154-791: 13th Corps was a corps -sized formation of the British Army that fought on the Western Front during the First World War and was reformed for service during the Second World War , serving in the Mediterranean and Middle East throughout its service. 13th Corps was formed in France on 15 November 1915 under Lieutenant-General Walter Congreve to be part of Fourth Army . It was first seriously engaged during
308-582: 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
462-569: 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
616-457: 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
770-518: 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.

924-477: 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
1078-407: 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
1232-500: 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
1386-738: A defensive posture as Middle East Command focused on the Battle of Greece . The Italian forces in North Africa were reinforced with the Afrika Corps . Axis forces , now commanded by Erwin Rommel , counterattacked.

1540-511: 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,
1694-500: A linkup with the Americans to the south. At Paestum , the two lead battalions of the 36th (Texas) Division (from the 141st and 142nd Infantry Regiments ) received stiff resistance from two companies of the von Doering group. German observers on Monte Soprano directed fire onto the landing craft. LST 336 took 18 hits, and some LCTs and DUKWs sheered away to avoid German shellfire. The division had not been in combat before and as

2002-547: 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
2156-413: 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
2310-509: A rapid response to any Allied landing. In Calabria, Herr's LXXVI Panzer Corps had two divisions concentrated in the Castrovillari area. Its third division, 1st Parachute Division ( 1. Fallschirmjäger-Division ), was deployed toward Taranto. The rearguard in the toe was BattleGroup von Usedom, comprising a single battalion (1/67th Panzergrenadier Regiment) with detachments of artillery and engineers. Meanwhile, Balck's XIV Panzer Corps
2464-455: A result of the Italian surrender, there was a general belief amongst the soldiers that the landings would be routine. The 141st Infantry lost cohesion and failed to gain any depth during the day which made the landing of supporting arms and stores impossible, leaving them without artillery and anti-tank guns. However, the 142nd Infantry fared better and with the support of the 143rd Infantry ,
2618-399: 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

In addition, it would tie down German forces in Italy. Joseph Stalin , the Soviet leader , had been strongly pressuring Churchill and Roosevelt to open a "second front" in Europe, which would lessen the German Army 's focus on the Eastern Front , where
2926-440: A two-battalion drop at Capua to block the highway there. The Italian surrender on 3 September led to the cancellation of Operation Giant I and its replacement by Operation Giant II, a drop of the 504th Parachute Infantry Regiment on Stazione di Furbara and Cerveteri airfields, 40 kilometres (25 mi) northwest of Rome. This was intended to aid Italian forces in saving Rome, one of the most culturally significant cities in

On 14 September and the following night, Tedder ordered every available aircraft to support the Fifth Army, including the strategic bomber force. Over 1,000 tons of bombs were dropped during the daylight hours. On 15 September both the 16th Panzer and 29th Panzergrenadier Divisions went on the defensive, marking the end to

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
3696-480: 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

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

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
4312-664: The Oberkommando der Wehrmacht that the Allied air and naval superiority had forced LXXVI Panzer Corps onto the defensive, and that a decisive success would depend on the attack by XIV Panzer Corps. If this failed, the 10th Army must break off the battle to avoid being 'mangled'. On 16 September, the Schmalz group renewed its efforts on the X Corps front but with no more success, although No. 2 Commando suffered casualties, including 31-year-old Captain Henry Wellesley ,
4466-455: The 16th Panzer Division had organised his forces into four mixed arms battle groups which he had placed roughly 10 km (6 mi) apart and between 5 and 10 km (3 and 6 mi) back from the beaches. The Dőrnemann group was just east of Salerno (and therefore were opposite Major General John Hawkesworth 's British 46th Infantry Division when it landed), the Stempel battle group
4620-471: The 1st Canadian and British 5th Infantry Divisions , launched Operation Baytown under General Bernard Montgomery 's direction. Opposition to the landings was light and the Italian coastal units surrendered almost immediately. Except to the Italian paratroopers of the 185th Infantry Regiment "Nembo" which was attached to the 211th Coastal Division had provided stiff resistance in the Aspromonte, but
4774-598: The 1st Canadian Armoured Brigade , made a successful strongly opposed night crossing of the Garigliano and Rapido rivers, and broke into the heart of the German defenses in the Liri valley. This victory was of enormous significance as it collapsed or bypassed the German defenses of Gustav Line and led to the capture of Rome. On 17 August 1944, 13th Corps was transferred to the U.S. Fifth Army to become its right wing. Under

The new German 10th Army headquarters, commanded by Heinrich von Vietinghoff , was activated on 22 August. The German 10th Army had two subordinate corps with a total of six divisions which were positioned to cover possible landing sites. Under Hermann Balck 's XIV Panzer Corps was the Hermann Göring Airborne Panzer Division (under Wilhelm Schmalz ), 15th Panzergrenadier Division ( Eberhard Rodt ) and 16th Panzer Division ( Rudolf Sieckenius ); and under Traugott Herr 's LXXVI Panzer Corps

The build-up across the Straits of Messina had proved slow; he was therefore short of transport and decided to halt his formations to reorganize before pushing on. However, General Alexander issued orders on 10 September that "It is of the utmost importance that you maintain pressure upon the Germans so that they cannot remove forces from your front and concentrate them against Avalanche". This message

The British Commandos captured the town of Salerno after some serious fighting that cost 40 (Royal Marine) Commando and 41 Commando nine killed and thirty-seven wounded. The two British infantry divisions, however, met determined resistance and had to fight their way ashore with the help of naval bombardments. The depth and intensity of German resistance forced British commanders to concentrate their forces, rather than driving for

The British X Corps, composed of the British 46th and 56th Infantry Divisions and a light infantry force of U.S. Army Rangers and British Commandos of Brigadier Robert "Lucky" Laycock's 2nd Special Service Brigade , experienced mixed reactions to its landings. The U.S. Rangers met no opposition and with support from
8470-448: The Allied build-up was constrained by the limited transport available for the operation and the pre-determined schedule of the build-up based on how, during the planning phase, it had been anticipated the battle would develop. By 12 September, it had become clear that the Fifth Army had an acute shortage of infantry on the ground. That day, General Sir Harold Alexander , the 15th Army Group commander, reported to General Sir Alan Brooke ,
8624-453: The Allies' speed of advance was entirely dependent on the rate at which their engineers could clear obstructions. Thus, Montgomery's objections to the operation were proved correct: the Eighth Army could not tie down German units that refused battle and the main obstacle to their advance was the terrain and German demolitions of roads and bridges. By 8 September, Kesselring had concentrated Heinrich von Vietinghoff 's 10th Army , ready to make

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

After an initial attack that made no headway, the Krüger Battle Group veered away but the northern attack continued throughout the day before the whole German force withdrew at dusk. Progress was slow as demolished bridges, roadblocks and mines delayed the Eighth Army. The nature of the countryside in the toe of Italy made it impossible to by-pass obstacles and so

The German forces in Italy were prepared for this and implemented Operation Achse to disarm Italian units and occupy important defensive positions. Operation Slapstick commenced on 9 September. The first echelon of the British 1st Airborne Division arrived on four British cruisers, a U.S. cruiser, and the British fast minelayer HMS Abdiel . The Italian battleships Andrea Doria and Duilio with two cruisers passed by, en route to surrender in Malta. There were no Germans in Taranto and so disembarkation

The U.S. 82nd Airborne Division, after suffering serious casualties near Altavilla , was merged with British X Corps, joining the U.S. Army Rangers and the British 23rd Armoured Brigade on the Sorrento Peninsula to flank the German defenses at Nocera Inferiore , Sant'Antonio Abate , and Angri , which
11704-601: The Western Desert. In August 1941 Archibald Wavell was replaced as C-in-C Middle East by Claude Auchinleck and the British and other Commonwealth forces were reinforced to create in September 1941 the British Eighth Army . During this reorganisation, Western Desert Force was once again redesignated as 13th Corps and became part of the new army. The Corps remained part of the Eighth Army throughout
11858-620: The afternoon, two German battlegroups, the Kleine Limburg and the Krüger, had attacked Persano and overrun the 1st Battalion, 157th Infantry before crossing the Sele to engage the 2nd Battalion of the 143rd Infantry and virtually wipe it out. The battle groups continued their strike south and south-west until reaching the confluence of the Sele and its large tributary the Calore, where it
12012-433: The alternative Operation Seatrain envisioned shifting VI Corps to the X Corps sector. The navy protested that reversing the landing process would be impossible since loading beached landing craft would make them heavier and unable to withdraw from the beach. Advice from superiors and subordinates convinced Clark to continue fighting, and he later denied seriously considering evacuation. The U.S. VI Corps had by this time lost
12166-518: The amphibious force commander, had predicted, tactical surprise was not achieved. As the first wave of Major General Fred L. Walker 's U.S. 36th Infantry Division approached the Paestum shore at 03:30 a loudspeaker from the landing area proclaimed in English: "Come on in and give up. We have you covered." The Allied troops attacked nonetheless. Major General Rudolf Sieckenius , commander of
12320-577: 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
12474-603: The axis" (American General Mark W. Clark would later call it "one tough gut"). Churchill noted that Italian popular support for the war was declining and an invasion would remove Italy from the Axis, thus weakening Axis influence in the Mediterranean Sea and opening it to Allied traffic. This would allow the reduction of shipping capacity needed to supply Allied forces in the Middle East and Far East theaters at
12628-404: The battlefield. Units, short of transport and subjected to other delays, arrived piecemeal and were formed into ad hoc battle groups for immediate action. By 13 September, all the immediately available reinforcements had arrived including additional elements from the 3rd Panzergrenadier Division which had been released by Generalfeldmarschall Kesselring from further north near Rome. By contrast,
12782-667: The best part of three battalions, and so the forward units of both its divisions were withdrawn to reduce the length of the defensive line. The 45th Division consolidated at the Sele - Calore position while the 36th Division was on the high ground on the seaward side of the La Caso stream (which flowed into the Calore). The new perimeter was held with the assistance of Major General Matthew Ridgway 's 82nd Airborne Division . Two battalions (roughly 1,300 paratroopers ) of Colonel Reuben Tucker 's 504th Parachute Infantry Regiment (PIR), after
12936-629: The brigade pattern were created in the Belorussian Military District (Western TVD/Strategic Direction) and the 48th Separate Guards Army Corps in the Transbaikal Military District , but abandoned after a few years. The Soviet Air Forces used ground terminology for its formations down to squadron level. As intermediates between the aviation division and the air army were corps—these also had three air divisions each. An Air Defence Corps ('KPVO')
13090-739: The bulk of its forces were fighting in the largest armed conflict in history against the Soviet Red Army . However, U.S. Army Chief of Staff General George C. Marshall and much of the American staff wanted to avoid operations that might delay the main invasion of Europe, which had been planned as early as 1942, and which finally materialized as Operation Overlord in 1944. When it became clear that no cross-channel invasion of occupied France could be undertaken in 1943, both parties agreed to an invasion of Sicily , codenamed Operation Husky , with no commitment made to follow-up operations. After
13244-422: The cancellation of Giant II, had been assigned to execute the final version of Operation Giant I at Capua on the evening of 13 September. Instead, they jumped inside the beachhead, guided by Rebecca/Eureka beacons and moved immediately into the line on the right of VI Corps. The next night, with the crisis past, 2,100 paratroops of Colonel James Gavin 's 505th PIR also parachuted into the beachhead and reinforced
13398-438: The coast from Bagnara. On 4 September, the British 5th Infantry Division reached Bagnara Calabra , linked up with 1st Special Reconnaissance Squadron (which arrived by sea) and drove the 3rd Battalion, 15th Panzergrenadier Regiment from its position. On 5 September the allies flew above Soveria Mannelli (central Calabria ) and bombed all along the downstream area of the town, where Nazi bases and warehouses stood. Fortunately,
13552-462: The command of Vice Admiral Henry K. Hewitt . Following the disappointing air cover from land-based aircraft shown during the battle of Gela in the Sicily landings, Force V of HMS Unicorn and four escort carriers augmented the cruisers USS Philadelphia , Savannah , Boise , and fourteen destroyers of Hewitt's command. Cover for the task force was provided by Force H under
13706-500: The command of Vice Admiral Algernon Willis, a group of four British battleships and two fleet carriers with destroyers, which was directly subordinate to the C–in–C Mediterranean Admiral Sir Andrew Cunningham . In the original planning, the great attraction of capturing the important port of Taranto in the "heel" of Italy had been evident and an assault had been considered but rejected because of
13860-503: 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
14014-432: 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
14168-416: The defenders, from Traugott Herr 's LXXVI Panzer Corps , were too scattered for it to be effective.) The element of surprise was further limited by belated discovery of naval minefields off Salerno requiring landing craft to spend two hours traveling 19 km (12 mi) from the transports to the landing beaches. On the German side, Kesselring lacked the strength to push the Salerno landing back, and
14322-719: 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
14476-521: The fighting in the North African campaign . Eventually, the corps commander, Lieutenant-General Richard McCreery , persuaded about half of the men to follow their orders. The remainder were court-martialled . Three NCOs who led the mutiny were sentenced to death but the sentence was not carried out and they were eventually allowed to rejoin units. With the Salerno beachhead secure, the Fifth Army began its attack northwest towards Naples on 19 September. On 20 September, Major General Ernest J. Dawley ,
14630-625: The first Allied unit to do so. The entire Fifth Army, now consisting of five American and three British divisions, reached the line of the Volturno River on 6 October. This provided a natural defensive barrier, securing Naples, along with the Campanian plain and the vital airfields on it, from a German counterattack. Meanwhile, on the Adriatic Coast , the Eighth Army advanced to a line from Campobasso to Larino and Termoli on
14784-542: 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
14938-473: The guns of HMS Ledbury seized their mountain pass objectives while the Commandos, from No. 2 (Army) Commando and No. 41 (Royal Marine) Commando , were also unopposed and secured the high ground on each side of the road through Molina Pass on the main route from Salerno to Naples. At first light units of No. 2 Commando moved towards Salerno and pushed back a small force of tanks and armoured cars from
15092-856: 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,
15246-536: The high ground inland left the airfield within easy range of German artillery and therefore unusable by Allied aircraft. On 10 September, German bombers began targeting Admiral Hewitt's flagship USS Ancon while the ship was serving as General Clark's headquarters. The flagship called thirty "red alerts" over a period of 36 hours in response to 450 Luftwaffe flying sorties. Admiral Hewitt reported: "Air situation here critical." The Allied aircraft carriers had intended to withdraw on 10 September, but remained with
15400-683: The highly successful outcome of the Sicilian campaign had become clear, both Churchill and Franklin D. Roosevelt , the U.S. President , accepted the necessity of continuing to engage the Axis before the start of the campaign in northwest Europe . Discussions had been ongoing since the Trident Conference held in Washington, D.C., in May, but it was not until late July, with the fall of Italian Fascist Prime Minister Benito Mussolini , that
15554-461: The invasion so that their Supermarine Seafires could provide the air cover which invasion planners had expected to operate from Montecorvino. Eighty-five Allied vessels were hit by German bombs off Salerno. Fritz X glide bombs dropped by Dornier Do 217s disabled USS Savannah and narrowly missed USS Philadelphia on the morning of 11 September. The following morning, Clark moved his headquarters ashore, and Hewitt transferred with his staff to
15708-520: The island of Sicily into the "arch" area ( Taranto ) of the Italian mainland, envisioning a limited invasion of the Italian "boot", whence they would advance up the western coast, anticipating a strong defense by both German and Italian forces. The overthrow of Mussolini made a more ambitious plan feasible, and the Allies decided to make their invasion two-pronged by combining the crossing of the British Eighth Army under General Sir Bernard Montgomery into
15862-528: The lines in the vicinity of Avellino was widely dispersed and failed, incurring significant casualties. In the X Corps sector the lead elements of Major General George Erskine 's British 7th Armoured Division began to land, along with the 23rd Armoured Brigade . With strong naval gunfire support from the Royal Navy and well-served by Fifth Army's artillery, the reinforced and reorganized infantry units defeated all German attempts on 14 September to find
16016-474: 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 ,
16170-482: The main attack was on the boundary between the two Allied Corps which ran roughly from Battipaglia to the Tyrrhenian sea, with the greatest weight due to fall on the VI Corps side On the morning of 13 September, elements of Major General Walker's 36th Division attacked and captured Altavilla from the high ground 14 km (9 mi) behind Paestum, but a counterattack forced them to withdraw as darkness fell. During
16324-498: The mainland with the simultaneous seizure of the port of Naples further north. Although the Americans were mindful of Napoleon 's maxim that Italy, like a boot, should be entered from the top, the range limits of Allied fighter aircraft based in Sicily reduced their choices to two landing areas: one at the Volturno River basin to the north of Naples and the other south of Naples at Salerno (though separated from Naples by
16478-476: The mountain passes of the Sorrento Peninsula above Salerno was abandoned on 12 August. Six days later it was replaced by Operation Giant, in which two regiments of the U.S. 82nd Airborne Division (Major General Matthew Ridgway ) would seize and hold crossings over the Volturno River. This was at first expanded to include the entire division, including an amphibious landing by the 325th Glider Infantry Regiment , then deemed logistically unsupportable and reduced to
16632-665: The mountainous Sorrento peninsula). They chose Salerno because it was closer to their air bases. Operation Baytown was the preliminary step in the plan in which the British Eighth Army would depart from the port of Messina , Sicily, across the narrow Straits and land near the tip of Calabria (the "toe" of Italy), on 3 September 1943. The short distance meant landing craft could launch from there directly, rather than be carried by ship. The British 5th Infantry Division (Major-general Gerard Bucknall ) of XIII Corps , under Lieutenant-General Miles Dempsey , would land on
16786-473: The north side of the "toe" while its 1st Canadian Infantry Division (Major-General Guy Simonds ) would land at Cape Spartivento on the south side. Montgomery was strongly opposed to Operation Baytown. He predicted it would be a waste of effort since it assumed the Germans would give battle in Calabria; if they failed to do so, the diversion would not work, and the only effect of the operation would be to place
16940-464: 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
17094-503: 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
17248-589: The plain to the right of the Sele river and the higher ground to a depth of 8 km (5 mi), although the 141st Infantry was still stuck near the beach. However, the XIV Panzer Corps commander, Hermann Balck, had seen the 16th Panzer Division's battle groups perform as intended and he had ordered both the Hermann Göring Division south to the battle and later in the day had been able to order 15th Panzergrenadier likewise. Meanwhile, to
17402-467: The power to neutralize it. The 10th Army had succeeded in preventing troops from being cut off, and continuing the battle would invite heavy losses. The approach of the Eighth Army was also posing a threat. He recommended breaking off the battle, pivoting on Salerno to form a defensive line, preparatory to a withdrawal on 18/19 September. Kesselring's agreement reached von Vietinghoff early on 17 September. General Hermann Balck, commanding XIV Panzer Corps -
17556-432: The previous day, as did the naval bombardment. The arrival of the British battleships HMS Warspite and Valiant , with 381 mm (15 in) guns, off the beaches provided the Allied troops with a morale boost, although Valiant was not required to shoot and Warspite ' s 29 rounds were awe-inspiring but a minor contribution to the 2,592 naval rounds fired that day. On 15 September, Kesselring reported to
17710-468: The principal armoured formation near Salerno - wrote that his tanks ‘suffered heavily under Allied naval gunfire, with which [they] had nothing to counter'. This triggered an Axis forces retreat from areas which were covered by Allied naval gunfire. General von Vietinghoff then reported to his superior that his attacks ‘were unable to reach their objective owing to the fire from naval guns and low-flying aircraft'. Allied air and naval support lines, aided by
17864-683: 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
18018-465: The reserve formation which had landed by 08:00, were able to push forward. Minesweepers cleared an inshore channel shortly after 09:00; so by late morning destroyers could steam within 90 m (100 yd) of the shoreline to shell German positions on Monte Soprano. USS Philadelphia and Savannah focused their 15 cm (6 in) guns on concentrations of German tanks, beginning a barrage of naval shells which would total eleven-thousand tons before
18172-654: The rest of the North African Campaign , which finally ended in May 1943. Still part of the Eighth Army, 13th Corps, now under command of Miles C. Dempsey , then took part in the Allied invasion of Sicily in July 1943. By now it had the 5th and 50th Infantry divisions under command. Now with the 1st Canadian Infantry and 5th Infantry divisions, 13th Corps took part in the Allied invasion of Italy , executing Operation Baytown on 3 September 1943, part of
18326-466: 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
18480-603: The river, offering the Germans an easy route to attack, and only belatedly landed two battalions to protect it. Furthermore, the terrain was highly favorable to the defender. Planning for the Salerno phase was accomplished in only forty-five days, rather than the months that might be expected. A U.S. Army Ranger force, under the command of Lieutenant Colonel William O. Darby , consisting of three U.S. Ranger battalions (the 1st , 3rd and 4th ), and two British Commando units, under Brigadier Robert Laycock (consisting of No. 2 (Army) Commando and No. 41 (Royal Marine) Commando ),
18634-905: 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
18788-458: 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
18942-412: 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
19096-481: The small amphibious force flagship USS Biscayne so the large Ancon could retire to North Africa. The Allies fought to expand their beachhead for three days while the Germans defended stubbornly to mask the build-up of their reinforcements for a counter-offensive. On 10 September, Clark visited the battlefield and judged that it was unlikely that X Corps would be able to push quickly east past Battipaglia to link with VI Corps. Since X Corps' main line of thrust
19250-486: The south, the 29th Panzergrenadier Division from LXXVI Panzer Corps had also been directed to Salerno. Neither side had gained the initiative. Luftwaffe planes began strafing and bombing the invasion beaches shortly after 04:00 on the morning of 9 September before X Corps seized the Montecorvino airfield 5 km (3 mi) inland later that day, destroying three dozen German planes. However, failure to capture
19404-400: The then-Duke of Wellington, who was killed. The Allied air forces and navies continued to batter enemy targets, although during an air attack by Dornier Do 217 K-2 bombers armed with Fritz X radio-controlled glide bombs, Warspite was hit and disabled, which required her to be towed to Malta for repair. On 9 September, Montgomery's formations had been strung out along the coastal roads in
19558-646: The thrust towards Paestum. Further north the Schmalz group of the Hermann Göering Division achieved surprise, attacking the 128th (Hampshire) Brigade (comprising three battalions, the 2nd, 1/4th and 5th, of the Hampshire Regiment ), of the British 46th Division, on the high ground east of Salerno. The armoured column following up was intercepted and driven back, leaving the German infantry exposed. The Allied bomber effort continued on 15 September, although slightly less intensively than
19712-470: The two battalions of the 504th. A clear sign of the crisis passing was when, on the afternoon of 14 September, the final unit of 45th Division, the 180th Infantry Regiment , landed, Clark was able to place it in reserve rather than in the line. The 325th Glider Infantry Regiment , reinforced by the 3rd Battalion, 504th PIR, landed by sea on 15 September. A night drop of 600 paratroops of the 509th Parachute Infantry Battalion to disrupt German movements behind
19866-526: The urban area was barely damaged. On 7 September, contact was made with the Krüger Battle Group. On 8 September, the 231st Independent Brigade Group , under Brigadier Robert "Roy" Urquhart , was landed by sea at Pizzo Calabro , 24 km (15 mi) behind the Nicotera defenses. They found themselves attacked from the north by a mobile force from 26th Panzer Division and from the south by
20020-602: The very strong defenses there. However, with the signing of the armistice with the Italians on 3 September, the picture changed. It was decided to carry the British 1st Airborne Division (Major-General George Hopkinson ) to Taranto using British warships, seize the port and several nearby airfields and follow up by shipping in Lieutenant-General Charles Allfrey 's British V Corps and a number of fighter squadrons. The airborne division, which
20174-482: 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
20328-413: 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
20482-688: The west coast of Italy at Salerno on 9 September as part of Operation Avalanche , while two supporting operations took place in Calabria ( Operation Baytown ) and Taranto ( Operation Slapstick ). Following the defeat of the Axis powers in North Africa in May 1943, there was disagreement between the Allies about the next step. British Prime Minister Winston Churchill wanted to invade Italy, which in November 1942 he had called "the soft underbelly of
20636-425: The western world, from German razing, a condition of the Italian armistice. Because the distance from the Allied beachheads precluded any substantial Allied support of the airborne troops, Brigadier General Maxwell D. Taylor , the acting assistant division commander (ADC) of the 82nd Airborne Division, was spirited into Rome to assess the willingness of Italian troops to cooperate with the Americans. Taylor's judgment
20790-400: Was 26th Panzer Division ( Heinrich Freiherr von Luttwitz ), 29th Panzergrenadier Division ( Walter Fries ) and 1st Parachute Division ( Fritz-Hubert Graser ). Von Vietinghoff specifically positioned the 16th Panzer Division in the hills above the Salerno plain. On 3 September 1943, the British Eighth Army 's XIII Corps , commanded by Lieutenant-General Miles Dempsey and composed of
20944-434: Was able to overcome their resistance. Albert Kesselring and his staff did not believe the Calabria landings would be the main Allied point of attack, the Salerno region or possibly even north of Rome being more logical. He had already therefore ordered General Traugott Herr 's LXXVI Panzer Corps to pull back from engagement with the Eighth Army, leaving only 29th Panzergrenadier Division 's 15th Panzergrenadier Regiment in
21098-574: 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
21252-455: Was between Pontecagnano and Battipaglia (and so faced Major General Douglas Graham 's British 56th Infantry Division ), the Holtey battle group was in a reserve role at Persano on the Sele river which formed the corps boundary between Lieutenant General Richard McCreery 's British X Corps and Major General Ernest Dawley 's U.S. VI Corps , while the von Doering battle group responsible for
21406-470: Was committed and there were no reserves available to form an attack. In the south, the 36th Division made some progress but towards midday a counterattack by elements of the 29th Panzergrenadier Division overran the 1st Battalion, 142nd Infantry Regiment. On 13 September, the Germans launched their counteroffensive. While the Hermann Göring battle groups attacked the northern flank of the beachhead,
21560-478: Was destroyed and General Pietro Maletti was killed in action while trying to stop the sudden attack. By February 1941, Operation Compass was a complete victory. When Operation Compass came to an end with the surrender of the Italian Tenth Army, 13th Corps HQ was deactivated in February and its responsibilities taken over by HQ Cyrenaica, a static command. Allied forces in the Western Desert took
21714-404: Was further reinforced on 12 September by a personal visit from Alexander's Chief of Staff , Brigadier A. A. Richardson. Montgomery had no choice- while reorganizing the main body of his troops, he sent light forces up the coast which reached Castrovillari and Belvedere on 12 September, still some 130 km (80 mi) from the Salerno battlefield. On 14 September, he was in a position to start
21868-748: 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
22022-648: Was positioned to face possible landings from the sea with 16th Panzer Division in the Gulf of Salerno, the Hermann Göring Division near Naples and the 15th Panzergrenadier Division to the north in the Gulf of Gaeta. On 8 September (before the main invasion), the armistice of Italy to the Allies was announced, first by General Eisenhower , then in the Badoglio Proclamation by the Italian government. Italian units ceased combat and
22176-474: Was redesignated "13th Corps". It then included British 7th Armoured Division , Australian 6th Infantry Division and 4th Indian Infantry Division . During the initial attack, Matilda infantry tanks of the 7th Royal Tank Regiment along with the 11th Indian Brigade of the 4th Indian Division, exploited a hole in the Italian defensive positions and attacked the Nibiewa camp from the rear. The Maletti Group
22330-541: Was refused two panzer divisions from northern Italy to assist him. Operation Avalanche was planned under the name Top Hat and supported by a deception plan, Operation Boardman, a false threat of an Allied invasion of the Balkans . In mid-August, the Germans had activated Army Group B under Erwin Rommel with responsibility for German troops in Italy as far south as Pisa . Army Command South under Albert Kesselring continued to be responsible for southern Italy and
22484-401: Was removed as head of the Italian government, envoys of which soon began approaching the Allies to make peace. It was believed a quick invasion of Italy might hasten Italian surrender and produce quick military victories over the German troops trapped fighting in a hostile country. However, Italian (and more so German) resistance proved relatively strong, and fighting in Italy continued even after
22638-507: Was stopped by artillery firing over open sights, naval gunfire and a makeshift infantry position manned by artillerymen, drivers, cooks and clerks and anyone else that Major General Walker could scrape together.
