116-623: The Dardanelles Army was formed in late 1915 and comprised the three army corps of the British Army operating at Gallipoli . It was created as a result of the reorganisation of headquarters when the second Mediterranean front opened at Salonika . Prior to this, all British (and Dominion ) units in the Mediterranean came under GHQ of the Mediterranean Expeditionary Force . The Dardanelles Army
232-582: A corps d'armée in 1815 for commanding his mixed allied force of four divisions against Napoleon I. When the British Army was expanded from an expeditionary force in the First World War, corps were created to manage the large numbers of divisions. The British corps in World War I included 23 infantry corps and a few mounted corps. The word was adopted for other special formations such as
348-463: A "war without hate", a pure military clash in the desert without the partisan murders and ethnic cleansing that was occurring across Europe. This view has been challenged by recent historians, given that there were indeed many civilians who lived in the region and the campaign was marked by numerous atrocities and abuses by both Italian and German forces towards Allied prisoners of war and local Jewish , Berber , and Arab populations. After victory by
464-569: A Canadian corps headquarters. This corps was renamed I Canadian Corps as a second corps headquarters was established in the UK, with the eventual formation of five Canadian divisions in England. I Canadian Corps eventually fought in Italy, II Canadian Corps in northwest Europe, and the two were reunited in early 1945. After the formations were disbanded after VE Day, Canada has never subsequently organized
580-457: A MEF headquarters group, a Marine division, a Marine aircraft wing, and a force service support group (re-designated as Marine logistics group in 2005). The pre– World War II Red Army of the former USSR had rifle corps much like in the Western sense with approximately three divisions to a corps. However, after the war started, the recently purged Soviet senior command ( Stavka ) structure
696-518: A communications regiment (or a separate battalion). In 1945, air defence corps could include 1 anti-aircraft artillery brigade or division. Air defence fighters operating within the limits of responsibility of the KPVO was transferred to the corps. By the end of the war, there were 14 KPVO in the Active Army, of which 5 corps continued to carry out the tasks assigned to them even after the war, and
812-477: A corps headquarters. Royal Canadian Army Cadets : A corps size in the RCAC is different everywhere, depending on the size. The commanding officer can be a captain (Previously, Commanding Officers of a large corps could have been a Major, but that capability has been removed with the creation of CJCR Group Order 5511-1) The National Revolutionary Army (NRA) corps ( 軍團 ) was a type of military organization used by
928-407: A corps is also a grouping of personnel by common function, also known as an arm , service , mustering or branch . In the British Army, an administrative corps performs much the same role – for personnel that otherwise lack them – as a ceremonial regiment . An administrative corps therefore has its own cap badge , stable belt , and other insignia and traditions. In some cases, the term corps
1044-500: A dedicated Cavalry Corps of three divisions and horse artillery assigned to the corps headquarters. In the early years of the war, field artillery was either part of an artillery reserve under direct army control or assigned to individual divisions. However, after the Battle of Chancellorsville the divisional artillery was placed under corps control, with each corps assigned a brigade of between four and six batteries commanded by
1160-657: A difficult challenge for the British forces. However, the Allies were left with the advantage of having secured the island of Malta, enabling the Allies to carry out future aerial operations. Additionally, on land, allied British and American forces were able to hold onto their possessions. On December 4, 1942, the Allied Force Headquarters in North Africa reported that military operations were ongoing in
1276-511: A generic term for a non-military organization , such as the US Peace Corps and European Solidarity Corps . In many armies, a corps is a battlefield formation composed of two or more divisions , and typically commanded by a lieutenant general . During World War I and World War II , due to the large scale of combat, multiple corps were combined into armies which then formed into army groups . In Western armies with numbered corps,

#17327825935161392-547: A number of aides-de-camp and a general staff of other officers. This staff consisted of a chief of cavalry, a chief of artillery, and representatives of the War Department 's various bureaus: an assistant adjutant general , a quartermaster , an assistant inspector general , a commissary of subsistence, an ordnance officer (all with the rank of lieutenant colonel ), and a medical director. However, there were no dedicated combat service support formations as part of
1508-509: A number of their documents captured, alerting British intelligence to the problem. The British responded by instituting an improved call signal procedure, introducing radiotelephonic codes, imposing rigid wireless silence on reserve formations, padding out real messages with dummy traffic, tightening up on their radio discipline in combat and creating an entire fake signals network in the southern sector. Allied codebreakers read much enciphered German message traffic, especially that encrypted with
1624-413: A numerically superior foe. This allowed Napoleon I to mass the bulk of his forces to effect a penetration into a weak section of enemy lines without risking his own communications or flank. This innovation stimulated other European powers to adopt similar military structures. The corps has remained an echelon of French Army organization to the modern day. As fixed military formation already in peace-time it
1740-646: A series of raids against Italian positions in Libya. Following the defeat of France on 25 June, Italian forces in Tripolitania – facing French troops based in Tunisia – redeployed to Cyrenaica to reinforce the Italian Tenth Army . This, coupled with the steadily degrading equipment of the British forces, led General Archibald Wavell to order an end to the raids and place the defence of
1856-608: A significant role in informing the Germans of allied strength and intentions between January and June 1942 In addition, the Italian Servizio Informazioni Segrete or SIS code-breakers were able to successfully intercept much radio encrypted signals intelligence (SIGINT) from British aircraft traffic as well as first-class ciphers from British vessels and land bases, providing Supermarina (Regia Marina) with timely warnings of Allied intentions in
1972-420: A small-scale counter-attack called Operation Brevity in an attempt to push Axis forces off the key passes at the border, with some initial success. However they could not hold the advance positions and followed Brevity up with a much larger-scale offensive, Operation Battleaxe intended to relieve the siege at Tobruk, but this operation also failed. Following the failure of Operation Battleaxe, Archibald Wavell
2088-399: A soldier as part of a specific corps (or sometimes individual battalion). This lanyard is a woven piece of cord which is worn on ceremonial uniforms and dates back to the issue of clasp knives in the early 20th century which were secured to the uniform by a length of cord. If a soldier is posted to a unit outside of their parent corps, except in some circumstances the soldier continues to wear
2204-505: Is also used informally, for looser groupings of independent regiments and other units – and without many or any unifying regalia , military traditions or other accoutrements – such as the Royal Armoured Corps or the "Corps of Infantry". In Australia, soldiers belong foremost to a corps which defines a common function or employment across the army. The Australian Army has a system of coloured lanyards, which each identify
2320-480: Is an operational-tactical formation (in the past - the highest tactical formation) of the former Soviet Air Defence Forces and now Russian Air Defence Forces /Aerospace Forces. The purpose of the such a corps is to protect important administrative, industrial and economic centers and regions of the country, groupings of troops (forces) and military facilities within the established limits of responsibility against air strikes. In organizational terms, an air defence corps
2436-500: Is composed of three or four divisions. There are three types of corps in the Indian Army: strike, holding and mixed. The corps HQ is the highest field formation in the army. The Pakistan Army has nine manoeuvre corps, each commanded by a lieutenant general . Each corps is composed of at least two divisions. The corps HQ is the highest field formation in the army. The Polish Armed Forces used independent operational groups in

#17327825935162552-571: Is part of the district (or a separate army) of the Air Defence Forces. Also some air defence corps were separate. On the basis of individual corps, air defence zones or air defence corps areas could be created. The first KPVO were created in February 1938 for the air defence of Moscow , Leningrad and Baku (respectively 1st, 2nd and 3rd) based on anti-aircraft artillery divisions and air defence brigade ( 3rd KPVO ). The staff of
2668-561: Is strongly disputed by the authors Vincent P. O'Hara and Enrico Cernuschi (2013) who claim that historians like F.H. Hinsley have greatly exaggerated the effects of Ultra. For example, they claim that intelligence provided by Ultra had little impact in stopping Italian convoys reaching North Africa. Of the 2.67 million tons of materiel, fuel, and munitions shipped to Africa – nearly all in Italian vessels and under Italian escort – 2.24 million tons managed to arrive despite
2784-489: Is the highest level of the forces that is concerned with actual combat and operational deployment. Higher levels of command are concerned with administration rather than operations, at least under current doctrine. The corps provides operational direction for the forces under its command. As of 2014, the active field corps in the US Army are I Corps , III Corps , and XVIII Airborne Corps ; their lineages derive from three of
2900-599: The Afrika Korps by Adolf Hitler , was placed under the command of Erwin Rommel . His orders were to reinforce the Italians and block Allied attempts to drive them out of the region. However, the initial commitment of only one panzer division and subsequently, no more than two panzer and one motorized divisions, indicated the limited extent of German involvement and commitment to this theatre of operations. The bulk of

As of July 2016, the Army deactivated all corps headquarters save three CONUS based corps ( I Corps - Washington, III Corps - Texas, and XVIII Airborne Corps - North Carolina). In the 1960s, the Marine Corps activated the I Marine Expeditionary Force (I MEF) on Okinawa (based in California since 1971) and II Marine Expeditionary Force (II MEF) in North Carolina, and re-activated
3132-673: The Allied Rapid Reaction Corps in 1994. It is no longer a purely British formation, although the UK is the "framework nation" and provides most of the staff for the headquarters. A purely national Corps headquarters could be quickly reconstituted if necessary. It took command of the International Security Assistance Force in Afghanistan on 4 May 2006. Previously, it was deployed as the headquarters commanding land forces during
3248-847: The Allies and the Axis Powers . It included campaigns in the Libyan and Egyptian deserts ( Western Desert campaign , Desert War), in Morocco and Algeria ( Operation Torch ), and in Tunisia ( Tunisia campaign ). The Allied war effort was dominated by the British Commonwealth and exiles from German-occupied Europe . The United States officially entered the war in December 1941 and began direct military assistance in North Africa on 11 May 1942. Fighting in North Africa started with
3364-834: The British Eighth Army – advancing westward along the North African coast – had reached the Tunisian border. Rommel and von Arnim found themselves in an Allied "two army" pincer. They were outflanked, outmanned and outgunned. Rommel went back to Germany for health reasons and was substituted by the Italian general Messe . The British Eighth Army bypassed the Axis defence on the Mareth Line in late March after harsh fighting and First Army in central Tunisia launched their main offensive in mid-April to squeeze

3712-506: The Enigma machine . The Allies' Ultra programme was initially of limited value, as it took too long to get the information to the commanders in the field, and at times provided information that was less than helpful. In terms of anticipating the next move the Germans would make, reliance on Ultra sometimes backfired. Part of the reason the initial German attacks in March 1941 were so successful
3828-731: The First Australian Imperial Force (AIF)—consisting entirely of personnel who had volunteered for service overseas—were united as the Australian Corps , on the Western Front , under Lieutenant General Sir John Monash . During World War II, the Australian I Corps was formed to co-ordinate three Second Australian Imperial Force (2nd AIF) units: the 6th , 7th and 9th Divisions , as well as other Allied units on some occasions, in

The size of a corps varies greatly, but two to five divisions and anywhere from 40,000 to 80,000 are the numbers stated by the US Department of Defense. Within military terminology a corps may be: These usages often overlap. Corps may also be
4408-635: The Naval Battle of Casablanca , which ended in an American victory. The Allied landings prompted the Axis occupation of Vichy France ( Case Anton ) including an attempt to capture the French fleet at Toulon, which did them little good, as the main portion of the fleet was scuttled to prevent their use by the Axis. The Vichy Army in North Africa joined the Allies. Following the Operation Torch landings – from early November 1942 –

Following the commencement of the Pacific War , there was a phased withdrawal of I Corps to Australia, and the transfer of its headquarters to the Brisbane area, to control Allied army units in Queensland and northern New South Wales (NSW). II Corps was also formed, with Militia units, to defend south-eastern Australia, and III Corps controlled land forces in Western Australia . Sub-corps formations controlled Allied land forces in

4872-558: The Royal Navy at night. Rommel's forces did not have the strength or training to take the fortress. This created a supply problem for his forward units. His front-line positions at Sollum were at the end of an extended supply chain that stretched back to Tripoli and had to bypass the coast road at Tobruk. Further, he was constantly threatened with a breakout of the British forces at Tobruk. Without Tobruk in Axis hands, further advances into Egypt were impractical. The Allies launched

However, in September 1941, the Italians had stolen a code book containing the Black Code, photographed it and returned it to the US embassy in Rome. The Italians shared parts of their intercepts with their German allies. In addition the " Chiffrierabteilung " (German military cipher branch) were soon able to break the code.

The Axis forces drove the Eighth Army back over the Egyptian border, but their advance was stopped in July only 90 miles (140 km) from Alexandria in the First Battle of El Alamein . Of great significance, on 29 June reports of British military operations in North Africa sent to Washington by the US military attaché in Cairo, Bonner Fellers , no longer used

Nearly 400,000 Axis and Allied troops were lost, injured or died of disease by the end of the North African campaign. Sono circa 400.000 i prigionieri fatti dagli inglesi in Etiopia e in Africa settentrionale, 125.000 presi dagli americani in Tunisia e in Sicilia, 40.000 lasciati ai francesi in Tunisia ("There were about 400,000 prisoners taken by

By early December, the Eastern Task Force – which had been redesignated as the British First Army under Lieutenant-General Kenneth Anderson – was composed of the British 78th Infantry Division , British 6th Armoured Division , 1st Parachute Brigade , No. 6 Commando and elements of US 1st Armored Division . But by this time, one German and five Italian divisions had been shipped from Europe and
5568-436: The Allies, the British not only failed to change their codes with any frequency, they were also prone to poor radio discipline in combat. Their officers made frequent open, uncoded transmissions to their commands, allowing the Germans to more easily identify British units and deployments. The situation changed after a counterattack during the Battle of Gazala resulted in the 621st Signals Battalion being overrun and destroyed, and
5684-415: The Anglo-American landings in North-West Africa in November 1942 and fighting against Vichy France forces (which then changed sides), the Allies trapped about 250,000 German and Italian personnel in northern Tunisia, forcing their surrender in May 1943. Information gleaned via British Ultra code-breaking was important in the Allied victory in North Africa. The Italian campaign followed, culminating in
5800-416: The Armistice, the peacetime Canadian militia was nominally organized into corps and divisions but no full-time formations larger than a battalion were ever trained or exercised. Early in the Second World War, Canada's contribution to the British-French forces fighting the Germans was limited to a single division. After the fall of France in June 1940, a second division moved to England, coming under command of

#17327825935166032-447: The Army and Marines diverged in their approach to the concept of the field corps. The Army continued to group its divisions into traditional corps organizations in the Continental United States (CONUS), West Germany ( V Corps and VII Corps ), and South Korea (I Corps). However, during the Vietnam War , the Army designated its corps-level headquarters in South Vietnam as I Field Force and II Field Force to avoid confusion with

The last Axis force to surrender in North Africa was the 1st Italian Army of General Messe. This huge loss of experienced troops greatly reduced the military capacity of the Axis powers, although some Axis troops escaped Tunisia. This defeat in Africa led to all Italian colonies in Africa being captured. The Axis had considerable success in intelligence gathering through radio communication intercepts and monitoring unit radio traffic. The most important success came through intercepting
6380-416: The British First Army had one British, one US and one French Corps (a second British Corps headquarters was activated in April). In the second half of February, in eastern Tunisia, the Axis had some successes against the mainly inexperienced French and US troops, most notably in routing the US II Corps commanded by Major General Lloyd Fredendall at the Battle of Kasserine Pass . By the beginning of March,

The landings started on 8 November, and finished on 16 November. In an attempt to pincer German and Italian forces, Allied forces (American and British Commonwealth) landed in Vichy-held French North Africa under
6612-410: The Civil War lacked standing organization at the corps and division levels, it moved swiftly to adopt these during the mobilization for the Spanish–American War in the spring of 1898. On 7 May, General Order 36 called for the establishment of seven "army corps" (repeating the nomenclature of the Civil War); an eighth was authorized later that month. Two of these saw action as a unit: the Fifth in Cuba and

In Civil War usages, by both sides, it was common to write out the number, thus "Twenty-first Army Corps", a practice that is usually ignored in modern histories of the war. Although the US Army in the years following

Two days later, no invasion having been launched, Mussolini ordered Marshal Graziani that, the moment German forces launched Operation Sea Lion to invade Great Britain, he was to attack. Beaten in the Battle of Britain, the German invasion never took place. On 8 September,

During this period of weakness, the Allies decided against a rapid advance into Tunisia while they wrestled with the Vichy authorities. Many of the Allied soldiers were tied up in garrison duties because of the uncertain status and intentions of the Vichy forces. By mid-November,

This greatly expanded reinforcement included the soon-to-be-renowned Ariete Armoured division under General Ettore Baldassarre . Meanwhile, the Germans hastily assembled a motorized force, whose lead elements arrived in Tripoli in February. This relatively small expeditionary force, termed

Although they tried desperately to overcome the British force at the Battle of Beda Fomm , the Italians were unable to break through, and the remnants of the retreating army surrendered. Over ten weeks Allied forces had destroyed the Italian Tenth Army and reached El Agheila, taking 130,000 prisoners of war in the process. Mussolini requested help from his German allies, while

Indeed, so successful was the Italian SIS in handling the bulk of Axis naval intelligence in the Mediterranean, that "Britain's offensive use of SIGINT was largely negated by Italy's defensive SIGINT." The Afrika Korps had the intelligence services of the 621st Signals Battalion mobile monitoring element which arrived in North Africa in late April 1941, commanded by Hauptmann Alfred Seeböhm. The 621st Signals Battalion monitored radio communications among British units. Unfortunately for

In June–July 1960, all KPVO were enlarged and consisted of: anti-aircraft missile regiments and brigades, air defense fighter regiments, radio engineering regiments and brigades, separate electronic warfare battalions, regiments and battalions of communications and logistics institutions. In many English-speaking countries and other countries influenced by British military traditions,

The attack was successfully repulsed by the Allied powers, and the enemy sustained significant damage to their weaponry. During the winter, there followed a period of stalemate during which time both sides continued to build up their forces. By the new year,

Positioned on the desert flank was the 7th Armoured Division , which would strike at the flank of the Italian force. By 16 September, the Italian force had advanced to Maktila , around 130 kilometres (80 mi) west of Mersa Matruh, where they halted due to supply problems. Despite Mussolini urging them to carry on, Graziani ordered his men to dig in around Sidi Barrani , and fortified camps were established in forward locations; additional troops were also positioned behind
8468-577: The army. Major General George B. McClellan , for example, planned to organize the Army of the Potomac into corps of two or more divisions and about 25,000 soldiers. However, he delayed doing so, partly for lack of experienced officers, and partly for political reasons, until March 1862 when President Lincoln ordered their creation. The exact composition of a corps in the Union Army varied during

Nevertheless, Vichy French forces put up a strong and bloody resistance to the Allies in Oran and Morocco , but not in Algiers , where a coup d'état by the French resistance on 8 November succeeded in neutralizing the French XIX Corps before the landing and arresting the Vichy commanders. Consequently, the landings met no practical opposition in Algiers, and

After three days of talks and threats, Generals Mark Clark and Dwight Eisenhower compelled Vichy Admiral François Darlan and General Alphonse Juin to order the cessation on 10–11 November of armed resistance from Vichy forces in Oran and Morocco, promising to make Darlan the head of a Free French administration. During Operation Torch, Americans fought Vichy French and German navy vessels in
9048-460: The compromised "Black Code" which the Axis forces had been reading, so the Axis could no longer learn of British "strengths, positions, losses, reinforcements, supply, situation, plans, morale etc" as they had since 1940. General Auchinleck, although he had checked Rommel's advance at the First Battle of El Alamein, was replaced by General Harold Alexander . Lieutenant-General William Gott
9164-556: The corps formed during World War I (I and III Corps) and World War II (XVIII Airborne Corps). On 12 February 2020, it was announced that the Army was reactivating V Corps to bolster the presence of US forces in Europe. The first field corps in the United States Army were legalized during the American Civil War by an act of Congress on 17 July 1862, although the term had been used previously to refer to any large portion of
9280-432: The corps. This meant that either civilian workers had to be hired or line soldiers detailed from their units to carry out the necessary tasks. Initially, corps were numbered in relation to their field army, such as I Army Corps, Army of the Potomac. After a while these numerical designations became unique to each corps regardless of the army to which they were assigned. Although designated with numbers that are sometimes
9396-572: The downfall of the Fascist government in Italy and the elimination of Germany's main European ally. German and Italian forces committed atrocities against prisoners of war and Jewish , Berber and Arab populations. On 10 May 1940, the Wehrmacht started the Battle of France (or Westfeldzug ). Six weeks later, France surrendered. The Armistice at Compiègne took place on 22 June 1940 leaving
9512-719: The eruption of the Philippine–American War ), and like the corps of the Civil War, their lineage ends at that point. During World War I, the American Expeditionary Forces (AEF) adopted the common European usage of designating field corps by Roman numerals . Several " corps areas " were designated under the authority of the National Defense Act of 1920 , but played little role until the Army's buildup for World War II. While some of
9628-542: The first formal combined-arms groupings of divisions with reasonably stable manning and equipment establishments. Napoleon I first used the corps d'armée in 1805. The use of the corps d'armée was a military innovation that provided Napoleon I with a significant battlefield advantage in the early phases of the Napoleonic Wars . The corps was designed to be an independent military group containing cavalry, artillery and infantry, and capable of defending against
9744-856: The hat badge and lanyard of their corps (e.g. a clerk posted to an infantry battalion would wear the hat badge of the Royal Australian Ordnance Corps but would wear the lanyard of the battalion they are posted to). In Canada , with the integration of the Canadian Army into the Canadian Forces , the British corps model was replaced with personnel branches , defined in Canadian Forces Administrative Orders (CFAOs) as "...cohesive professional groups...based on similarity of military roles, customs and traditions." CFAO 2-10) However,
9860-496: The line, an armoured reconnaissance soon became a full-fledged offensive from El Agheila in March. In March–April, Allied forces were forced back and leading general officers captured. The Australian 9th Infantry Division fell back to the fortress port of Tobruk, and the remaining British and Commonwealth forces withdrew a further 160 kilometres (100 mi) east to the Libyan–Egyptian border. With Tobruk under siege by
9976-466: The losses of the Italian Navy at the Battle of Cape Matapan . To conceal the fact that German coded messages were being read, a fact critical to the overall Allied war effort, British command required a flyover mission be carried out before a convoy could be attacked in order to give the appearance that a reconnaissance flight had discovered the target. The North African campaign was often labeled
10092-474: The lower numbered corps were used for various exercises, the inter-war years corps served mostly as a pool of units. During that war, the Marine Corps organized corps headquarters for the first time, the I Marine (later III Amphibious Corps ) and V Amphibious Corps . The Army ultimately designated 25 field corps (I–XVI, XVIII–XXIV, XXXVI, and I Armored Corps ) during World War II. After the Korean War ,
10208-516: The main Italian-German force, a small battlegroup continued to press eastwards. Capturing Fort Capuzzo and Bardia in passing, it then advanced into Egypt, and by the end of April it had taken Sollum and the tactically important Halfaya Pass . Rommel garrisoned these positions, reinforcing the battle-group and ordering it onto the defensive. Though isolated on land, Tobruk's garrison continued to receive supplies and replacements, delivered by
10324-435: The main force. In response to the dispersed Italian camps, the British planned a limited five-day attack, Operation Compass , to strike at these fortified camps one by one. The British Commonwealth force, totalling 36,000 men, attacked the forward elements of the 10-division-strong Italian army on 9 December. Following their initial success, the forces of Operation Compass pursued the retreating Italian forces. In January,
10440-422: The name of the new German commander, his time of arrival, and the numbers and condition of the Axis forces, but they might not correctly reveal Rommel's intentions. The primary benefit of Ultra intercepts to the effort in North Africa was to aid in cutting the Axis supply line to Tunisia. Ultra intercepts provided valuable information about the times and routes of Axis supply shipments across the Mediterranean. This
10556-464: The number is often indicated in Roman numerals (e.g., VII Corps ). The Australian and New Zealand Army Corps was raised in 1914, consisting of Australian and New Zealand troops, who went on to fight at Gallipoli in 1915. In early 1916, the original corps was reorganized and two corps were raised: I ANZAC Corps and II ANZAC Corps . In the later stages of World War I, the five infantry divisions of
10672-503: The place of the corps before and during World War II . An example would be Independent Operational Group Polesie . The groups, as the name indicates, were more flexible and showed greater capacity to absorb and integrate elements of broken units over a period of just a couple days and keep cohesion during the September Campaign than more traditional army units such as divisions, regiments, or even brigades. Wellington formed
10788-648: The plan. Marshall and other U.S. generals advocated the invasion of northern Europe later that year, which the British rejected. After Prime Minister Winston Churchill pressed for a landing in French North Africa in 1942, Marshall suggested instead to President Franklin D. Roosevelt that the U.S. abandon the Germany first strategy and take the offensive in the Pacific. Roosevelt said it would do nothing to help Russia. With Marshall unable to persuade
10904-612: The reinforcements were Italian and therefore it was up to the Italians to do the bulk of the fighting. The forward Allied force – now named XIII Corps – adopted a defensive posture and over the coming months was built up, before most of its veteran forces were redeployed to Greece to counter the German invasion there. In addition, the 7th Armoured Division was withdrawn to the Nile delta. The veteran forces were replaced by inexperienced newcomers, ill-equipped to face German armour. Although Rommel had been ordered to simply hold
11020-736: The remainder of Australia. I Corps headquarters was later assigned control of the New Guinea campaign . In early 1945, when I Corps was assigned the task of re-taking Borneo , II Corps took over in New Guinea. Canada first fielded a corps-sized formation in the First World War; the Canadian Corps was unique in that its composition did not change from inception to the war's end, in contrast to British corps in France and Flanders. The Canadian Corps consisted of four Canadian divisions. After
11136-416: The remoteness of Allied airfields from the front line gave the Axis clear air superiority over the battlefield. The Allies were halted and pushed back having advanced eastwards to within 30 kilometres (19 mi) of Tunis. In early December, the Allies were met with the reality that they would not be successful in capturing the key cities of Tunis and Bizerta. The air campaigns by the Axis forces proved to be
11252-534: The reports of Fellers, the US military attaché in Egypt. He had been tasked by Marshall with providing detailed reports on the military situation in Africa. Fellers talked with British military and civilian headquarters personnel, read documents and visited the battlefront. Known to the Germans as "die gute Quelle" (the good source) or more jokingly as 'the little fellow', he transmitted his reports back to Washington using
11368-466: The rest of the corps were disbanded. In July 1947, all KPVO were renamed anti-aircraft artillery corps. In January 1949, part of these corps was reorganized into air defence areas. From December 1948 to January 1949, all anti-aircraft artillery corps were disbanded. In June 1954, for the defense of the main industrial and economic centers and regions of the USSR, 10 air defence corps were re-created. At
11484-905: The same as those found in the modern US Army, there is no direct lineage between the 43 Union field corps of the Civil War and those with similar names in the modern era, due to congressional legislation caused by the outcry from veterans of the Grand Army of the Republic during the Spanish–American War . In the Confederate States Army , field corps were authorized in November 1862. They were commanded by lieutenant generals, and were usually larger than their Union Army counterparts because their divisions contained more brigades, each of which could contain more regiments. All of
11600-458: The same time, in addition to anti-aircraft artillery formations, fighter aviation regiments and divisions were included in the corps. Since the late 1950s, anti-aircraft artillery units have been replaced by anti-aircraft missile formations and formations of radio engineering troops. Searchlight and barrage balloon units were also abolished. In the Warsaw Pact countries, groupings similar to
11716-412: The senior-most artillery officer. In general, the other field armies tended to model their organization after the Army of the Potomac, including the gradual development of corps. Corps were commanded by major generals because Congress refused to promote officers past that grade (with the exception of Ulysses S. Grant to lieutenant general in 1864). To assist with their command, generals were allowed
11832-472: The small port at Bardia was taken, soon followed by the seizure of the fortified port of Tobruk . Some 40,000 Italians were captured in and around the two ports, with the remainder of the Tenth Army retreating along the coast road back to El Agheila . Richard O'Connor sent the 7th Armoured Division across the desert with a small reconnaissance group. It reached Beda Fomm some ninety minutes before
11948-482: The war, the tank and mechanized corps were re-rated as divisions. During the reforms of 1956–58, most of the corps were again disbanded to create the new combined arms and tank armies. A few corps were nevertheless retained. The Vyborg and Archangel Corps of the Leningrad Military District were smaller armies with three low-readiness motorized rifle divisions each. In the 1980s "Unified Corps" on
12064-413: The war, though it usually consisted of between two and six division (on average three) for approximately 36,000 soldiers. After Ambrose Burnside was given command of the Army of the Potomac in November 1862, he reorganized it into three "grand divisions" of two corps and a cavalry division each, but this structure was abolished when Joseph Hooker took over February 1863. This also led to the creation of
12180-609: Was a compromise operation that met the British objective of securing victory in North Africa while allowing American armed forces the opportunity to engage in the fight against Nazi Germany on a limited scale. In addition, as Joseph Stalin , the leader of the Soviet Union , had long been pleading for a second front to be opened to engage the Wehrmacht and relieve pressure on the Red Army , it provided some degree of relief for
12296-421: Was also a brigade of Free French under Marie-Pierre Koenig . The new formation launched a new offensive, Operation Crusader , in November. After a see-saw battle, the 70th Division garrisoning Tobruk was relieved and the Axis forces were forced to fall back. By January 1942, the front line was again at El Agheila. After receiving supplies and reinforcements from Tripoli, the Axis attacked again, defeating
12412-574: Was apparently unable to handle the formations, and the armies and corps were integrated. Rifle corps were re-established during the war after Red Army commanders had gained experience handling larger formations. Before and during World War II, however, Soviet armoured units were organized into corps. The pre-war mechanized corps were made up of divisions. In the reorganizations, these "corps" were reorganized into tank brigades and support units, with no division structure. Owing to this, they are sometimes, informally, referred to as "brigade buckets". After
12528-510: Was created to manage operations at Gallipoli while the Salonika Army managed operations at Salonika. Both armies came under the direction of the MEF, which was also responsible for the defence of Egypt . The Dardanelles Army was short-lived as, by the time of its creation, offensive operations at Gallipoli had ceased and plans for the evacuation were being made. For most of its existence,
12644-432: Was critical in providing the British with the opportunity to intercept and destroy them. During the time when Malta was under heavy air attack, the ability to act on this information was limited, but as Allied air and naval strength improved, the information became instrumental to Allied success. It is estimated that 40% to 60% of Axis supply shipping was located and destroyed due to decrypted information. However, this claim
12760-883: Was destroyed and the German Afrika Korps was dispatched to North Africa in February 1941 in Operation Sonnenblume to reinforce the Italians and prevent an Axis defeat. Battles for control of Libya and Egypt followed, with advances and retreats until the Second Battle of El Alamein in October 1942 when the Eighth Army (Lieutenant-General Bernard Montgomery ) defeated the German–Italian Panzerarmee Afrika and forced its remnants into Tunisia. After Operation Torch ,
12876-748: Was held at corps, or army level or higher. The corps became the basic tactical unit of the NRA having strength nearly equivalent to an allied division . The modern People's Liberation Army Ground Force group army ( 集团军 ) is the closest equivalent of a corps. After the military reforms of the early 2010s, a typical PLA group army consists of six combined arms brigades, plus additional artillery, air defence, engineering, sustainment, special operations and army aviation assets. Each formation contains approximately 30,000 combat troops and several thousands more supporting personnel. The French Army under Napoleon I used corps-sized formations ( French : corps d'armée ) as
12992-463: Was promoted from XIII Corps commander to command of the entire Eighth Army, but he was killed when his aircraft was intercepted and shot down over Egypt. He was replaced by Lieutenant-General Bernard Montgomery . At the end of June, Axis forces made a second attempt to break through the Allied defences at El Alamein at Alam Halfa , but were unsuccessful. After a lengthy period of build-up and training,
13108-858: Was relieved of command and replaced by Claude Auchinleck . The Western Desert Force was reinforced with a second corps, XXX Corps , with the two corps forming the Eighth Army . Eighth Army was made up of army forces from the Commonwealth nations, including the British Army , the Australian Army , the Indian Army , the New Zealand Army , the South African Army , and the Sudan Defence Force . There
13224-456: Was that Ultra intercepts had informed Wavell that OKW had clearly directed Rommel not to take any offensive action, but to wait until he was further reinforced with the 15th Panzer Division in May. Rommel received this information, but placed more value on his own assessment of the situation. Trusting that the Germans had no intention of taking major action, the British command did not respond until it
13340-500: Was too late. Furthermore, Rommel did not generally provide OKW or the Italian Comando Supremo details of his planned operations, for he thought the Italians too prone to leak the information. Thus on 21 January 1942, when Rommel struck out on his second offensive from El Agheila, Comando Supremo was just as surprised to learn of it as the British were. Ultra intercepts provided the British with such information as
13456-413: Was used almost in all European armies after Battle of Ulm in 1805. In Prussia it was introduced by Order of His Majesty ( German : Allerhöchste Kabinetts-Order ) from 5 November 1816, in order to strengthen the readiness to war. The Indian Army has 14 corps , each commanded by a general officer commanding (GOC), known as the corps commander, who holds the rank of lieutenant general . Each corps
