Jean Victor Marie Moreau in the context of "Army corps"

Archduke Charles Louis John Joseph Lawrence of Austria, Duke of Teschen (German: Erzherzog Karl Ludwig Johann Josef Lorenz von Österreich, Herzog von Teschen; 5 September 1771 – 30 April 1847) was an Austrian field marshal, the third son of Emperor Leopold II and Maria Luisa of Spain. He was also the younger brother of Francis II, Holy Roman Emperor. He was epileptic, but achieved respect both as a commander and as a reformer of the Austrian Army. He was considered one of Napoleon's most formidable opponents and one of the greatest generals of the French Revolutionary and Napoleonic Wars. Charles wrote several military works as well.

He began his career fighting the revolutionary armies of France. Early in the wars of the First Coalition, he saw victory at Neerwinden in 1793, before being defeated at Wattignies in 1793 and Fleurus in 1794. In 1796, as chief of all Austrian forces on the Rhine, Charles defeated Jean-Baptiste Jourdan at Amberg, Würzburg and Limburg, and then won victories at Wetzlar, Emmendingen and Schliengen that forced Jean Victor Marie Moreau to withdraw across the Rhine. He also defeated opponents at Ostrach, Stockach, Zürich and Mannheim in 1799. He reformed Austria's armies to adopt the nation-at-arms principle. In 1809, he entered the War of the Fifth Coalition and inflicted Napoleon's first major setback at Aspern-Essling, before suffering a defeat at the bloody Battle of Wagram. After Wagram, Charles saw no more significant action in the Napoleonic Wars.

The Battle of Dresden (26–27 August 1813) was a major engagement of the Napoleonic Wars. The battle took place around the city of Dresden in modern-day Germany. With the recent addition of Austria, the Sixth Coalition felt emboldened in their quest to expel the French from Central Europe. Despite being heavily outnumbered, French forces under Napoleon scored a victory against the Army of Bohemia led by Generalissimo Karl von Schwarzenberg. However, Napoleon's victory did not lead to the collapse of the coalition, and the weather and the uncommitted Russian reserves who formed an effective rearguard precluded a major pursuit. Three days after the battle, the Coalition surrounded and destroyed a French corps advancing into their line of withdrawal at the Battle of Kulm.

Historian Modest Bogdanovich summarized the battle and noted the following details. 'Both the city itself and its surroundings presented a picture of anxiety and devastation. Napoleon, in turn, was justifiably proud of his success. The allies had almost double the cavalry, and they also had the advantage in artillery. Napoleon's troops consisted almost exclusively of fresh conscripts, while the allies had many veterans. But these advantages could not compensate for the lack of unity of command, the speed of common understanding, and the execution of actions. Many of the individual commanders, for example, Zieten and Colloredo, covered themselves with glory, and the troops fought very bravely, but at their head was Schwarzenberg, and at the head of the French was Napoleon. Neither even the experience of Moreau nor the profound knowledge of Jomini, the French apostates who participated on the Imperial-Russian side, could compensate for the shortcomings.'

Corps (/kɔːr/; plural corps /kɔːrz/; from French corps, from the Latin corpus "body") is a term used for several different kinds of organization. A military innovation by Napoleon I, the formation was formally introduced March 1, 1800, when Napoleon ordered General Jean Victor Marie Moreau to divide his command into four corps. Before it came into force in 1800, the idea of corps was already in its infancy (for example, Jourdan's Army of Sambre and Meuse in 1795 was divided into 3 corps), but it could not take a definite form due to the relatively small size of the individual armies. Only Moreau granted the corps legal status in 1800; Napoleon finally developed them in 1805. 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:

The French Revolutionary Army (French: Armée révolutionnaire française) was the French land force that fought the French Revolutionary Wars from 1792 to 1802. In the beginning, the French armies were characterised by their revolutionary fervour, their poor equipment and their great numbers. However, the French Revolutionary Army had become arguably the most powerful army in the world by the mid-1790s, as the French armies had become well-experienced and organized, enabling them to comfortably outfight their enemies.

Despite experiencing early disastrous defeats, the revolutionary armies successfully expelled foreign forces from French soil and then overran many neighboring countries, establishing client republics. Leading generals included Napoleon Bonaparte, Jean-Baptiste Jourdan, André Masséna, Jean Victor Marie Moreau and Étienne Macdonald.

The Battle of Hohenlinden was fought on 3 December 1800 during the French Revolutionary Wars. A French army under Jean Victor Marie Moreau won a decisive victory over an Austrian and Bavarian force led by 18-year-old Archduke John of Austria. The allies were forced into a disastrous retreat that compelled them to request an armistice, effectively ending the War of the Second Coalition. Hohenlinden is 33 km (21 mi) east of Munich in modern Germany.

General of Division Moreau's 56,000-strong army engaged some 64,000 Austrians and Bavarians. The Austrians, believing they were pursuing a beaten enemy, moved through heavily wooded terrain in four disconnected columns. Moreau ambushed the Austrians as they emerged from the Ebersberg forest while launching Antoine Richepanse's division in a surprise envelopment of the Austrian left flank. Displaying superb individual initiative, Moreau's generals managed to encircle and smash the largest Austrian column.

Étienne Clavier (26 December 1762 in Lyon – 18 November 1817 in Paris) was a French Hellenist and magistrate.

The son of a wealthy merchant of Lyon, he made early studies of the Classical languages, followed by studies of law in Paris. In 1788 he purchased a commission as conseiller au Châtelet of which he was soon deprived during the French Revolution. He entered the magistracy under the Directoire, serving as a judge in the criminal tribunal of the Seine, where he made himself prominent by the independence of his character in the trial of General Moreau. Pressured by Joachim Murat, who urged him to pronounce the capital sentence, with the assurance that Napoleon would grant clemency, he made the famous reply, "Et à nous, qui nous la fera?" He was finally discharged from his post in the reorganization of the tribunals of 1811.
