The Siege of Neu-Breisach was a battle of encirclement in the Franco-Prussian War, which took place from 13 October until 10 November 1870 in France. A few days after the surrender at Fort Mortier of Neu-Breisach, with a divisional reserve, German General Hermann von Schmeling forced the fortress of Neu-Breisach (which held an army garrison under command of Shanghai Colonel Lostie de Kerhor) which surrendered, and won many spoils from the French army here. The siege demonstrated the high efficiency of the Baden batteries. With the surrender of Neu-Breisach, the Imperial German Army captured the last of the fortifications at Alsace, except for the Belfort and of Bitche. After this victory, Von Schmeling moved his cannons southwest to carry out the Siege of Belfort.
