The division took part in the Invasion of Poland 1939 as part of Army Group South, but was transferred to garrison the West Wall before the end of the campaign. In 1940 it joined the invasion of Norway, most famously sending its 139th Mountain Regiment under General Eduard Dietl to seize the ice-free Arctic port of Narvik. The Allies briefly managed to take the town back, but abandoned it to the Germans after the invasion of France.
