Corps in the context of "Division (military)"

The German Army (German: Heer, German: [heːɐ̯] ; lit. 'army') was the land forces component of the Wehrmacht, the regular armed forces of Nazi Germany, from 1935 until it effectively ceased to exist in 1945 and then was formally dissolved in August 1946. During World War II, a total of about 13.6 million volunteers and conscripts served in the German Army.

Only 17 months after Adolf Hitler announced the German rearmament programme in 1935, the army reached its projected goal of 36 divisions. During the autumn of 1937, two more corps were formed. In 1938 four additional corps were formed with the inclusion of the five divisions of the Austrian Army after the annexation of Austria by Germany in March. During the period of its expansion under Hitler, the German Army continued to develop concepts pioneered during World War I, combining ground and air units into combined arms forces. Coupled with operational and tactical methods such as encirclements and "battle of annihilation", the German military managed quick victories in the two initial years of World War II, a new style of warfare described as Blitzkrieg (lightning war) for its speed and destructive power.

The Ulm campaign was a series of French and Bavarian military maneuvers and battles to outflank and capture an Austrian army in 1805 during the War of the Third Coalition. It took place in the vicinity of and inside the Swabian city of Ulm. The French Grande Armée, led by Emperor Napoleon, had 210,000 troops organized into seven corps and hoped to knock out the Austrian army in the Danube before Russian reinforcements could arrive. Rapid marching let Napoleon conduct a large wheeling maneuver, which captured an Austrian army of 60,000 under Feldmarschall-Leutnant (FML) Karl Freiherr Mack von Leiberich on 20 October at Ulm. The campaign is by some military historians regarded as a strategic masterpiece and was influential in the development of the Schlieffen Plan in the late 19th century. Napoleon himself wrote:

The victory at Ulm did not end the war since a large Russian army under Mikhail Kutuzov was near Vienna to defend the city against the French. The Russians withdrew to the northeast to await reinforcements and to link up with Austrian army units. The French moved aggressively forward and captured Vienna on 12 November. On 2 December, the massive Battle of Austerlitz, causing 24,000 to 36,000 casualties, removed Austria from the war. The resulting Treaty of Pressburg in late December brought the Third Coalition to an end and established Napoleonic France as the major power in Central Europe, which led to the War of the Fourth Coalition against the Kingdom of Prussia and Russia the following year.

The twin battles of Jena and Auerstedt (German pronunciation: [ˈjeːna … ˈaʊ̯ɐ.ʃtɛt]; older spelling: Auerstädt) were fought on 14 October 1806 on the plateau west of the river Saale in today's Germany, more specifically in today's Thuringia, between the forces of Napoleon I of France and Frederick William III of Prussia, at the outset of the War of the Fourth Coalition during the Napoleonic Wars. The disastrous defeats suffered in these battles by the Prussian Army, which had not been reformed for about half a century, subjugated the Kingdom of Prussia to the French Empire until the Sixth Coalition was formed in 1813.

The Prussians did not forget the military glory of Frederick the Great and venerated it, but by the time of the war, changes were needed for victory, despite the fact that Prussia showed itself well in the French Revolutionary Wars. Thus at Jena and Auerstedt the backwardness of the Prussian Army became apparent. By 1806, Prussian military doctrines have been unchanged for more than 50 years,—tactics were monotonous, and wagon system was obsolete. The Prussian musket of 1806 (the 1754 model) was called "the worst in Europe" by one authority; there were many recruited non-Prussians in the royal army. At the same time, Napoleon's army was recently reorganized according to the advanced corps system, which the French Emperor improved greatly by 1805. At Jena the French were led by Napoleon himself, and at Auerstedt they were led by one of the most outstanding commanders of the Napoleonic Wars, Louis-Nicolas Davout. The battle took the Prussian supreme commander at Jena, Prince of Hohenlohe-Ingelfingen, by surprise due to his misorientation and ignorance of the enemy. Due to this incompetence, the Prussians fought a series of isolated, disjointed engagements, unconnected by a unified plan. From beginning to end, Hohenlohe remained disoriented regarding the enemy's strength and direction of advance, and not only did not find time to maintain control of the battle but was unable to even organize an adequate retreat; whilst Napoleon showed firm will at Jena, skillfully taking advantage of both the weather conditions (fog) and the rugged terrain when his troops gradually entered the battle from the march.

The Battle of Waterloo was fought on Sunday 18 June 1815, near Waterloo (then in the United Kingdom of the Netherlands, now in Belgium), marking the end of the Napoleonic Wars. The French Imperial Army under the command of Napoleon I was defeated by two armies of the Seventh Coalition. One was a British-led force with units from the United Kingdom, the Netherlands, Hanover, Brunswick, and Nassau, under the command of field marshal Arthur Wellesley, Duke of Wellington. The other comprised three corps of the Prussian army under Field Marshal Blücher. The battle was known contemporaneously as the Battle of Mont Saint-Jean in France (after the hamlet of Mont-Saint-Jean) and La Belle Alliance in Prussia ("the Beautiful Alliance"; after the inn of La Belle Alliance).

Upon Napoleon's return to power in March 1815, the beginning of the Hundred Days, many states that had previously opposed him formed the Seventh Coalition to oppose him again, and hurriedly mobilised their armies. Wellington's and Blücher's armies were cantoned close to the northeastern border of France. Napoleon planned to attack them separately, before they could link up and invade France with other members of the coalition. On 16 June, Napoleon successfully attacked the bulk of the Prussian Army at the Battle of Ligny with his main force, while a small portion of the French Imperial Army contested the Battle of Quatre Bras to prevent the Anglo-allied army from reinforcing the Prussians. The Anglo-allied army held their ground at Quatre Bras but were prevented from reinforcing the Prussians, and on the 17th, the Prussians withdrew from Ligny in good order, while Wellington then withdrew in parallel with the Prussians northward to Waterloo on 17 June. Napoleon sent a third of his forces to pursue the Prussians, which resulted in the separate Battle of Wavre with the Prussian rear-guard on 18–19 June and prevented that French force from participating at Waterloo.

A field army (also known as numbered army or simply army) is a military formation in many armed forces, composed of two or more corps. It may be subordinate to an army group. Air armies are the equivalent formations in air forces, and fleets in navies. A field army is composed of 80,000 to 300,000 soldiers.

III Corps is a corps of the United States Army headquartered at Fort Hood, Texas. It is a major formation of the United States Army Forces Command.

Activated in World War I in France, III Corps oversaw US Army divisions as they repelled several major German offensives and led them into Germany. The corps was deactivated following the end of the war.

The XVIII Airborne Corps is a corps of the United States Army that has been in existence since 1942 and saw extensive service during World War II. The corps is designed for rapid deployment anywhere in the world and is referred to as "America's Contingency Corps." Its headquarters are at Fort Bragg, North Carolina.

Eurocorps (French: Eurocorps, German: Eurokorps), located in the French city of Strasbourg (Bas-Rhin), is a multinational corps headquarters. Founded by France and Germany in 1992, it is today composed of personnel from six framework nations and five associated nations. The framework nations place the Eurocorps at the service of the European Union (EU) and NATO, which certified it in 2002 as one of its nine High Readiness Land Headquarters (HRF (L) HQ).

The precedents of the Eurocorps date back to 1989, when German Chancellor Helmut Kohl and the President of the French Republic, François Mitterrand, initiated military cooperation by establishing the Franco-German Defense and Security Council and creating a joint brigade, which became operational in 1991.

The Intelligence Corps (Int Corps) is a corps of the British Army. It is responsible for gathering, analysing and disseminating military intelligence and also for counter-intelligence and security. The Director of the Intelligence Corps is a brigadier.
