Oberst Wolff was the first to force a crossing over the Schelde and Lys rivers during the German invasion of the Low Countries in 1940, and thus contributed decisively to the overall German victory. Under his personal leadership his regiment crossed the Lys near Nevele using inflatable rafts, and about 5000 prisoners were taken during this fight. For these successes Wolff would be awarded the Knight's Cross.
