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.
