Origins

The Fourth Coalition (1806–1807) of Prussia, Russia, Saxony, Sweden and the United Kingdom against France formed within months of the collapse of the previous coalition. Following his triumph at the Battle of Austerlitz
Battle of Austerlitz
The Battle of Austerlitz, also known as the Battle of the Three Emperors, was one of Napoleon's greatest victories, where the French Empire effectively crushed the Third Coalition...

 and the subsequent demise of the Third Coalition, Napoleon looked forward to achieving a general peace in Europe, especially with his two main remaining antagonists, Britain and Russia. Meanwhile, he sought to isolate Prussia from the influence of these two powers by offering a tentative alliance, while at the same time seeking to curb Prussia's political and military influence among the German states.

 in January 1806, Britain and the new Whig administration remained committed to checking the growing power of France. Peace overtures between the two nations early in the new year proved intransigent due to the still unresolved outstanding issues that had led to the breakdown of the Peace of Amiens

, a German electorate in personal union with the British monarchy that had been occupied by France since 1803. Dispute over this state would eventually become a casus belli for both Britain and Prussia against France. This issue also dragged Sweden into the war, whose forces had been deployed there as part of the effort to liberate Hanover during the war of the previous coalition. The path to war seemed inevitable after French forces ejected the Swedish troops in April 1806.

 in July 1806, (though these actions are considered part of the tail end of the War of the Third Coalition,) the main conflicts between Britain and France during the Fourth Coalition would involve no direct general military confrontation. Rather, there was an escalation in the ongoing economic warfare between the two powers. With Britain still retaining its dominance of the seas, Napoleon looked to break this dominance (after his defeat of Prussia) with his issuance of the Berlin Decree

. Britain retaliated with its Orders in Council several months later.

In the mean time, Russia spent most of 1806 still licking its wounds from the previous year's campaign. Napoleon had hoped to establish peace with Russia and a tentative peace treaty was signed in July 1806, but this was vetoed by Tsar Alexander I
Alexander I of Russia
Alexander I of Russia , served as Emperor of Russia from 23 March 1801 to 1 December 1825 and the first Russian King of Poland from 1815 to 1825. He was also the first Russian Grand Duke of Finland and Lithuania....

 and the two powers remained at war. Though nominally an ally in the coalition, Russia remained a dormant entity for much of the year (giving virtually no military aid to Prussia in the main battles that October, as Russian armies were still mobilising). Russian forces would not fully come into play in the war until late 1806 when Napoleon entered Poland.

Finally, Prussia had remained at peace with France the previous year, though it did come close to joining the Allies in the Third Coalition. A French corps led by Marshal Bernadotte had illegally violated the neutrality of Ansbach
Ansbach
Ansbach, originally Onolzbach, is a town in Bavaria, Germany. It is the capital of the administrative region of Middle Franconia. Ansbach is situated southwest of Nuremberg and north of Munich, on the Fränkische Rezat, a tributary of the Main river. As of 2004, its population was 40,723.Ansbach...

. In addition, on 15 March 1806 Napoleon elevated his brother-in-law Marshal Joachim Murat

 and Cleves (acquired from Bavaria in return for its receiving Ansbach). Murat exacerbated Prussian enmity by tactlessly ejecting a Prussian garrison that was stationed in his newly acquired realm, prompting a stern rebuke from Napoleon. Relations between France and Prussia quickly soured when Prussia eventually discovered that Napoleon had secretly promised to return sovereignty of Hanover back to Britain during his abortive peace negotiations with the British. This duplicity by the French would be one of the main causes for Prussia declaring war that autumn.
Another cause was Napoleon's formation in July 1806 of the Confederation of the Rhine

The Confederation of the Rhine was a confederation of client states of the First French Empire. It was formed initially from 16 German states by Napoleon after he defeated Austria's Francis II and Russia's Alexander I in the Battle of Austerlitz. The Treaty of Pressburg, in effect, led to the...

The Confederation was above all a military alliance: in return for continued French protection, member states were compelled to supply France with large numbers of their own military personnel (mainly to serve as auxiliaries to the Grande Armée), as well as contribute much of the resources needed to support the French armies still occupying western and southern Germany. Understandably, Prussia was indignant at this increasing French meddling in the affairs of German homogeneity (without its involvement or even consultation) and viewed it as a threat. Napoleon had previously attempted to emolliate Prussian anxieties by assuring Prussia he was not adverse to its heading a North German Confederation
North German Confederation

 and the war party in Berlin, in August 1806 the Prussian king Friedrich Wilhelm III made the decision to go to war independently of any other great power, save the distant Russia. Another course of action might have involved openly declaring war the previous year and joining Austria and Russia in the Third Coalition. In fact, the Tsar had visited the Prussian king and queen at the tomb of Frederick the Great in Potsdam that very autumn, and the monarchs secretly swore to make common cause against Napoleon. Had Prussian forces been engaged against the French in 1805, this might have contained Napoleon and prevented the eventual Allied disaster at Austerlitz. In any event, Prussia vacillated in the face of the swift French invasion of Austria and then hastily professed neutrality once the Third Coalition was crushed. When Prussia did eventually declare war against France in 1806, its main ally the Russians still remained far away remobilising. The electorate of Saxony would be Prussia's sole German ally.

Napoleon could scarcely believe Prussia would be so foolish to take him on in a straight fight with hardly any allies at hand on its side, especially since most of his Grande Armée was still in the heart of Germany close to the Prussian border. He drummed up support from his soldiers by declaring that Prussia's bellicose actions had delayed their phased withdrawal back home to France to enjoy praise for the previous year's victories. Once hostilities seemed inevitable in September 1806, Napoleon unleashed all French forces east of the Rhine, deploying the corps of the Grande Armée along the frontier of southern Saxony. In a preemptive strike to catch the Prussians unaware, the Emperor had the Grande Armée march as a massive bataillon carré (battalion square) in three parallel columns through the Franconian Forest

. Each corps would be in mutual supporting distance of each other, both within the column and laterally to the other columns (once through the difficult passage of the forest), thus allowing the Grand Armée to meet the enemy at any contingency. This strategy was adopted due to Napoleon's lack of intelligence regarding the Prussian main army's whereabouts and uncertainty over his enemy's puzzling maneuvers in their march to face him. The reason for this stemmed mainly from the mutual mistrust within the Prussian high command that had resulted in division among the Prussian commanders over which plan of action for the war would be adopted. Despite the deficiency in pinpointing the main Prussian army's exact position, Napoleon correctly surmised their probable concentration in the vicinity of Erfurt

. At Jena, Napoleon fought only a contingent of the Prussian army. At Auerstedt a single French corps defeated the bulk of the Prussian army, despite being heavily outnumbered. Victory at Auerstedt was all but secured once the Duke of Brunswick (as well as fellow commander Friedrich William Carl von Schmettau) were mortally wounded, and the Prussian command devolved to the less able King. Matters were worsened once the vanquished remnants of the Prussian army from Jena stumbled onto the clash at Auerstedt, further plunging the Prussians' morale and triggering their precipitous retreat. For this conspicuous victory, Marshal Davout was later created the Duke of Auerstedt by Napoleon.
