The 'Battle of Beaumont' on
August 30 1870 was a defeat for the French during the
Franco-Prussian War.
It was fought between Fifth French Corps d'Armee under General
Pierre Louis Charles de Failly, and the IV and XII (Royal Saxon) Army Corps under King
George of Saxony (the XII Army Corps was all-Saxon, while the IV Army Corps was a mix of regiments from
Anhalt,
Prussian Saxony and the
Thuringian states). The French were surprised in their cantonments and driven back upon Monzon, with losses of 4,800 men and 42 guns to the Germans' 3,500.
