想必这就是大家都很陌生的耶拿之战

背景：The battles began when elements of Napoleon's main force encountered Hohenlohe's troops near Jena. Initially only 48,000 strong, the Emperor took advantage of his carefully planned and flexible dispositions to rapidly build up a crushing superiority. The Prussians were slow to grasp the situation, and slower still to react. Before Ruchel's 15,000 men could arrive from Weimar, Hohenlohe's force was routed. Nevertheless, it was a fierce battle, and Napoleon mistakenly believed that he had faced the main body of the Prussian army.

Although Prussia had begun its mobilization almost a month before France, Napoleon had kept a high state of readiness after the Russian refusal to accept the peace from the Third Coalition. Napoleon conceived a plan to force Prussia into a decisive battle, like Austerlitz, and pre-empt the Prussian offensive. Napoleon had a major portion of his Grande Armée in position in present day Baden-Württemberg in southwest Germany, and thus decided on a northeast advance into Saxony and onto Berlin.
