ケーニヒグレーツの戦い
The course of the war, however, turned to Italy's favour by Prussian victories in Bohemia, especially the decisive Battle of Königgrätz (or Sadowa) on 3 July. The Austrians were compelled to redeploy one of their three army corps from Italy to Vienna. The remaining Austrian forces in the theatre concentrated their defences around Trentino and Isonzo.
