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). The fighting occurred along Route 580 which runs southwest from Guttstadt to Kalisty
