The 'Siege of Belfort' was a lengthy siege during the
Franco-Prussian War. The garrison held out until the armistice between
France and the
German Empire.
The
fall of Strasbourg on
September 28 allowed the German army under
Carl Wilhelm von Werder to move south against the city
Belfort. Upon hearing of the approaching German army,
Pierre Philippe Denfert-Rochereau, commander of Belfort, began constructing fortifications around the city. Werder's forces reached Belfort and invested the city on
November 3. The French offered stubborn resistance and the Germans could not complete an effective encirclement of the city.
General
Charles Denis Bourbaki assembled an army intending to relieve Belfort. On
January 15,
1871 Bourbaki attacked Werder along the
Lisaine River and after a three day battle was repulsed and his army retreated into Switzerland. German forces grew impatient with the length of the siege and on
January 27 General von Tresckow launched an attack on the city which was repulsed and the siege operations resumed.
On
February 15 an armistice had been signed between France and Germany.
Louis Adolphe Thiers, president of the
Government of National Defense sent an urgent message to Denfert-Rochereau ordering him to surrender the fortress. On
February 18 the Belfort garrison marched out of the city and surrendered to the Germans.
