Was also the founder of Project RAND, which evolved into one of the world's largest non-profit global policy think tanks, the RAND Corporation , and was one of the founders of Pan American World Airways . Instructed in flying by the Wright Brothers , Arnold was one of the first military pilots worldwide, and one of the first three rated pilots in the history of the United States Air Force . He overcame
22518-407: Was an American general officer holding the ranks of General of the Army and later, General of the Air Force . Arnold was an aviation pioneer, Chief of the Air Corps (1938–1941), commanding general of the United States Army Air Forces , the only United States Air Force general to hold five-star rank, and the only officer to hold a five-star rank in two different U.S. military services. Arnold
22680-491: Was assigned to a company at Fort Thomas, Kentucky , on September 1, where he was stationed until transferred to the 13th Infantry on November 1. On September 10, 1913, he and Bee married, with Milling acting as his best man . Sent back to the Philippines in January 1914, he was quartered near 1st Lieutenant George C. Marshall , who became his mentor, friend and patron. Soon after their arrival Bee miscarried, but on January 17, 1915, their first child, Lois Elizabeth Arnold,
22842-463: Was at Marblehead, Massachusetts , with 1st Lieutenant Roy C. Kirtland conducting acceptance tests of the Burgess Model H , an enclosed-fuselage tandem-seat seaplane and the Army's first tractor (front-mounted propeller and engine). The pair received orders to fly the new aircraft to Bridgeport, Connecticut , to participate in maneuvers but high winds forced them to land on Massachusetts Bay on August 12. Attempting to take off again, Arnold caught
