91-616: The Ludendorff Bridge (sometimes referred to as the Bridge at Remagen ) was a bridge across the river Rhine in Germany which was captured by United States Army forces in early March 1945 during the Battle of Remagen , in the closing weeks of World War II , when it was one of the few remaining bridges in the region and therefore a critical strategic point. Built during World War I to help deliver reinforcements and supplies to German troops on

182-716: A Wonderful Life , during the World War II montage, the narrator, Joseph, says of the character Marty Hatch, "Marty helped capture the Remagen Bridge." The bridge is featured in the 1996 DOS WWII strategy game Offensive . In the Allied campaign, it needs to be captured intact; in the Axis campaign, it needs to be destroyed to slow the Allied advance. The final three missions in the 2004 PS2 game Call of Duty: Finest Hour ("Road to Remagen", "Last Bridge Standing" and "Into

273-474: A central arch span of 156 metres (512 ft). It had dual tracks that could be covered with planks to allow vehicular traffic. The steel section was 325 metres (1,066 ft) long, and it had an overall length of 398 metres (1,306 ft). On the eastern bank the railway passed through Erpeler Ley, a steeply rising hill over 150 metres (490 ft) high. The tunnel was 383 metres (1,257 ft) long. The arch at its highest measured 28.5 metres (94 ft) above

364-462: A combat engineer who has graduated from various levels of combat engineering training. Sapper 05 is the basic level, Sapper 06 is the general level, Sapper 08 is the combat engineer commander's level, and Sapper 11 is the combat engineer officer level. All IDF sappers are also trained as Rifleman 07, matching infantry . In the Canadian Army , it is a term for soldiers that have completed

455-529: A control panel inside the rail tunnel under Erpeler Ley, where engineers could safely detonate the charges. As a backup, engineers laid primer cord that could be manually ignited. They believed they could destroy the bridge when necessary with minimal preparation. On 14–15 October 1944, an American bomb had struck a chamber containing the demolition charges of the Mulheim Bridge in Cologne, destroying

546-413: A domestication that served goals such as reducing stagnant bogs that fostered waterborne diseases, making regions more habitable for human settlement, and reduce high frequency of floods. 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

637-471: A key role in all armed forces of the world. They are invariably found closely integrated into the force structure of divisions, combat brigades, and smaller fighting units. In many countries, combat engineers provide combat support members of a broader military engineering corps or branch. Other nations have distinct combat engineering corps or branches; they are separate from other types of military engineers. The Danish military engineers' corps, for example,

728-403: A museum and the towers on the east bank are now a performing-arts space. A 2020 poll of local people found that 91% favoured rebuilding the bridge; without it there is no river crossing for 44 km (27 mi), and few ferries. In 2022 plans were initiated to build a suspension bridge for pedestrians and cyclists. Local communities indicated an interest to help fund the project and an engineer

819-717: A pedestrian catwalk on either side. Work on the bridge pillars and arches was done by leading construction companies Grün & Bilfinger with the steel bridge built by MAN-Werk Gustavsburg . It was one of three bridges built to improve railroad traffic between Germany and France during World War I; the others were the Hindenburg Bridge at Bingen am Rhein and the Urmitz Bridge on the Neuwied–Koblenz railway near Koblenz . The railway bridge had three spans, two on either side 85 metres (279 ft) long and

910-487: A sapper is a soldier who has specialized combat engineer training. The term "sapper" in the U.S. Army refers to a person who either possesses the combat engineer military occupational specialty or who has graduated from the Sapper Leader Course, more commonly called "Sapper School." In Sapper School, volunteers from the ranks of combat engineers and other military occupational specialties (most of whom serve in

1001-747: Is a Central German development of the early modern period , with the Alemannic name R(n) keeping the older vocalism. 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

1092-495: Is a term used (or formerly used) in many Commonwealth armies. In modern usage, it is often synonymous with combat engineer. However, the term originally identified those military engineers who supported an army operating in the field instead of garrison engineers who built and supported permanent fixed bases. In its original usage, "field engineering" would have been inclusive of but broader than "combat engineering." Sappers specialising in tunnel warfare may be known as miners. In

1183-403: Is a type of soldier who performs military engineering tasks in support of land forces combat operations. Combat engineers perform a variety of military engineering, tunnel and mine warfare tasks, as well as construction and demolition duties in and out of combat zones. Combat engineers facilitate the mobility of friendly forces while impeding that of the enemy. They also work to assure

1274-541: Is almost entirely organized into one regiment of combat engineers, simply named Ingeniørregimentet ("The Engineering Regiment"). Combat engineer battalions are usually a part of a brigade combat team . During the War in Afghanistan and the 2003–2011 Iraq War , the U.S. Army tasked its combat engineers with route clearance missions designed to counter rising threats of improvised explosive devices (IEDs). To increase

1365-549: Is another area of military engineering but is often performed by the combat engineers of some nations and in other cases is a separate responsibility, as was formerly the case in the Australian Army. While the officers of a combat engineer unit may be professionally certified civil or mechanical engineers, the non-commissioned members are generally not. In the British, Indian, Canadian, Australian, and New Zealand armies,

1456-589: 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

1547-469: Is often called a pioneer or sapper , terms derived respectively from the French and British armies. In some armies, pioneer and sapper indicate specific military ranks and levels of combat engineers, who work under fire in all seasons and may be allocated to different corps, as they were in the former Soviet Army, or they may be organized in the same corps. Geomatics (surveying and cartography)

1638-649: Is significantly shortened from its natural course due to a number of canal projects completed in the 19th and 20th century. 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

1729-784: 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

1820-503: Is to slow down the advance of attackers to where they can be destroyed by defenders from sheltered positions. Most large fortifications are not a single structure but rather a concentric series of fortifications of increasing strength. Combat engineers employ a wide range of transportation vehicles and equipment and use weapons unique to the engineers, including those used in land mine warfare. Basic combat engineering tools include safe use of: For obstacle breaching, including minefields,

1911-633: The 19th SFG and 20th SFG of the US Army National Guard , employ combat engineer sergeants designated by MOS 18C. A Green Berets Operational Detachment Alpha , more commonly known as an "A-Team", typically consists of 12 men, two of whom are combat engineer sergeants. Another example is the Israeli Yahalom unit, which is a special operations engineering unit, that possess the abilities of sabotage, demolition of explosives and tunnel warfare . A general combat engineer

2002-526: 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,

2093-665: The Anterior Rhine and the Posterior Rhine join and form the Alpine Rhine. The river makes a distinctive turn to the north near Chur . 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

2184-581: The French Army , combat engineers specialising in bridge-building are called pontoniers , while in the Italian Army , combat engineers specialising in bridge-building are called pontieri . Combat engineers are force multipliers and enhance the survival of other troops through the use and practice of camouflage, reconnaissance, communications and other services. These include the construction of roads, bridges, field fortifications , obstacles and

2275-815: The Neckar in Mannheim and the Main across from Mainz. In Mainz, the Rhine leaves the Upper Rhine Valley and flows through the Mainz Basin. The southern half of the Upper Rhine forms the border between France ( Alsace ) and Germany (Baden-Württemberg). The northern part forms the border between the German states of Rhineland-Palatinate in the west on the one hand, and Baden-Württemberg and Hesse on

2366-670: 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 the river. Some adjacent towns are named after it, such as Rheinau , Rheineck , Rheinfelden (CH) and Rheinfelden (D). The International Commission for

2457-509: The Obersee with the 30 cm lower Untersee . Distance markers along the Rhine measure the distance from the bridge in the old city center of Konstanz. 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

2548-701: The Rhine knee , a major bend, where the overall direction of the Rhine changes from west to north. Here the High Rhine ends. 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,

2639-400: The Rhine knee , the river turns north and leaves Switzerland altogether. The High Rhine is characterized by numerous dams. 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

2730-484: The Western Front , it connected Remagen on the west bank and the village of Erpel on the east bank between two hills flanking the river. Midway through Operation Lumberjack , on 7 March 1945, the troops of the 1st U.S. Army approached Remagen and were surprised to find that the bridge was still standing. Its capture, two weeks before Field Marshal Bernard Montgomery 's planned Operation Plunder , enabled

2821-750: 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

Some of the training in this 28-day course, arguably one of the most challenging in the U.S. Army, features covert infiltration techniques or survival skills. In the Israeli Defense Forces , sapper (פלס) is a military profession code denoting

3003-680: The confluence of the Rein Anteriur/Vorderrhein and Rein Posteriur/Hinterrhein next to Reichenau in Tamins . Above this point is the extensive catchment area of the headwaters of the Rhine. This area belongs almost exclusively to the Swiss canton of Grisons ( Graubünden ), ranging from Saint-Gotthard Massif in the west via one valley lying in the canton of Ticino and Sondrio ( Lombardy , Italy) in

3094-493: The 17th and 18th centuries. The Rhine near Remagen is about 300 m (980 ft) wide. During Operation Lumberjack , on 7 March 1945, troops of the U.S. Army 's 9th Armored Division reached the bridge during the closing weeks of World War II and were surprised to see that the railroad bridge was still standing. It was one of very few bridges remaining across the Rhine, because the Germans had systematically destroyed all of

3185-516: The 19th century. 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,

3276-614: 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

3367-521: The Austrian state of Vorarlberg , and the Swiss cantons of Thurgau and St. Gallen . The Rhine flows into it from the south following the Swiss-Austrian border. It is located at approximately 47°39′N 9°19′E  /  47.650°N 9.317°E  / 47.650; 9.317 . The flow of cold, grey mountain water continues for some distance into the lake. The cold water flows near

3458-643: 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 a waterway in the Holy Roman Empire . Among the largest and most important cities on the Rhine are Cologne , Rotterdam , Düsseldorf , Duisburg , Strasbourg , Arnhem , and Basel . The variants of

The final mission in the 2017 video game Call of Duty: WWII involves the player in helping take the bridge. The Bridge at Remagen is a 1969 DeLuxe Color war film in Panavision starring George Segal , Ben Gazzara and Robert Vaughn . The film is a highly fictionalized version of actual events during

3640-480: The High Rhine forms the border between Germany and Switzerland . Only for brief distances at its extremities does the river run entirely within Switzerland; at the eastern end it separates the bulk of the canton of Schaffhausen and the German exclave of Büsingen am Hochrhein on the northern bank from cantons of Zürich and Thurgau , while at the western end it bisects the canton of Basel-Stadt . Here, at

3822-663: The Latin Ren- . The Gaulish name Rēnos ( Proto-Celtic or pre-Celtic *Reinos ) belongs to a class of river names built from the PIE root *rei- "to move, flow, run", also found in other names such as the Reno in Italy. The grammatical gender of the Celtic name (as well as of its Greek and Latin adaptation) is masculine, and the name remains masculine in German, Dutch, French, Spanish and Italian. The Old English river name

3913-875: 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

4004-453: 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

4095-413: The Rhine. The bridge, while it stood, and newly established pontoon bridges , enabled the U.S. Army to secure a bridgehead of six divisions , about 125,000 troops, with accompanying tanks, artillery pieces, and trucks, across the Rhine. Capturing the bridge hastened the war's conclusion, and V-E Day came on May 8. After the war, the bridge was not rebuilt; the towers on the west bank were converted into

4186-411: The U.S. Army to establish a bridgehead on the eastern side of the Rhine. After the U.S. forces captured the bridge, German forces tried to destroy it many times. It finally collapsed on 17 March 1945, 10 days after it was captured; 28 Army engineers were killed in the collapse while a further 63 were injured. Of those who died, 18 were actually missing, but presumably had drowned in the swift current of

4277-411: The U.S. forces to envelop the German industrial area of the Ruhr . Six Allied divisions crossed the damaged bridge, then it was closed for repairs, and a pontoon bridge that had been built across the river was used. The Germans sent several bombing missions to destroy the Remagen bridge; it collapsed due to cumulative damage from the unsuccessful detonation and the bombs on 17 March 1945, 10 days after it

4368-503: The ability of one's own force to move around the battlefield. Combat engineers typically support this role through reduction of enemy obstacles which include point and row minefields, anti-tank ditches, wire obstacles, concrete, and metal anti-vehicle barriers, and improvised explosive devices (IED) and wall and door breaching in urban terrain. Mechanized combat engineer units also have armored vehicles capable of laying short bridges for limited gap-crossing. Building obstacles to prevent

4459-442: 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

4550-482: The attackers. The placement of land mines to create minefields and their maintenance and removal. Building structures which enable one's own soldiers to survive on the battlefield. Examples include trenches, bunkers, shelters, and armored vehicle fighting positions. Defensive fortifications are designed to prevent intrusion into the inner works by infantry . For minor defensive locations, these may only consist of simple walls and ditches. The design principle

4641-418: The basic Combat Engineer training. In the Portuguese Army , a sapador de engenharia (engineering sapper) is a soldier of the engineering branch that has specialized combat engineer training. A sapador de infantaria (infantry sapper) is a soldier of the infantry branch that has a similar training and that usually serves in the combat support sapper platoon of an infantry battalion. The Italian Army uses

4732-427: The bridge. German leader Adolf Hitler reacted by demanding that demolition charges on bridges could only be set when the enemy was within a specific distance, and only exploded by written order. He ordered those "responsible" for the destruction of the Mulheim Bridge court-martialed . This left officers responsible for destroying bridges, in the event that the enemy approached, nervous about both blowing it too soon and

4823-404: 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

4914-420: 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

5005-603: 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

5096-407: The combat engineers in the Austro-Hungarian k.u.k. Forces were called "Pioniere". In the British, Canadian, Australian and New Zealand armies, an assault pioneer is an infantry soldier with some limited combat engineer training in clearing obstacles during assaults and light engineering duties. Until recently, assault pioneers were responsible for the operation of flamethrowers . Field engineer

5187-415: The consequences if they failed. In keeping with Hitler's orders, by 7 March 1945, the charges on the Ludendorff Bridge had been removed and were stored nearby. In March 1945, about 5,100 people lived in Remagen. On the western shore, the Allied bombing campaign had destroyed more than half of Erpel's buildings, including all the buildings between Erpel's marketplace and the bridge, which had been built during

5278-774: The construction and running of water points. In these roles, combat engineers use a wide variety of hand and power tools. They are also responsible for construction rigging, the use of explosives , and the carrying out of demolitions, obstacle clearance, and obstacle construction, assault of fortifications, use of assault boats in water obstacle crossings, helipad construction, general construction, route reconnaissance and road reconnaissance, and erecting communication installations. Combat engineers build and run water distribution points, carrying out water filtration, and NBC decontamination when necessary, and storage prior to distribution. All these role activities and technologies are divided into several areas of combat engineering: Improving

5369-412: The country alongside the industrial revolution. For the German state, making the river more predictable was to ensure development projects could easily commence. The section of the Upper Rhine downstream from Mainz is also known as the "Island Rhine". Here a number of river islands occur, locally known as "Rheinauen". Combat engineer A combat engineer (also called pioneer or sapper )

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

5551-465: The effectiveness of these units, EOD and mechanic teams were typically embedded with the combat engineer platoon. Due to rising IED threats, the U.S. Army sends some combat engineers to complete Explosive Ordnance Clearance Agent training. Individual combat engineers are often assigned as a component of both covert and overt direct action special operations teams. For example, the active duty US Army Special Forces and its two reserve components ,

Destroying bridges, blocking roads, creating airstrips, digging trenches, etc. Can also include planting land mines and anti-handling devices when authorized and directed to do so. When the defender must retreat it is often desirable to destroy anything that may be of use to the enemy, particularly bridges, as their destruction can slow the advance of

5733-447: The flat roof of the towers troops had a good view of the valley. To protect the bridge, both an engineering unit and a military police unit were assigned to the site. The designers built cavities into the concrete piers where demolition charges could be placed. During the Occupation of the Rhineland after World War I, the French filled these cavities with concrete. It was one of the four bridges that were guarded by Americans during

5824-444: 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

5915-416: 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

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,

The World War II game Hell Let Loose features Ludendorff Bridge in the "Remagen" map where players fight for control of the bridge. Rhine The Rhine ( / r aɪ n / RYNE ) is one of the major European rivers . The river begins in the Swiss canton of Graubünden in

6188-482: 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

6279-406: The middle of 2018, the two eastern towers of the bridge were announced to be for sale. Three bids were submitted, but due to the poor condition of the building and expected costs of approximately €1.4 million for its restoration, the sale was expected to be difficult. Plans were announced to rebuild a pedestrian and cycle bridge on the site of the original railway bridge in 2022. In the film It's

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

6461-426: The name of the Rhine (Latin Rhenus; French Rhin, Italian Reno, Romansh Rain or Rein, Dutch Rijn, Alemannic Ry, Ripuarian Rhing) in modern languages are all derived from the Gaulish name Rēnos , which 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

6552-683: 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,

6643-535: The occupation. In 1938, after the Germans reacquired the Rhineland and control of the bridge, they attached 60 zinc-lined boxes at key structural points to the bridge girders, each capable of containing 3.66 kg (8.1 lb) of explosives. The system was designed to detonate all 60 charges at once. The engineers connected the charges in the piers and the zinc boxes by electrical cable protected by steel pipe to

6734-506: The open Sztal valley and then through Lake Walen and Lake Zurich into the Aare . 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

6825-551: The order was not carried out due to opposition from German generals and the rapid Allied advance. Instead, U.S. forces advanced rapidly through Germany, and by 12 April the Ninth United States Army had crossed the Elbe . After the war, the railway crossing was not deemed important enough to justify rebuilding the bridge. Parts of the land used for the approaching railway lines are now used as an industrial estate on

6916-547: 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

7007-480: The others in advance of the Allies' attack. Although the bridge was wired with demolition charges, the weak civilian-grade "Donarite" explosives damaged the bridge but failed to bring it down, and Allied engineers risked their lives manually removing the remaining charges before the bridge was captured. The ability to quickly establish a bridgehead on the eastern side of the Rhine and to get forces into Germany allowed

7098-673: 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

7189-744: 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 a predominantly westerly direction and flows into the Netherlands where it eventually empties into

7280-412: 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

7371-688: The survivability of friendly forces, building fighting positions, fortifications , and roads . They conduct demolition missions and clear minefields manually or through use of specialized vehicles . Common combat engineer missions include construction and breaching of trenches, tank traps and other obstacles and fortifications ; obstacle emplacement and bunker construction; route clearance and reconnaissance; bridge and road construction or destruction; emplacement and clearance of land mines ; and combined arms breaching. Typically, combat engineers are also trained in infantry tactics and, when required, serve as provisional infantry. Combat engineers play

7462-549: The term guastatori for their combat engineers. In the Finnish army , pioneeri is the private equivalent rank in the army for a soldier who has completed the basic combat engineering training. Naval engineers retain the rank matruusi but bear the pioneeri insignia on their sleeves. The German Bundeswehr uses the term Pionier for their combat engineers and other specialized units, who are associated with Special Forces to clear obstacles and perform engineering duties. Also

7553-567: The three valleys named Rheinwald , Schams and Domleschg - Heinzenberg . The valleys are separated by the Rofla Gorge and Viamala Gorge. 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

7644-499: The upper Surselva and flows in an easterly direction. 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

7735-461: The water. Its main surface was normally about 15 metres (48 ft) above the Rhine. The 4,640-tonne (5,110-short-ton) structure cost about 2.1 million marks when it was built during World War I. Since the bridge was a major military construction project, both abutments of the bridge were flanked by stone towers with fortified foundations that could shelter up to a full battalion of men. The towers were designed with fighting loopholes for troops. From

7826-438: The western bank and a park on the eastern bank. Since 1980, the surviving towers on the western bank of the Rhine have housed a museum called "Peace Museum Bridge at Remagen" containing the bridge's history and 'themes of war and peace'. This museum was partly funded by selling rock from the two piers as paperweights, the two piers having been removed from the river in the summer of 1976 as they were an obstacle to navigation. In

7917-606: Was a key advocate for building this bridge during World War I , and it was named after him. It was designed by Karl Wiener to connect the Right Rhine Railway , the Left Rhine Railway and the Ahr Valley Railway ( Ahrtalbahn ) and carry troops and supplies to the Western Front . Constructed between 1916 and 1919, using Russian prisoners of war as labour, it carried two railway lines and

8008-411: Was captured. The collapse killed 28 and injured 93 U.S. Army Engineers. The unexpected availability of the first major crossing of the Rhine, Germany's last major natural barrier and line of defence, caused Allied high commander Dwight D. Eisenhower to alter his plans to end the war. Hitler's Nero Decree of 19 March ordered the destruction of any infrastructure that could aid the Allied advance, but

8099-570: Was commissioned to draw up plans. Remagen is located close to and south of the city of Bonn . The town of Remagen was founded by the Romans about 2,000 years earlier. It had been destroyed multiple times and rebuilt each time. Under the Schlieffen Plan , a bridge was planned to be built there in 1912, as well as bridges in Engers and Rüdesheim am Rhein . German General Erich Ludendorff

8190-468: 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 ,

8281-465: Was variously inflected as masculine or feminine; and its Old Icelandic adoption was inflected as feminine. The length of the Rhine is conventionally measured in "Rhine-kilometers" ( Rheinkilometer ), a scale introduced in 1939 which runs from the 0 km datum at Old Rhine Bridge in the city of Konstanz , at the western end of Lake Constance , to the Hook of Holland at 1,036.20 km.
