Origins & Early Life

The Battle of Jena–Auerstedt was fought on Tuesday 14 October 1806, near Jena and Auerstedt (then in the Duchy of Saxe-Weimar and Kingdom of Prussia, now in Thuringia and Saxony-Anhalt, Germany), being the decisive engagement of the War of the Fourth Coalition. The Grande Armée under the command of Emperor Napoleon I defeated a combined Prussian and Saxon army. One force was an imperial French force under the command of Napoleon I at Jena, while the other comprised an imperial French corps under the command of Marshal Louis-Nicolas Davout at Auerstedt. The opposing forces consisted of a Prussian army under the command of Prince Hohenlohe at Jena, and the main Prussian army under the command of Duke Charles William Ferdinand and King Frederick William III at Auerstedt. The Prussians did not forget the military glory of Frederick the Great and venerated it, but by the time of the war, changes were needed for victory, despite the fact that Prussia showed itself well in the French Revolutionary Wars.

Career & Major Achievements

By 1806, Prussian military doctrines had been unchanged for more than 50 years—tactics were monotonous, and the wagon system was obsolete. The Prussian musket of 1806 (the 1754 model) was called "the worst in Europe" by one authority; there were many recruited non-Prussians in the royal army. At the same time, Napoleon's army was recently reorganized according to the advanced corps system, which the French Emperor improved greatly by 1805, who also had such tactics as la maraude at hand. And although the Prussian cavalry was better than the French, and the infantry was a very formidable force, this did not compensate for the shortcomings. Thus at Jena and Auerstedt the backwardness of the Prussian Army became apparent.

Enduring Legacy & Impact

At Jena the French were led by Napoleon himself, and at Auerstedt they were led by one of the most outstanding commanders of the Napoleonic Wars, Louis-Nicolas Davout. The battle of Jena took the Prussian supreme commander there, Prince of Hohenlohe-Ingelfingen, by surprise due to his misorientation and ignorance of the enemy. Due to this incompetence, the Prussians fought a series of isolated, disjointed engagements, unconnected by a unified plan. From beginning to end, Hohenlohe remained disoriented regarding the enemy's strength and direction of advance, and not only did not find time to maintain control of the battle but was unable to even organize an adequate retreat; whilst Napoleon showed firm will at Jena, skillfully taking advantage of both the weather conditions (fog) and the rugged terrain (see Advantage of terrain) when his troops gradually entered the battle from the march. At Auerstedt, Davout, at the first sign of the enemy's appearance, rapidly analysed the area, took an advantageous defensive position, and quickly brought up and deployed all his forces on the battlefield.
