 The Austrians took this opportunity to raid Valtellina and Val Camonica (battle of Vezza d'Oglio).The course of the war, however, was to turn in Italy's favor thanks to Prussian victories in Bohemia, especially the decisive Battle of Königgrätz (or Sadowa) on 3 July 1866.The Austrians were compelled to redeploy one of their three army corps from Italy to Vienna.
