The Battle of Náchod (German: Nachod) 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 Náchod 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.
