Zündnadelgewehr
Although occupying a strong position Iser Army was beaten by two Prussian divisions due to strategic and tactical blunders. Tardy staff work at main headquarters caused Clam-Gallas to believe he would be supported by the Austrian main army, as was originally planned, but which made him fight the battle unsupported. The Saxon army camping some ten kilometers south of their designed position in the Austrian line, made them late and caused a hole in the battle line, which the Prussians exploited to their fullest. Lastly the superior Dreyse needle gun, gave the Prussians a huge tactical advantage over the Austrian storm tactics.
