The siege of Kolberg took place from March to 2 July 1807 during the War of the Fourth Coalition, part of the Napoleonic Wars. An army of the First French Empire and several foreign auxiliaries of France besieged the fortified town of Kolberg, the only remaining Prussian-held fortress in the Province of Pomerania. The siege was not successful and was lifted upon the announcement of the Peace of Tilsit.
