The Wikipedia article of the day for October 14, 2018 is Battle of Hochkirch.
The Battle of Hochkirch took place on 14 October 1758 during the Third Silesian War, part of the Seven Years’ War. After several weeks of maneuvering for position, an Austrian army commanded by Lieutenant Field Marshal Leopold Joseph von Daun surprised the Prussian army commanded by Frederick the Great. The Austrians overwhelmed the Prussians and forced a general retreat from the village of Hochkirch, 9 kilometers (6 mi) east of Bautzen, Saxony. Most historians consider the battle one of Frederick’s greatest blunders. Contrary to the advice of his subordinates, he refused to believe that the cautious Daun would engage him in battle. After a pre-dawn attack, Frederick lost over 30 percent of his army, 5 generals, 70 munitions wagons, and his artillery park. Daun failed to pursue the retreating Prussians, allowing the entire force to escape and regain the momentum over the winter.
