The Battle of Nachod (or Náchod) on 27 June 1866 was the first major action of the Austro-Prussian War. The advance guard of General Karl Friedrich von Steinmetz's 5th Corps occupied some high ground near Nachod as part of a Prussian advance into Bohemia from Silesia. Elements of the Austrian 6th Corps under General Von Ramming came on the scene and attacked the Prussians but were repulsed. As more Austrians arrived, they were ordered into attacks which proved both costly and unsuccessful.
