Battle of Jena–Auerstedt
After Prussia lost the Battle of Jena–Auerstedt in late 1806, French troops marched north into Prussian Pomerania. Fortified Stettin (Szczecin) surrendered without battle, and the province became occupied by the French forces. Kolberg resisted, and the implementation of a French siege was delayed until March 1807 by the freikorps of Ferdinand von Schill operating around the fortress and capturing the assigned French commander of the siege, Victor-Perrin. During these months, the military commander of Kolberg, Lucadou, and the representative of the local populace, Nettelbeck, prepared the fortress's defensive structures.
