Battle context

The Battle of Náchod on 27 June 1866 was the first major action of the Austro-Prussian War, opening the Prussian advance into Bohemia from Silesia. Steinmetz's 5th Corps secured high ground near Náchod and repulsed repeated Austrian attacks by the 6th Corps under Von Ramming, inflicting casualties of 5,719 against a Prussian loss of 1,122. The lopsided casualty ratio was not incidental: it reflected a decisive technological disparity. The Prussian needle gun, a breech-loading rifle that could be loaded and fired from a prone position, allowed infantry to sustain a higher rate of fire with greater cover, while Austrian troops armed with muzzle-loading rifles were forced to stand to reload and were cut down in successive costly attacks. Náchod established early in the war that Austrian tactical doctrine of frontal assault could not overcome this firearm advantage, a pattern that would recur in subsequent engagements of the campaign.
