The United States Army Air Service ( USAAS ) (also known as the "Air Service" , "U.S. Air Service" and before its legislative establishment in 1920, the "Air Service, United States Army" ) was the aerial warfare service component of the United States Army between 1918 and 1926 and a forerunner of the United States Air Force . It was established as an independent but temporary branch of the U.S. War Department during World War I by two executive orders of President Woodrow Wilson : on May 24, 1918, replacing the Aviation Section, Signal Corps as the nation's air force; and March 19, 1919, establishing a military Director of Air Service to control all aviation activities. Its life was extended for another year in July 1919, during which time Congress passed the legislation necessary to make it a permanent establishment. The National Defense Act of 1920 assigned the Air Service the status of " combatant arm of the line " of the United States Army with a major general in command.
147-621: The III Corps Observation Group was a United States Army Air Service unit that fought on the Western Front during World War I as part of the Air Service, First United States Army . It was demobilized on 12 May 1919. There is no modern United States Air Force unit that shares its lineage and history. The III Corps Observation Group was organized on 20 September 1918 by the First Army Air Service at Souilly Aerodrome , France. It

Kenly brought back from France to be its head, to separate supervision of aviation from the duties of the Chief Signal Officer. Less than a month later, Wilson used a war powers provision of the Overman Act of May 20, 1918, to issue Executive Order No. 2862 that suspended for

The 1st also won the Airplane photographic race competition, in which in 31 minutes the squadron took areal photos of a specified area and dropped developed and printed photos. The flight time from Coblenz to Weißenthurm was 31 minutes. The 1st also won honors in

Not long before Tulla went to work on widening and straightening the river, heavy floods caused significant loss of life. Four diplomatic treaties were signed among German state governments and French regions dealing with
735-535: A final plan for 202 by June 1919. In Pershing's view, the two functions of the AEF's Air Service were to repel German aircraft and conduct observation of enemy movements. The heart of the proposed force would be its 101 observation squadrons (52 corps observation and 49 army observation), to be distributed to three armies and 16 corps. In addition, 60 pursuit squadrons, 27 night-bombardment squadrons, and 14 day-bombardment squadrons were to conduct supporting operations. Without
882-489: A highly publicized personal investigation by Gutzon Borglum , a harshly vocal critic of the board. Borglum had exchanged letters with President Wilson, a personal friend, from which he assumed an appointment to investigate had been authorized, which the administration soon denied. Both the U.S. Senate and the Department of Justice began investigations into possible fraudulent dealings. President Wilson also acted by appointing
1029-635: A message dropping contest, making a ground drop of written observation from an aircraft at 500m altitude 10 yards from a panel. It also displayed its Radio Section which showed the methods of liaison from ground to air and air to ground employed by the Air Service during the War. On 12 May 1919 orders were received from Third Army for all squadrons of the Group to report to the Services of Supply 1st Air Depot, at Colombey-les-Belles Airdrome to demobilize for immediate return to
1176-515: A permanent part of the air forces. Observation planes often operated individually, as did pursuit pilots to attack a balloon or to meet the enemy in a dogfight . However the tendency was toward formation flying, for pursuit as well as for bombardment operations, as a defensive tactic. The dispersal of squadrons among the army ground units (each corps and division had an observation squadron attached) made coordination of air activities difficult, so that squadrons were organized by functions into groups ,
1323-656: A predominantly westerly direction and flows into the Netherlands where it eventually empties into the North Sea . It drains an area of 9,973 km . Its name derives from the Celtic Rēnos . There are two German states named after the river, North Rhine-Westphalia and Rhineland-Palatinate , in addition to several districts (e.g. Rhein-Sieg ). The departments of Bas-Rhin and Haut-Rhin in Alsace (France) are also named after
1470-874: A separate aviation department to act as the centralized authority for decision-making, both the War and the Navy Departments opposed it, and on October 1, 1917, Congress instead legalized the existence of the APB and changed its name to the " Aircraft Board ", transferring its functions from the Council of National Defense to the secretaries of War and the Navy. Even so, the Aircraft Board in practice had little control over procurement contracts and functioned mostly as an information provider between industrial, governmental, and military entities. Nor did
1617-531: A separate executive bureau to provide the aircraft needed. This arrangement lasted only until the War Department implemented the executive order on May 24 by issuing General Order No. 51 to coordinate the two independent agencies, with an eventual goal of creating a Director of Air Service . (The term "Air Service" had been in use in France since June 13, 1917, to describe the function of aviation units attached to

By the time the bill passed, the term Air Service was in widespread if unofficial usage to collectively describe all aspects of Army aviation. Although it considered creation of
1911-533: A total of 1,146 sorties and a total of 1,111 combat hours and 3 minutes. The 90th Aero Squadron shot down 7 enemy aircraft and the 88th three. Twenty-five successful artillery adjustments were made by the observations performed by the group. Also Thousands of sheets of leaflets were dropped on enemy forces. During the weeks following the signing of the Armistice, the III Corps Observation Group would be

In Alemannic, the deletion of the ending -n in pausa is a recent development; the form Rn is largely preserved in Lucernese dialects. Rhing in Ripuarian is diphthongized, as is Rhei, Rhoi in Palatine . While Spanish has adopted the Germanic vocalism Rin- , Italian, Occitan, and Portuguese have retained

The "total length of the Rhine", to the inclusion of Lake Constance and the Alpine Rhine is more difficult to measure objectively; it was cited as 1,232 kilometers (766 miles) by the Dutch Rijkswaterstaat in 2010. Its course is conventionally divided as follows: The Rhine carries its name without distinctive accessories only from
2499-750: Is sometimes called Rhinesee ("Lake Rhine"). Besides the Seerhein , the Radolfzeller Aach is the main tributary of Untersee . It adds large amounts of water from the Danube system to the Untersee via the Danube Sinkhole . Reichenau Island was formed at the same time as the Seerhein, when the water level fell to its current level. Lake Untersee is part of the border between Switzerland and Germany , with Germany on

The Rhine and the Danube comprised much of the Roman Empire 's northern inland boundary , and the Rhine has been a vital navigable waterway bringing trade and goods deep inland since those days. The various castles and defenses built along it attest to its prominence as
2793-601: The 94th Pursuit Squadron scored. The first mission by an American squadron across the lines occurred April 11, when the 1st Aero Squadron, led by its commander, Major Ralph Royce , flew a photo reconnaissance mission to the vicinity of Apremont . The first American balloon group arrived in France on December 28, 1917. It separated into four companies that were assigned individually to training centers and instructed in French balloon procedures, then equipped with Caquot balloons, winches, and parachutes. The 2d Balloon Company joined
2940-518: The Aare . The Aare more than doubles the Rhine's water discharge, to an average of slightly more than 1,000 m /s (35,000 cu ft/s), and provides more than a fifth of the discharge at the Dutch border. The Aare also contains the waters from the 4,274 m (14,022 ft) summit of Finsteraarhorn , the highest point of the Rhine basin . Between Eglisau and Basel , the vast majority of its length,

This section is nearly 86 km long, and descends from a height of 599 meters to 396 meters. It flows through a wide glacial Alpine valley known as the Rhine Valley ( German : Rheintal ). Near Sargan a natural dam, only a few meters high, prevents it from flowing into

At the assurance of the French that they could be rapidly trained in all phases, 1,700 cadets who had graduated from ground school were sent to Europe to undertake the entire flying portion of their training in Great Britain , France , and Italy . In December 1917, after receiving 1,400 of

Miller, commanding the 95th Pursuit Squadron , was shot down while on a voluntary patrol near Reims . The first aerial victory in an American unit was by 1st Lt. Paul F. Baer of the 103rd Aero Squadron, and formerly a member of the Lafayette Flying Corps, on March 11. The first victories credited to American-trained pilots came on April 14, 1918, when Lieutenants Alan F. Winslow and Douglas Campbell of

For most of its length, the Seerhein forms the border between Germany and Switzerland. The exception is the old city center of Konstanz, on the Swiss side of the river. The Seerhein emerged in the last thousands of years, when erosion caused

Legally, the Central Bridge is the boundary between High and Upper Rhine. The river now flows north as Upper Rhine through the Upper Rhine Plain , which is about 300 km long and up to 40 km wide. The most important tributaries in this area are the Ill below of Strasbourg,

On the few remaining natural sections, there are still several rapids . Over its entire course from Lake Constance to the Swiss border at Basel the river descends from 395 m to 252 m. In the center of Basel, the first major city in the course of the stream, is
4116-723: The canton of Ticino is drained by the Reno di Medel , which crosses the geomorphologic Alpine main ridge from the south. All streams in the source area are partially, sometimes completely, captured and sent to storage reservoirs for the local hydro-electric power plants. The culminating point of the Anterior Rhine's drainage basin is the Piz Russein of the Tödi massif of the Glarus Alps at 3,613 meters (11,854 ft) above sea level. It starts with

Though individual areas within the aviation industry responded well, the industry as a whole failed. Efforts to mass-produce European aircraft under license largely failed because the aircraft, made by hand, were not amenable to
4557-643: The "Equipment Division" of the Signal Corps exercise such control. Established by the Office of the Chief Signal Officer (OCSO) as one of the operating components of the Aviation Section, its task was to unify and coordinate the various agencies involved but its head was a commissioned former member of the APB who did nothing to create any effective coordination. Moreover, the largely wood and fabric airframe designs of World War I did not lend themselves to being made with

4704-480: The "Million-Dollar Guard". The backlog was finally cleared by opening an Air Service primary school at Tours and devoting part of the advanced school at Issoudun to preliminary training for a period of time. The U.S. training program produced more than 10,000 pilots as new first lieutenants in the Signal Officers Reserve Corps (S.O.R.C.). 8,688 received ratings of Reserve Military Aviator in

While it was slightly modified during the Roman occupation, it was not until the emergence of engineers such as Johann Gottfried Tulla that significant modernization efforts changed the shape of the river. Earlier work under Frederick the Great surrounded efforts to ease shipping and construct dams to serve coal transportation. Tulla is considered to have domesticated the Upper Rhine,
4998-419: The 1st Pursuit Group of four pursuit squadrons relocated from Selfridge Field, Michigan, to add their weight to the effort. Collectively the three groups (the entire combat strength of the Air Service in the continental United States) comprised the 1st Wing . In January 1920 only the surveillance group continued the patrols, which gradually diminished until June 1921 when they ceased entirely. Another group
5145-580: The 3rd and 4th Regiments reorganized, delaying their deployment until the end of July. By the Armistice all four regiments were configured as aircraft repair and maintenance units, and designated Air Service Mechanics Regiments . The primary aircraft used by the AEF at the front (the "Zone of Advance") were the SPAD XIII (877), Nieuport 28 (181), and SPAD VII (103) as pursuit aircraft, the DeHaviland DH-4B (696) and Breguet 14 (87) for daylight bombing, and

The aircraft were also, when deemed appropriate communicate directly with Brigade Commanders, with the brigades establishing suitable message dropping locations along their line of march. The greatest attention by the Brigades were the manipulation of panels so the air service could render effective aid when called for. Also,
5439-533: The 9th Observation, was formed. The 7th Bombardment and 8th Fighter Groups were designated but not activated until the end of the decade. Sect. 13a. There is hereby created an Air Service. The Air Service shall consist of one Chief of Air Service with the rank of major-general, one assistant with the rank of brigadier-general, 1,514 officers in grades from colonel to second lieutenant, inclusive, and 16,000 enlisted men, including not to exceed 2,500 flying cadets... — Section 13a, Public Law 242, 41 Stat . 759 With

Mitchell was replaced in January as commander of the Third Army Air Service by Col. Harold Fowler , a combat veteran of the Royal Flying Corps and former commander of the American 17th Pursuit Squadron. On April 15, 1919, the Second Army Air Service in France also closed down. Its former air units were transferred to
5733-550: The Air Service Concentration Barracks at Saint-Maixent received all newly arrived Air Service troops, distributing them to 26 training fields and schools throughout the central and western regions of the country. Flying training schools, equipped with 2,948 airplanes, supplied 1,674 fully trained pilots and 851 observers to the Air Service, with 1,402 pilots and 769 observers serving at the front. The observers trained in France included 825 artillery officers from
5880-405: The Air Service branch, receiving new commissions. During the war its responsibilities and functions were split between two coordinate agencies, the Division of Military Aeronautics (DMA) and the Bureau of Aircraft Production (BAP), each reporting directly to the Secretary of War, creating a dual authority over military aviation that caused unity of command difficulties. The seven-year history of

6174-631: The Air Service destroyed 756 enemy aircraft and 76 balloons in combat. 17 balloon companies also operated at the front, making 1,642 combat ascensions. 289 airplanes and 48 balloons were lost in battle. The Air Service was the first form of the air force to have an independent organizational structure and identity. Although officers concurrently held rank in various branches, after May 1918 their branch designation in official correspondence while on aviation assignment changed from "ASSC" (Aviation Section, Signal Corps) to "AS, USA" (Air Service, United States Army). After July 1, 1920, its personnel became members of
6321-473: The Air Service of the American Expeditionary Force , a separate entity under commanding General John J. Pershing that conducted the combat operations of U.S. military aviation, began field service in the spring of 1918. By the end of the war, the Air Service used 45 squadrons to cover 137 kilometers (85 miles) of front from Pont-à-Mousson to Sedan . 71 pursuit pilots were credited with shooting down five or more German aircraft while in American service. Overall

A Chief of Air Service was authorized with the rank of major general to replace the previous Director of Air Service , and an assistant chief created in the rank of brigadier general (from 1920 to 1925 this position
6615-412: The Air Service was accomplished within a year. By November 22, 1919, the Air Service had been reduced to one construction, one replacement, and 22 flying squadrons; 32 balloon companies; 15 photographic sections; and 1,168 officers and 8,428 enlisted men. The combat strength of the Air Service was only four pursuit and four bombardment squadrons. Although the leaders of the reorganized Air Service persuaded
6762-402: The Air Service was housed in the Munitions Building in Washington, D.C., and consisted of an executive staff including the chiefs of the Finance and Medical Sections, and four divisions, each administered by a chief: Personnel Group, Information Group (Intelligence), Training and War Plans Group, and Supply Group. Rhine River The Rhine ( / r aɪ n / RYNE ) is one of

In all, 211 squadrons of all types trained in Great Britain, with 71 arriving in France before the Armistice. At its peak establishment in November 1918, the Air Service was based at 31 stations in the Services of Supply (rear areas) and 78 aerodromes in the Zone of Advance (combat area). The 740 combat airplanes equipping

Arnold , Assistant Director of the DMA, was ordered to put together a daily route for moving mail by airplane between New York City , Philadelphia , and Washington, D.C. He assigned the task to the Executive Officer for Flying Training, Major Reuben H. Fleet . The Air Service, using six pilots (four instructor pilots and two new graduates) and six Curtiss JN-4H "Jenny" trainers modified to carry mail, began

In August, the Senate completed its investigation of the Aircraft Board, and while it found no criminal culpability, it reported that massive waste and delay in production had occurred. As a result, the Director of Aircraft Production (who was also chairman of the Aircraft Board), John D. Ryan,

Of aircraft manufactured in America, the de Havilland DH-4B (3,400) was the most numerous, although only 1,213 were shipped overseas, and only 1,087 of those assembled, most used in observation units. The facilities of the Air Service in the United States totaled 40 flying fields, 8 balloon fields, 5 schools of military aeronautics, 6 technical schools, and 14 aircraft depots. 16 additional training schools were located in France, and officers also trained at three schools operated by
7497-424: The Anterior Rhine and the Rhine as a whole. The Posterior Rhine rises in the Rheinwald below the Rheinwaldhorn . The source of the river is generally considered north of Lai da Tuma/Tomasee on Rein Anteriur/Vorderrhein , although its southern tributary Rein da Medel is actually longer before its confluence with the Anterior Rhine near Disentis . The Anterior Rhine arises from numerous source streams in

The Air Service was renamed the Army Air Corps in 1926 as a compromise in the continuing struggle. Although war in Europe prompted Congress to vastly increase the appropriations for the Aviation Section in 1916, it nevertheless tabled a bill proposing an aviation department incorporating all aspects of military aviation. The declaration of war against Germany on April 6, 1917, putting

10143-471: The Posterior Rhine is joined by the Albula , from the east, from the Albula Pass region. The Albula draws its water mainly from the Landwasser with the Dischmabach as the largest source stream, but almost as much from the Gelgia , which comes down from the Julier Pass . Numerous larger and smaller tributary rivers bear the name of the Rhine or equivalent in various Romansh idioms, including Rein or Ragn , including: Next to Reichenau in Tamins
10290-453: The Rhine into Lake Constance forms an inland delta . The delta is delimited in the west by the Alter Rhein and in the east by the modern canalized section of the Alpine Rhine ( Fußacher Durchstich ). Most of the delta is a nature reserve and bird sanctuary . It includes the Austrian towns of Gaißau , Höchst and Fußach . The natural Rhine originally branched into at least two arms and formed small islands by precipitating sediments. In
10437-410: The Services of Supply. A major air depot at Colombey-les-Belles ; three other maintenance depots at Behonne , LaTrecey , and Vinets ; four supply depots at Clichy , Romorantin , Tours , and Is-sur-Tille ; and 12 air park squadrons maintained the combat and training forces. Aircraft acquired from European sources were accepted at Aircraft Acceptance Park No. 1 at Orly , while those shipped from
10584-524: The Signal Corps returned from observing British factory and field methods in aviation operations, just as the Bureau of Aircraft Production concluded that the French were unable to meet their aircraft production goals. Waldon recommended that the regiments be reorganized for aircraft instead of automobile mechanics. The change came too late to affect the 1st and 2nd Regiments, which landed in France in March 1918, but both

Aviation Officer, AEF Chiefs of Air Service, AEF "Though the casualties in the air force were small compared with the total strength, the casualty rate of the flying personnel at the front was somewhat above the Artillery and Infantry rates... The results of allied and American experience at
10878-502: The United States and were assigned to newly created squadrons or as instructors. 1,609 more were commissioned in Europe, with their commissions backdated in February and March 1918 to those of their peers trained in the United States. Pilots in Europe completed an advanced phase in which they received specialized training in pursuit, bombing, or observation at Air Service schools acquired from
11025-404: The United States for assembly in France were delivered to Air Service Production Center No. 2, built on the site of a former pine forest at Romorantin. Ferry operations of over 6,300 new aircraft to the air depots in "often...far from perfect" weather conditions resulted in the successful delivery of 95% and the loss of only eight pilots. A large training establishment was also set up. In France
11172-737: The United States in World War I , came too quickly (less than eight months after its use in Mexico chasing Pancho Villa ) to solve emerging engineering and production problems. The reorganization of the Aviation Section had been inadequate in resolving problems in training, leaving the United States totally unprepared to fight an air war in Europe. The Aviation Section consisted of 131 officers, 1087 enlisted men, and approximately 280 airplanes. The administration of President Woodrow Wilson created an advisory Aircraft Production Board in May 1917, consisting of members of
11319-573: The United States. Personnel were subsequently assigned to the Commanding General, Services of Supply and ordered to report to a staging camp in France. There, personnel awaited scheduling to report to one of the Base Ports in France for transport to the United States and subsequent demobilization. The men of the III Corps Observation Group arrived in New York Harbor in mid July 1919. There most of
11466-827: The advance corps in the Third Army's march to the Rhine River and the Occupation of the Rhineland . The Group was re-organized, being relieved from First Army and transferred to the Third Army Air Service on 21 November 1918. The 88th Squadron which had been active in combat during the Meuse-Argonne Offensive was relieved and transferred to the Third Army VII Corps Observation Group . The 90th
11613-495: The area around the river was made more habitable for humans on flood plains as the rate of flooding decreased sharply. On the French side, the Grand Canal d'Alsace was dug, which carries a significant part of the river water, and all of the traffic. In some places, there are large compensation pools, for example, the huge Bassin de compensation de Plobsheim in Alsace. The Upper Rhine has undergone significant human change since
11760-518: The armistice, the AEF actually received 4,874 aircraft from the French, in addition to 258 from Great Britain, 19 from Italy, and 1,213 of American manufacture, for a total of 6,364 airplanes. 1,664 were classed as training craft. The United States recognized that French skilled labor was severely limited by war casualties, and promised to train and deploy 7,000 automobile mechanics to aid the French Motor Transport Corps. In December 1917
11907-447: The attack due to enemy fire and the engines were constantly overworked. Towards the end of the offensive, the activity and aggressiveness of enemy aviation increased. A squadron with the planes painted red came into the sector on 15 October. This squadron was most aggressive and was said to be Richtofen's "Old Circus". While engaged in combat operations, the Group also operated Infantry liaison schools without interference with work over
12054-525: The attack. In the first phase of the Offensive, in the Argonne-Meuse sector took place at Souilly, beginning the night of 26 October and continuing until 29 October when Headquarters and the squadrons moved to Bethelainville Aerodrome . The Group was well equipped at the beginning of operations with excellent and capable Salmson 2A2 aircraft and outstanding personnel. Many of the planes were damaged during
12201-472: The cadets, the French requested that further movement of cadets be halted because of training backlogs of as much as six months, and no further student pilots were sent to France until they had completed their primary training and been commissioned. During the backlog, more than 1,000 cadets were used as cooks, guards, laborers and other menial jobs, while paid at cadet salary (in the grade and rank of private first class ), for which they became derisively known as
12348-404: The canalized Rhine into the lake. Its water has a darker color than the Rhine; the latter's lighter suspended load comes from higher up the mountains. It is expected that the continuous input of sediment into the lake will silt up the lake. This has already happened to the former Lake Tuggenersee . The cut-off Old Rhine at first formed a swamp landscape. Later an artificial ditch of about two km
12495-481: The centers Basel, Strasbourg and Mannheim-Ludwigshafen. Strasbourg is the seat of the European Parliament , and so one of the three European capitals is located on the Upper Rhine. The Upper Rhine region was changed significantly by a Rhine straightening program in the 19th century. The rate of flow was increased and the ground water level fell significantly. Dead branches were removed by construction workers and
12642-769: The changes proposed along the Rhine, one was "the Treaty for the Rectification of the Rhine flow from Neuberg to Dettenheim"(1817), which surrounded states such as Bourbon France and the Bavarian Palatinate . Loops, oxbows , branches and islands were removed along the Upper Rhine so that there would be uniformity to the river. The engineering of the Rhine was not without protest, farmers and fishermen had grave concerns about valuable fishing areas and farmland being lost. While some areas lost ground, other areas saw swamps and bogs be drained and turned into arable land. Johann Tulla had
12789-462: The colors specified for the U.S. flag, consisting of a white five-pointed star inside of a blue circumscribed circle, with a red circle in the center of the star having a diameter tangent to the pentagon of the interior points of the star. The insignia was ordered painted on both wingtips of the upper surface of the top wing, the lower surface of bottom wings, and the fuselage of all Army aircraft on 17 May 1917. However due to concerns about confusion with
12936-479: The combat units balked at taking orders from Foulois' non-flying staff. Considerable house-cleaning of the existing staff resulted from Patrick's appointment, bringing in experienced staff officers to administrate, and tightening up lines of communication. Pershing had in September 1917 called for creation of 260 U.S. air combat squadrons by December 1918, but slowness of the buildup reduced that on August 17, 1918, to
13083-471: The control systems being used in Europe. Like the rest of the Army, the Aviation Section concluded that training Reserve officers was the solution to its manpower needs and sent a panel of three representatives from each of six U.S. universities to Toronto from 7 to 11 May 1917 to study Canada 's pilot training program. The Chief Signal Officer assigned Major Hiram Bingham III , an adventurer and reserve officer on
13230-514: The creek Aua da Russein (lit.: "Water of the Russein"). In its lower course, the Anterior Rhine flows through a gorge named Ruinaulta (Flims Rockslide). The whole stretch of the Anterior Rhine to the Alpine Rhine confluence next to Reichenau in Tamins is accompanied by a long-distance hiking trail called Senda Sursilvana . The Posterior Rhine flows first east-northeast, then north. It flows through
13377-535: The demobilized First and Second Air services in France. These were the 24th, 168th and 256th. With these additional units, the aerodrome at Weißenthurm was expanded. Also plans were made by Third Army AS to place a main Supply Depot adjacent to the airfield at Weißenthurm. Between 23 and 27 April, the Group participated in the Third Army Horse-Motor and Aviation Show at Coblenz. The 1st Aero Squadron placed
13524-500: The duration of the war plus six months the statutory responsibilities of the Aviation Section and removed the DMA entirely from the Signal Corps (reporting directly to the Secretary of War). The DMA was assigned the function of procuring and training a combat force. In addition, the executive order created a Bureau of Aircraft Production (BAP), a military organization with a civilian director, as
13671-537: The faculty of Yale , to organize a training program on the Canadian model. A three-phase Flying Cadet program came into being, and although systematic, pressing needs for manpower saw many overlaps of the phases. The first phase was an eight-week ground school course conducted by the Schools of Military Aeronautics Division, organized at the six (later eight) American universities, and commanded by Bingham. The first class at
13818-408: The first aerial victory by the U.S. military while flying as a gunner-observer with a French day bombing squadron on February 5, 1918. As other squadrons were organized, they were sent overseas, where they continued their training. The first U.S. squadron to see combat, on February 19, 1918, was the 103rd Aero Squadron , a pursuit unit flying with French forces and composed largely of former members of
13965-549: The first of these being the I Corps Observation Group , organized in April 1918 to patrol the Toul Sector between Flirey and Apremont in support of the U.S. 26th Division . On May 5, 1918, the 1st Pursuit Group was formed, and by the armistice the AEF had 14 heavier-than-air groups (7 observation, 5 pursuit, and 2 bombardment). Of these 14 groups, only the 1st Pursuit and 1st Day Bombardment Groups had their lineage continued into
14112-547: The flow is diverted off the island of Mainau into Lake Überlingen. Most of the water flows via the Constance hopper into the Rheinrinne ("Rhine Gutter") and Seerhein. Depending on the water level, this flow of the Rhine water is clearly visible along the entire length of the lake. The Rhine carries very large amounts of debris into the lake – over three million cubic meters (110,000,000 cu ft) annually. In
14259-527: The formation of six permanent groups in 1919, four of which were based in the United States and two overseas. The first of the new groups, the Army Surveillance Group, was organized in July to direct the operations of three squadrons patrolling the border with Mexico, where revolution had broken out, from Brownsville, Texas to Nogales, Arizona . In addition, the 1st Day Bombardment Group was formed to control four bombardment squadrons at Kelly, while
14406-497: The front indicate that two aviators lose their lives in accidents for each aviator killed in battle." — Report of the Secretary of War, 1919 The Air Service, American Expeditionary Force, totaled 78,507 personnel (7,738 officers and 70,769 enlisted men) at the armistice. Of this total, 58,090 served in France; 20,075 in England; and 342 in Italy. Balloon troops made up approximately 17,000 of
14553-702: The front, while by November 11, 1918, 45 squadrons (20 pursuit, 18 observation, and 7 bombardment ) had been assembled for combat. During the war, these squadrons played important roles in the Battle of Château-Thierry , the St-Mihiel Offensive , and the Meuse-Argonne. Several units, including the 94th Pursuit Squadron under the command of Capt. Eddie Rickenbacker , and the 27th Pursuit Squadron , which had "balloon buster" 1st Lt. Frank Luke as one of its pilots, achieved distinguished records in combat and remained
14700-416: The goal of shortening and straightening the Upper Rhine. Early engineering projects the Upper Rhine also had issues, with Tulla's project at one part of the river creating rapids, after the Rhine cut down from erosion to sheer rock. Engineering along the Rhine eased flooding and made transportation along the river less cumbersome. These state projects were part of the advanced and technical progress going on in
14847-485: The ground schools began 21 May 1917 and concluded 14 July 1917, graduating 147 cadets and enrolling another 1,430. By mid-November, 3,140 had graduated and more than 500 had become rated officers . Out of more than 40,000 applicants, 22,689 were accepted and 17,540 completed ground school training. Approximately 15,000 advanced to primary (preliminary) flying training, a six-to-eight week course conducted by both military and civilian flying instructors, using variants of
14994-1038: The infantry divisions who volunteered to fill a critical shortage in 1918. After the Armistice, the schools graduated 675 additional pilots and 357 observers to serve with the Third Army Air Service in the Army of Occupation . The 3rd Aviation Instruction Center at Issoudun provided 766 pursuit pilots. 169 students and 49 instructors died in training accidents. Balloon candidates made 4,224 practice ascensions while training. Air Service combat losses were 289 airplanes and 48 balloons with 235 airmen killed in action, 130 wounded, 145 captured, and 654 Air Service members of all ranks dead of illness or accidents. Air Service personnel were awarded 611 decorations in combat, including 4 Medals of Honor and 312 Distinguished Service Crosses (54 were oak leaf clusters ). 210 decorations were awarded to aviators by France, 22 by Great Britain, and 69 by other nations. Executive Order 3066, issued by President Wilson on March 19, 1919, formally consolidated
15141-519: The lake level to be lowered by about 10 meters. Previously, the two lakes formed a single lake, as the name still suggests. Like in the Obersee, the flow the Rhine can be traced in the Untersee. Here, too, the river water is hardly mixed with the lake water. The northern parts of the Untersee (Lake Zell and Gnadensee) remain virtually unaffected by the flow. The river traverses the southern, which, in isolation,
15288-410: The lines while at Souilly. Two infantry different detachments of 500 men, with about 50 non-commissioned officers and thirty-two commissioned officers came to the airfield, and were given a 5-day course in work with airplanes. The III Corps Observation Group continued operations at Bethelainville until 11 November, at which time hostilities were suspended The Group had 53 days of combat operations, with
15435-482: The local Alemannic dialect, the singular is pronounced "Isel" and this is also the local pronunciation of Esel (" Donkey "). Many local fields have an official name containing this element. A regulation of the Rhine was called for, with an upper canal near Diepoldsau and a lower canal at Fußach, in order to counteract the constant flooding and strong sedimentation in the western Rhine Delta. The Dornbirner Ach had to be diverted, too, and it now flows parallel to
15582-663: The mail service on May 15. It later extended the route to Boston and added Curtiss R-4LMs to its small fleet, carrying mail until August 12, 1918, when the U.S. Post Office took over. Sent to Europe in March 1917 as an observer, Lieutenant Colonel Billy Mitchell arrived in Paris just four days after the United States declared war and established an office for the American "air service." Upon his arrival in France in June 1917, American Expeditionary Force commanding general John J. Pershing met with Mitchell, who advised Pershing that his office
15729-638: The major European rivers . The river begins in the Swiss canton of Graubünden in the southeastern Swiss Alps . It forms the Swiss-Liechtenstein border and partly the Swiss-Austrian and Swiss-German borders. After that the Rhine defines much of the Franco-German border , after which it flows in a mostly northerly direction through the German Rhineland . Finally in Germany, the Rhine turns into
15876-622: The markings of enemy aircraft , in early 1918 a red, blue, and white roundel similar to those used by the Allied Powers, in the former color arrangement of the defunct Imperial Russian Air Service , was instead ordered painted on all U.S. aircraft operating in Europe, remaining in effect until 1919. On May 6, 1918 Foulois established a policy authorizing creation of emblems for aviation units, and ordered all squadrons to create an official insignia to be painted on each side of an airplane fuselage: "The squadron will design their own insignia during
16023-711: The men were demobilized and returned to civilian life. ** Intermediate locations of Group headquarters while in transit from France to Germany were: Dun-sur-Meuse (11–17 November); Longuyon (18–19 November) and Longwy (20 November) in France; Mamer (21 November); Junglinster (22–30 November), and Echternach (1–2 December) in Luxembourg ; Kyllburg (3–6 December); Daun (7–9 December); Polch (10–14 December), and Neuwied (15–21 December) in Germany.

16170-626: The more precise American manufacturing methods. At the same time the Aeronautical Division of the OCSO was renamed the Air Division with continued responsibility for training and operations but with no influence on acquisition or doctrine. In the end the decision-making process in aircraft procurement was badly fragmented and production on a large scale proved impossible. The Aircraft Board came under severe criticism for failure to meet goals or its own claims of aircraft production, followed by
16317-444: The mouth region, it is therefore necessary to permanently remove gravel by dredging. The large sediment loads are partly due to the extensive land improvements upstream. Three countries border the Obersee, namely Switzerland in the south, Austria in the southeast and the German states of Bavaria in the northeast and Baden-Württemberg in the north and northwest. The Seerhein is only 4 kilometers (2.5 mi) long. It connects
16464-514: The necessity of forming an "air force" to centralize control over tactical aviation. In the St-Mihiel Offensive, commencing September 12, 1918, the American and French offensive against the German salient was supported by 1,481 airplanes directed by Mitchell, totaling 24 Air Service, 58 French Aéronautique Militaire , and three Royal Air Force squadrons in coordinated operations. Observation and pursuit planes supported ground forces, while
16611-611: The north bank and Switzerland on the south, except both sides are Swiss in Stein am Rhein , where the High Rhine flows out of the lake. The High Rhine ( Hochrhein ) begins in Stein am Rhein at the western end of the Untersee. Now flowing generally westwards, it passes over the Rhine Falls ( Rheinfall ) below Schaffhausen before being joined – near Koblenz in the canton of Aargau – by its major tributary,

The Alpine Rhine begins in the westernmost part of the Swiss canton of Graubünden , and later forms the border between Switzerland to the west and Liechtenstein and later Austria to the east. As an effect of human work, it empties into Lake Constance on Austrian territory and not on the border that follows its old natural river bed called Alter Rhein ( lit. ' Old Rhine ' ). The mouth of
16905-534: The other hand, in the east and north. A curiosity of this border line is that the parts of the city of Mainz on the right bank of the Rhine were given to Hesse by the occupying forces in 1945. The Upper Rhine was a significant cultural landscape in Central Europe already in antiquity and during the Middle Ages . Today, the Upper Rhine area hosts many important manufacturing and service industries, particularly in
17052-670: The other two-thirds of the aerial force bombed and strafed behind enemy lines. Later, during the Meuse-Argonne offensive , Mitchell employed a smaller concentration of airpower, nearly all American this time, to keep the German army on the defensive. Promptly after the armistice, the AEF formed the Third United States Army to march immediately into Germany, occupy the Coblenz area, and be prepared to resume combat if peace treaty negotiations failed. Three corps were formed from eight of
17199-513: The passage of the National Defense Act, June 4, 1920 (Public Law 66-242, 41 Stat . 759-88), the Air Service was statutorily recognized as a combatant arm of the line along with the Infantry , Cavalry , Field Artillery , Coast Artillery , Corps of Engineers , and Signal Corps , and given a permanent organization with a fixed complement of personnel. However this also legislated the form of
17346-512: The period of organizational training. The design must be submitted to the Chief of Air Service, AEF, for approval. The design should be simple enough to be recognizable from a distance." The first U.S. aviation squadron to reach France was the 1st Aero Squadron , which sailed from New York in August 1917 and arrived at Le Havre on September 3. A member of the squadron, Lt. Stephen W. Thompson , achieved
17493-509: The post-war Air Service was marked by a prolonged debate between adherents of airpower and the supporters of the traditional military services about the value of an independent Air Force. Airmen such as Brig. Gen. Billy Mitchell supported the independent air concept. The Army's senior leadership from World War I , the United States Navy , and the majority of the nation's political leadership favored integration of all military aviation into
17640-431: The post-war Air Service. In July 1918 the AEF organized its first wing formation, the 1st Pursuit Wing, made up of the 2d Pursuit, 3rd Pursuit, and 1st Day Bombardment Groups. Each army and corps echelon of the ground forces had a chief of air service designated to direct operations. The Air Service, First Army was activated August 26, 1918, marking the commencement of large scale coordinated U.S. air operations. Foulois
17787-512: The river. Some adjacent towns are named after it, such as Rheinau , Rheineck , Rheinfelden (CH) and Rheinfelden (D). The International Commission for the Hydrology of the Rhine Basin (CHR) and EUWID contend that the river could experience a massive decrease in volume, or even dry up completely in case of drought, within the next 30 to 80 years, as a result of the climate crisis . The Rhine
17934-454: The signing of the Treaty of Versailles on June 28, 1919, President Wilson relinquished his war powers under the Overman Act, and on July 11 Congress granted legislative authority to continue the Air Service as a temporary independent branch of the War Department for another year, easing fears of airmen that the Air Service would be demobilized out of existence. At the end of November 1918,
18081-649: The south to the Flüela Pass in the east. The Rhine is one of four major rivers taking their source in the Gotthard region, along with the Ticino (drainage basin of the Po ), Rhône and Reuss (Rhine basin). The Witenwasserenstock is the triple watershed between the Rhine, Rhône and Po. Traditionally, Lake Toma near the Oberalp Pass in the Gotthard region is seen as the source of
18228-497: The squadron was tasked to work with divisional artillery through squadron liaison officers. During the Meuse-Argonne Offensive, the Group Headquarters worked night and day directing the operations, coordinating the work, and suggesting and sending out missions carried out by the squadrons, which returned with valuable and complete information. The progress of the attack was followed the line taken at intervals during each day of
18375-402: The study of photographs, lectures on the cooperation of aviation with the other branches of the Army. Practice flights included long-distance cross country, photographic missions, formation flying and also, the flying of German aircraft obtained and evaluation of their capabilities and other aspects of their construction. On 15 April 1919, four additional squadrons were assigned to the Group from
18522-412: The surface and at first does not mix with the warmer, green waters of Upper Lake. But then, at the so-called Rheinbrech , the Rhine water abruptly falls into the depths because of the greater density of cold water. The flow reappears on the surface at the northern (German) shore of the lake, off the island of Lindau . The water then follows the northern shore until Hagnau am Bodensee . A small fraction of

Its sources are located in the Adula Alps ( Rheinwaldhorn , Rheinquellhorn , and Güferhorn ). The Avers Rhine joins from the south. One of its headwaters, the Reno di Lei (stowed in the Lago di Lei ), is partially located in Italy. Near Sils
18816-533: The time or infrastructure in the United States to equip units to send overseas using aircraft designed and built in the U.S., the AEF Air Service acquired Allied aircraft designs already in service with the French and British air services. On August 30, 1917, the American and French governments agreed to a contract for the purchase of 1,500 Breguet 14 B.2 bombers-reconnaissance planes; 2,000 SPAD XIII and 1,500 Nieuport 28 pursuits for delivery by July 1, 1918. By
18963-720: The units at the front on November 11, 1918, were approximately 11% of the total combat aircraft strength of the Allied forces. The 45 squadrons in the Zone of Advance had 767 pilots, 481 observers, and 23 aerial gunners, covering 137 kilometers of front from Pont-à-Mousson to Sedan . They flew more than 35,000 hours over the front lines. The Air Service conducted 150 bombing missions, the longest 160 miles behind German lines, and dropped 138 tons (125 kg) of bombs. Its squadrons had confirmed destruction of 756 German aircraft and 76 German balloons, creating 71 Air Service aces . Rickenbacker finished

One source is Lai da Tuma (2,345 m (7,694 ft)) with the Rein da Tuma , which is usually indicated as source of the Rhine, flowing through it. Into it flow tributaries from the south, some longer, some equal in length, such as the Rein da Medel , the Rein da Maighels , and the Rein da Curnera . The Cadlimo Valley in
19257-496: The war as the leading American ace, with 26 aircraft destroyed. 35 balloon companies also deployed in France, 17 at the front and six en route to the Second Army, and made 1,642 combat ascensions totaling 3,111 hours of observation. 13 photographic sections were assigned to observation squadrons and made 18,000 aerial photographs. 43 flying training, air park (supply), depot (maintenance), and construction squadrons were located in
19404-412: Was activated on October 12 with Col. Frank P. Lahm as chief but was not ready for operations until just before the armistice. The Air Service, Third Army was created immediately after the armistice to provide aviation support to the army of occupation, primarily from veteran units transferred from the First Army Air Service. Despite their fractious relationship, Mitchell and Foulois were of one mind on
19551-999: Was adapted in Roman-era geography (1st century BC) as Latin Rhenus , and as Greek Ῥῆνος ( Rhēnos ). The spelling with Rh- in English Rhine as well as in German Rhein and French Rhin is due to the influence of Greek orthography, while the vocalization -i- is due to the Proto-Germanic adoption of the Gaulish name as * Rīnaz , via Old Frankish giving Old English Rín , Old High German Rīn , early Middle Dutch ( c. 1200 ) Rijn (then also spelled Ryn or Rin ). The modern German diphthong Rhein (also used in Romansh ) Rein, Rain
19698-453: Was appointed to the vacancy on January 2, 1919, but the patchwork nature of laws and executive orders that had created the various parts of the Air Service prevented him from exercising all their legal powers and ending the unity of command problems caused by dual authority. The United States began the World War with 65 pilots, a few of which were veterans of the Mexican Expedition , and some who were still in training. None were familiar with
19845-448: Was appointed to the vacant position of Second Assistant Secretary of War and designated as Director of Air Service, nominally in charge of the DMA. The Department of Justice report followed two months later and also blamed the delays on administrative and organizational deficiencies in the Aviation Section. Ryan's appointment came too late for any effective consolidation of both agencies, continuing an obstructive division of authority that
19992-417: Was dug. It was made navigable to the Swiss town of Rheineck . Lake Constance consists of three bodies of water: the Obersee ("upper lake"), the Untersee ("lower lake"), and a connecting stretch of the Rhine, called the Seerhein ("Lake Rhine"). The lake is situated in Germany, Switzerland and Austria near the Alps. Specifically, its shorelines lie in the German states of Bavaria and Baden-Württemberg ,
20139-406: Was formed after the St. Mihiel Offensive and for the purpose of operations in the forthcoming Meuse-Argonne Offensive . Its units consisted of a Headquarters Squadron, the 90th Aero Squadron , the 88th Aero Squadron , the Aéronautique Militaire N.284 Escadrille, the N.205 Escadrille, Detachment 10/13/18, and the 199th Park Squadron for logistics and transportation support. The first efforts of
