Battle of Sedan in the context of "Napoleon III"

The Government of National Defense (French: Gouvernement de la Défense nationale) was the first government of the Third Republic of France from 4 September 1870 to 13 February 1871 during the Franco-Prussian War. It was formed after the proclamation of the Republic in Paris on 4 September, which in turn followed the surrender and capture of Emperor Napoleon III by the Prussians at the Battle of Sedan. The government, headed by General Louis Jules Trochu, was under Prussian siege in Paris. Breakouts were attempted twice, but met with disaster and rising dissatisfaction of the public. In late January the government, having further enraged the population of Paris by crushing a revolutionary uprising, surrendered to the Prussians. Two weeks later, it was replaced by the new government of Adolphe Thiers, which soon passed a variety of financial laws in an attempt to pay reparations and thus oblige the Prussians to leave France, leading to the outbreak of revolutions in French cities, and the ultimate creation of the Paris Commune.

The Army of Châlons (French: Armée de Châlons) was a French military formation that fought during the Franco-Prussian War of 1870. Formed in the camp of Châlons on August 17, 1870, from elements of the Army of the Rhine which the formation was issued from, the Army of Châlons was engaged in combats of Beaumont and Sedan while disappearing during the capitulation of September 2, 1870.

Marie Edme Patrice Maurice de MacMahon, marquis de MacMahon, duc de Magenta (French: [patʁis də makma.ɔ̃]; 13 June 1808 – 17 October 1893), was a French general and politician who served as President of France from 1873 to 1879. He was elevated to the dignity of Marshal of France by Napoleon III.

MacMahon led the main French army in the Franco-Prussian War in 1870. He was trapped and wounded at the Battle of Sedan in September 1870, in part because of his confused and indecisive strategic planning. The army, including MacMahon and Emperor Napoleon III, surrendered to the Germans. Thus the Emperor was deposed and the French Third Republic was proclaimed. After convalescing, MacMahon was appointed head of the Versailles army, which suppressed the Paris Commune revolt in May 1871 and set the stage for his political career.

The Siege of Metz was a siege fought during the Franco-Prussian War from 19 August to 27 October 1870, and ended in a decisive allied German victory.

The French Army of the Rhine under François Bazaine retreated into the Metz fortress after its defeat by the Germans at the Battle of Gravelotte on 18 August 1870. The fortress was promptly surrounded by German forces under Prince Friedrich Karl of Prussia. The French Army of Châlons was sent to relieve the Army of the Rhine but was itself encircled and annihilated by the German armies at the Battle of Sedan on 1–2 September.

Sedan (French pronunciation: [sədɑ̃] ) is a commune in the Ardennes department and Grand Est region of north-eastern France. It is also the chef-lieu (administrative centre) of the arrondissement of the same name.

Sedan is notable as the site of two major battles between the armed forces of France and Germany, both of which were won by Germany. The First Battle of Sedan in 1870 sealed the fate of the Second French Empire and paved the way to the foundation of the German Empire, leading to the subsequent annual celebration of "Sedan Day" in Germany. The Second Battle of Sedan in 1940 achieved a decisive breakthrough by Wehrmacht forces in the Battle of France and ultimately led to the collapse of the French Third Republic.

Auguste-Alexandre Ducrot (French pronunciation: [oɡyst alɛksɑ̃dʁ dykʁo]; 24 February 1817 – 16 August 1882) was a French general. Ducrot served in the Crimean War, Algeria, the Italian campaign of 1859, and as a division commander in the Franco-Prussian War.

At the outbreak of the Franco-Prussian War, Ducrot was tasked with overseeing the deployment of French forces due to his familiarity with the terrain near Wissembourg. His unsupported division was surprised and defeated by a large force of Prussians and Bavarians at the Battle of Wissembourg. At the Battle of Sedan on 1 September 1870, he succeeded to command of the French army when Marshal MacMahon was wounded early in the morning. By that time, it was obvious that a disastrous defeat was inevitable. Ducrot summed up the situation with the famous remark:
