The siege of Stralsund lasted from 24 July to 24 August, 1807, and saw troops from the

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
.

Prelude

Sweden was established in

When

Napoleon Bonaparte started to expand eastwards in the Napoleonic Wars, the Swedish Empire initially maintained a neutral stance. In 1805, Gustav IV Adolf of Sweden entered the War of the Third Coalition on the anti-French side, primarily to strip Napoleon's ally Denmark of Norway. His Norwegian ambitions were thwarted by several military and diplomatic setbacks.[6]

The blockade

General of Division Charles Louis Dieudonné Grandjean's division crossed the Peene at Anklam, driving back the Swedish outposts. To the west, General of Division Pierre Louis Dupas' division crossed the stream unopposed near Demmin. On the 29th, Mortier's two divisions appeared before the port and on 30 January began the blockade.[9]

For the next two months, the two sides fought a number of skirmishes as the French strengthened their lines of investment. Without control of the island of Rügen, the French were unable to interrupt Stralsund's sea communications and were harassed by Swedish gunboats. During the blockade, one French cavalry and three infantry regiments were taken from Mortier to fight against the Russians in Poland and replaced by troops from the Kingdom of Holland.[9]

On 29 March, Mortier received orders to leave Grandjean's division to maintain the blockade and march to assist in the

Stettin on the Oder, arriving there on the 7th. Mortier retraced his steps and by 13 April had assembled 12,000 to 13,000 men at Stettin, about the same number as Essen. In very wet weather, Mortier began pressing Essen back to Anklam.[10] On 16 April, Mortier defeated the Swedes in the Battle of Belling.[11] The next day, Essen retreated to the north bank of the Peene.[10]

Beginning on 18 April, the French and Swedish forces arranged the truce of Schlatkow.

King Gustav IV Adolf landed in Stralsund on 12 May, and denounced the truce on 3 July.[8] By this time, the Treaties of Tilsit had just deprived Sweden of all her allies but Great Britain.[6] King Gustav IV Adolf however viewed Napoleon as the "monster of the apocalypse" and was unwilling to compromise on his anti-French policies.[13]

On 24 July, French Marshal Guillaume Brune attacked the Swedish positions on the Peene river[8] and reoccupied the investing lines around Stralsund. Reinforced by troops from the failed siege of Kolberg, Brune massed a total of 40,000 men. His French troops included General of Division Jean Boudet's 7-battalion French infantry division of 7,773 infantry and 200 artillerymen and General of Division Gabriel Jean Joseph Molitor's 8-battalion French infantry division of 8,712 infantry and 205 gunners. The Dutch contingent had General of Division Jean-Baptiste Dumonceau's 11-battalion infantry division of 9,924 foot soldiers and 570 gunners, General of Division Henri Gatien Bertrand's 6-battalion infantry division of 3,932 infantry and 159 artillerymen, and General of Division Carteret's 5-squadron cavalry brigade of 1,112 troopers.[14]

Brune's Spanish allies included General

Duchy of Nassau, three battalions.[14]

The 15,000 Swedish defenders included three Finnish battalions, Pommeranian Landwehr garrison troops, one battalion of the King's Household Infantry Regiment and one battalion of the Engelbrechten Infantry Regiment. There were 500 cannons in the fortress. Subordinate to Essen were Lieutenant General Armfelt, General-Major Vegesack, and General-Major Peyron.[14] Gustav IV Adolf left the town on 20 August.[8] Deciding that resistance was useless, the Swedes spiked the cannon and burned the gun carriages. They evacuated the port and transported the powder and shot to Rügen. During the second siege, the Franco-Allies lost 38 officers and 960 soldiers killed, wounded, missing, or died of illness. Swedish losses are unknown.[14] Stralsund and Rügen were surrendered to France in the course of an armistice.[7] Stralsund was handed over to the French on 24 August and Rügen on 7 September 1807.[8]

On 25 August,

General of Brigade François Nicolas Fririon and naval Captain Peytes de Montcabrié attacked the fortified island of Dänholm near Rügen. The 1,200-man and two-gun force comprised one battalion of the 30th Line Infantry Regiment, artillery, sappers, pontonniers, miners, and sailors of the Imperial Guard. The successful operation cost the French 15 killed and 26 wounded.[15] The 600[16] to 800[17] Swedish defenders lost between 26[18] and 125[19] men in dead and wounded, while between 300[18] and 517 were captured. Eight fortress guns and six field pieces also fell into French hands.[20]

Aftermath

After Sweden was driven out of northern Germany in 1807, she became subject to attacks from

Denmark-Norway and the Russian Empire in 1808. Military mismanagement and lack of support led to Gustav IV Adolf being arrested on 13 March 1809 in the course of an insurrection. He was deposed in May and he and his family were expelled in December after Sweden lost a third of its realm in the Treaty of Fredrikshamn.[6]

French occupation of Stralsund was temporarily interrupted when a Prussian freikorps under Ferdinand von Schill seized the city in May 1809, but after a few days it was recaptured in the Battle of Stralsund.[7] When the Napoleonic Wars were concluded by the Congress of Vienna in 1815, Stralsund along with all of Swedish Pomerania became part of the Prussian Pomerania Province.
