イエナ・アウエルシュタットの戦い
In the Capitulation of Erfurt on 16 October 1806 a large body of troops from the Kingdom of Prussia under Lieutenant General the Prince of Orange surrendered to Marshal Joachim Murat of France, at the city of Erfurt (now in Germany). The Prussian soldiers were demoralized by their shattering defeat at the Battle of Jena–Auerstedt on 14 October and unwilling to put up much resistance. The event occurred during the War of the Fourth Coalition, part of the Napoleonic Wars. Erfurt is located on the Gera River about 40 kilometers west of Jena.
