The Battle of Allenstein, also known as the Battle of Jonkowo was a military engagement during the early stages of the 1807 Fourth Coalition Napoleonic campaign in Poland. While the battle resulted in a French field victory and allowed for a successful pursuit of the Russian army, it failed to produce the decisive engagement that Napoleon was seeking.
The Battle of Czarnowo on the night of 23–24 December 1806 saw troops of the First French Empire under the eye of Emperor Napoleon I launch an evening assault crossing of the Wkra River against Lieutenant General Alexander Ivanovich Ostermann-Tolstoy's defending Russian Empire forces. The attackers, part of Marshal Louis-Nicolas Davout's III Corps, succeeded in crossing the Wkra at its mouth and pressed eastward to the village of Czarnowo. After an all-night struggle, the Russian commander withdrew his troops to the east, ending this War of the Fourth Coalition action. Czarnowo is located on the north bank of the Narew River 33 kilometres (21 mi) north-northwest of Warsaw, Poland.

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.

The Siege of Graudenz was a siege during the Napoleonic Wars between 22 January and 11 December, 1807. As part of the War of the Fourth Coalition the Prussian fortress at Graudenz in West Prussia was besieged by forces of the French Empire and its allies. The garrison, commanded by General Wilhelm René de l'Homme de Courbière, withheld blockade and siege for some 11 months, long past the formal Peace of Tilsit. The French abandoned the siege after the borders between Prussia and the new Duchy of Warsaw were defined; Graudenz staying a Prussian possession until after World War I.

In the Battle of Guttstadt-Deppen on 5 and 6 June 1807, troops of the Russian Empire led by General Levin August, Count von Bennigsen attacked the First French Empire corps of Marshal Michel Ney. The Russians pressed back their opponents in an action that saw Ney fight a brilliant rearguard action with his heavily outnumbered forces. During the 6th, Ney successfully disengaged his troops and pulled back to the west side of the Pasłęka (Passarge) River. The action occurred during the War of the Fourth Coalition, part of the Napoleonic Wars. Dobre Miasto (Guttstadt) is on Route 51 about 20 kilometers (12 mi) southwest of Lidzbark Warmiński (Heilsberg) and 24 kilometers (15 mi) north of Olsztyn (Allenstein).

In the siege of Hamelin or siege of Hameln, First French Empire forces captured the fortress of Hamelin from its garrison composed of troops from the Kingdom of Prussia. The siege was begun by the VIII Corps under French Marshal Édouard Adolphe Casimir Joseph Mortier. The marshal initially left General of Division Jean-Baptiste Dumonceau in charge of operations. General of Division Anne Jean Marie René Savary soon arrived to conduct negotiations with the Prussian commander General Karl Ludwig von Lecoq, who was quickly persuaded to surrender. Technically, the operation from the War of the Fourth Coalition was a blockade because a formal siege never took place. Hamelin is located 36 kilometers southwest of Hanover.

The twin battles of Jena and Auerstedt were fought on 14 October 1806 on the plateau west of the river Saale in today's Germany, between the forces of Napoleon I of France and Frederick William III of Prussia.

In the Battle of Mohrungen on 25 January 1807, most of a First French Empire corps under the leadership of Marshal Jean-Baptiste Bernadotte fought a strong Russian Empire advance guard led by Major General Yevgeni Ivanovich Markov. The French pushed back the main Russian force, but a cavalry raid on the French supply train caused Bernadotte to call off his attacks. After driving off the cavalry, Bernadotte withdrew and the town was occupied by the army of General Levin August, Count von Bennigsen. The fighting took place in and around Morąg in northern Poland, which in 1807 was the East Prussian town of Mohrungen. The action was part of the War of the Fourth Coalition in the Napoleonic Wars.

The Battle of Ostrołęka was fought on 16 February 1807 between a First French Empire force under General of Division Anne Jean Marie René Savary and a Russian force under Lieutenant General Ivan Essen. The French defeated the Russians and forced them to retreat to the east to Wyoki Mazowiecki. Weather conditions caused both sides to go into winter quarters immediately after the battle, which occurred during the War of the Fourth Coalition, part of the Napoleonic Wars. Ostrołęka is located in the northeast part of modern Poland, but in 1807 it belonged to the Kingdom of Prussia.

The Capitulation of Pasewalk on 29 October 1806 resulted in the surrender of Oberst (Colonel) von Hagen's 4,200 Prussian soldiers to an inferior force of two French light cavalry brigades led by Generals of Brigade Édouard Jean Baptiste Milhaud and Antoine Lasalle.

As Emperor Napoleon I of France's Grande Armée advanced north through the Frankenwald it struck the left wing of the armies belonging to the Kingdom of Prussia and the Electorate of Saxony, which were deployed on a long front. Schleiz is located 30 kilometers north of Hof and 145 kilometers southwest of Dresden at the intersection of Routes 2 and 94.
In the Capitulation of Stettin on 29–30 October 1806, Lieutenant General Friedrich Gisbert Wilhelm von Romberg surrendered the garrison and fortress to a much smaller French light cavalry brigade led by General of Brigade Antoine Lasalle. This event was one of a number of surrenders by demoralized Prussian soldiers to equal or inferior French forces after their disastrous defeat at the Battle of Jena-Auerstedt on 14 October. Stettin, now Szczecin, Poland, is a port city on the Oder River near the Baltic Sea, about 120 kilometres (75 mi) northeast of Berlin.

The Great Sortie of Stralsund was fought in the Franco-Swedish War on 1–3 April 1807, in Swedish Pomerania. A French army under Édouard Mortier invaded Swedish Pomerania in early 1807 and initiated a blockade of the Swedish town of Stralsund, to secure the French rear from enemy attacks. After several smaller sorties and skirmishes around Stralsund, Mortier marched part of his army to support the ongoing Siege of Kolberg, leaving only a smaller force under Charles Louis Dieudonné Grandjean to keep the Swedes at check. The Swedish commander Hans Henric von Essen then commenced a great sortie to push the remaining French forces out of Swedish Pomerania. The French fought bravely on 1 April at Lüssow, Lüdershagen and Voigdehagen, but were eventually forced to withdraw; the Swedes captured Greifswald the next day, after a brief confrontation. The last day of fighting occurred at Demmin and Anklam, where the Swedes took many French prisoners of war, resulting in the complete French withdrawal out of Swedish Pomerania—while the Swedes continued their offensive into Prussia. After two weeks Mortier returned and pushed the Swedish forces back into Swedish Pomerania. After an armistice the French forces once again invaded, on 13 July, and laid siege to Stralsund, which they captured on 20 August; all of Swedish Pomerania was captured by 7 September, but the war between Sweden and France continued until January 6, 1810, when the Swedes were finally forced to sign the Treaty of Paris.

The Siege of Stralsund lasted from 24 July to 24 August 1807 and saw troops from the First French Empire twice attempt to capture the port city from Lieutenant General Hans Henric von Essen's 15,000-man Swedish garrison. Early that year, Marshal Édouard Adolphe Casimir Joseph Mortier blockaded the city for two months before he was called elsewhere. In his absence, the Swedes drove back the inferior blockading force. After Mortier returned and pushed Essen's troops back in turn, the two sides quickly concluded an armistice. The truce was later repudiated by King Gustav IV Adolf of Sweden, and Marshal Guillaume Marie Anne Brune then led 40,000 French, German, Spanish, Italian and Dutch soldiers against the fortress. Fearfully outnumbered, the Swedes abandoned the Baltic Sea port of Stralsund to the Franco-Allies in the action during the War of the Fourth Coalition, part of the Napoleonic Wars. As a consequence, Sweden also lost the nearby island of Rügen.

The Battle of Waren-Nossentin on 1 November 1806 saw soldiers of the Kingdom of Prussia led by August Wilhelm von Pletz and Ludwig Yorck von Wartenburg fight a rear guard action against troops of the First French Empire commanded by Marshal Jean-Baptiste Bernadotte.

Waren lies on the northern end of Lake Müritz, about 70 kilometres (43 mi) southeast of Rostock. Nossentin is a small village on the Fleesen See about 15 kilometres (9 mi) due west of Waren.
