Wilhelm and Bismarck read the letter and Bismarck accepted it. Wimpffen attempted a last-ditch negotiation maneuver, seeking an "honorable capitulation" over prisoner-of-war status for the Army of Châlons, but Moltke rebuffed him, pointing to the French lack of ammunition and food, the 250,000 troops on the German side against the mere 80,000 fighting for the French and the concentric German position. Wimpffen received only the prolonging of the truce until 0900 on 2 September. By the next day, at 11:30 on 2 September, Wimpffen signed the surrender of himself and the entire "Army of Châlons" to Moltke and the Prussian King. The French soldiers marched under heavy rain to an improvised German POW camp, where they starved for the next week. On 3 September, Napoleon III left for a comfortable captivity in Schloss Wilhelmshöhe near Kassel. The French prisoners of war viewed his departure with indifference. The capture of the French emperor left the Prussians without an opposing government willing to make a quick peace. Indeed, two days after news hit Paris of Emperor Napoleon's III capture, the French Second Empire collapsed in a bloodless revolution, leading to the creation of a Government of National Defense which would carry on the war for five more months. However, the defeat at Sedan and the capture of Napoleon III and France's second line army, and with the first line French Army shut up in Metz, sealed the doom of France and thus decided the outcome of the war in Prussia's favor. By 19 September, the Prussian Third and Fourth Armies went on to besiege Paris. In recognition of the role this battle played in German Unification, many Germans celebrated Sedantag (Day of Sedan) on each 2 September until 1919. The Kaiser himself refused to declare 2 September an official holiday; instead, it became an unofficial day of celebration. The Germans lost 9,942 men, with 1,310 killed, 6,443 wounded and 2,107 missing. The French Army of Châlons suffered 3,220 killed, 14,811 wounded, and 104,000 captured, along with 558 guns. The French army also lost 1,000 wagons and 6,000 horses to the Germans.
