Levin August, Count von Bennigsen fell upon the 17,000 soldiers of Ney's VI Corps with 63,000 Russians on 5 June 1807. At the Battle of Guttstadt-Deppen, Ney fought a brilliant rear guard action before retreating behind the Pasłęka (Passarge) River. The French lost 400 killed and wounded plus 1,642 captured, while inflicting 2,500 casualties on their adversaries. At this time, Marchand's division included the 6th Light again. Marchand's division was deployed north of Dobre Miasto (Guttstadt) while Baptiste Pierre Bisson defended to the south. The two divisions gave ground slowly, relying on heavy skirmisher lines. Amazingly, Ney still held his ground to the east of the Passarge on the morning of the 6th. Adroit French generalship and Russian mistakes allowed the French to escape across the river that day.
