September 4th 1870. Only two month of war were enough for Prussia and its Germanic allies to induce Napoleon III to abdicate in Sedan.
The Republicans refuse the defeat, proclaim the 3rd Republic, form the government of the national Defence and call the French population to rise up in arms. The objective: to burn in enthusiasm, like it happened in 1792. They are determined to push back the coalition of the German States. The fight continues.
Too disorganised, the French Army, made up of the mobile national Guard and the infantry cannot prevent the German progression. September 19th, Paris is besieged. In the capital more than two millions of people need to be feed, among them 500 000 soldiers.above from blog i like the things i like, check it out.
The government, which found refuge in Tours, charge General Trochu of the defence of Paris. He chooses Decrot to command the troupes de ligne and asks him to work out a plan in order to eliminate the German presence. The day of the offensive is fixed on the 28th of November. The breakthrough has to take place in the south-east of Paris. The objective is to allow the Parisian troops to get Fontainbleau where a new army should soon arrive on the Loire river
November 28th the troops are ready. The Marne must be crossed from Joinville and the contact with the enemy must be carried out in Champigny, Bry and Villiers. A first bridge is built but an unexpected flood from the Marne destroys it. General Ducrot decides to postpone the offensive. But the enemy is not naive. Well positioned on the hillsides of Chennevières and Champigny, he had the chance to observe the troop's movements towards Joinville, as well as the first attempt to get over the river which separates them .Immediately a Saxon division receives the order to reinforce the Würtemberger who occupies Champigny and its surroundings. In Thiais, Hay and Choisy-le-Roi, the in charged Generals the operations of the diversionary move, are not warned of the postponement of the offensive. November 29th they literally run into the enemy's arm for a huge lost.
