The War of the Third Coalition was a European conflict lasting from 1805 to 1806 and was the first conflict of the Napoleonic Wars. During the war, France and its client states under Napoleon I and its ally Spain opposed an alliance, the Third Coalition, which was made up of the United Kingdom, the Austrian Empire, the Russian Empire, Naples, Sicily, and Sweden. Prussia remained neutral during the war.
The Battle of Ulm on 16–19 October 1805 was a series of skirmishes, at the end of the Ulm Campaign, which allowed Napoleon I to trap an entire Austrian army under the command of Karl Freiherr Mack von Leiberich with minimal losses and to force its surrender near Ulm in the Electorate of Bavaria.
The Battle of Caldiero took place on 30 October 1805, pitting the French Armée d'Italie under Marshal André Masséna against an Austrian army under the command of Archduke Charles, Duke of Teschen. The French engaged only some of their forces, around 33,000 men, but Archduke Charles engaged the bulk of his army, 49,000 men, leaving out Paul Davidovich's corps to defend the lower Adige and Franz Seraph of Orsini-Rosenberg's corps to cover the Austrian right against any flanking maneuvers. The fighting took place at Caldiero, 15 kilometres east of Verona, during the War of the Third Coalition, part of the Napoleonic Wars.
The Battle of Sacile on 16 April 1809 and its companion Clash at Pordenone on 15 April saw an Austrian army commanded by Archduke John of Austria defeat a Franco-Italian army led by Eugène de Beauharnais and force it to retreat. Sacile proved to be the most notable victory of John's career. The action took place east of the Livenza River near Sacile in modern-day Italy during the War of the Fifth Coalition, part of the Napoleonic Wars.
The Battle of Elchingen, fought on 14 October 1805, saw French forces under Michel Ney rout an Austrian corps led by Johann Sigismund Riesch. This defeat led to a large part of the Austrian army being invested in the fortress of Ulm by the army of Emperor Napoleon Bonaparte of France while other formations fled to the east. Soon afterward, the Austrians trapped in Ulm surrendered and the French mopped up most of the remaining Austrian forces, bringing the Ulm Campaign to a close.
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:
Baron Franjo Jelačić Bužimski was a Croatian military officer and nobleman, a member of the House of Jelačić. He began his service in the Habsburg army as a Grenz infantry officer and fought against the Ottoman Empire. During the French Revolutionary Wars he received promotion to the rank of general officer and won an outstanding victory at Feldkirch. His later career proved that his martial abilities were limited. He twice led independent division-sized forces in the Napoleonic Wars, with unhappy results. He was Proprietor (Inhaber) of an Austrian infantry regiment from 1802 until his death.
Johann Sigismund Graf von Riesch joined the army of Habsburg Austria as a cavalry officer and, during his career, fought against the Kingdom of Prussia, Ottoman Turkey, Revolutionary France, and Napoleon's French Empire. He became a general officer during the French Revolutionary Wars and held important commands during the War of the Second Coalition. He displayed a talent for leading cavalry formations, but proved less capable when given corps-sized commands. During the 1805 Ulm Campaign in the Napoleonic Wars, the French badly defeated his corps and forced it to surrender soon afterward. From 1806 to his death in 1821, he was the Proprietor (Inhaber) of an Austrian cavalry regiment.

Eugène crushed Gyulai's division in a pitched battle near Tarvisio, then an Austrian town known as Tarvis. At nearby Malborghetto Valbruna and Predil Pass, small garrisons of Grenz infantry heroically defended two forts before being overwhelmed by sheer numbers. The Franco-Italian capture of the key mountain passes allowed their forces to invade Austrian Kärnten during the War of the Fifth Coalition. Tarvisio is located in far northeast Italy, near the borders of both Austria and Slovenia.
Alois Graf von Gavasini led a combat brigade in the armies of Habsburg Austria and the Austrian Empire during a remarkable number of battles in the French Revolutionary Wars and Napoleonic Wars. A native of Bonn, he offered his services to Austria and won an award for bravery in 1790. While a field officer in the Italian campaign, he led the rear guard at Primolano in September 1796. Badly outnumbered by the French, he and his soldiers put up a vigorous fight until he was wounded and captured. At Arcole in November 1796, he commanded a brigade on the field of battle against Napoleon Bonaparte's French army. Promoted to general officer in the spring of 1800, he led a powerful brigade at Hohenlinden during that year's fall campaign in Bavaria. Though the battle ended in a decisive defeat, Gavasini's troops fought well before being forced to retreat. The 1805 campaign in Italy found him directing a reserve brigade at Caldiero. After briefly retiring, the warrior returned to lead a brigade at the battles of Sacile, Piave River, and Graz during the 1809 war. That year he retired from the army and did not return.
