1944/1945
In the Soviet summer offensive the division held its lines in heavy fighting until it was ordered to withdraw from Finland, upon the conclusion of a separate armistice between the Finns and the Soviets in September 1944. The 6th SS Mountain Division then formed the rear guard for the three German corps withdrawing from Finland in Operation Birch and from September to November 1944 marched 1,600 kilometers to Mo i Rana, Norway, where it entrained for the southern end of the country. The Norwegian Skil-Battalion unit was then left behind, in accordance with their contracts. They were merged into "SS-und-Schi-Jäger-Polizei-Battalion 506 (mot.) with app. 50% men from different German Police units in South Norway.
The rest of the Division headed for Germany,
After crossing the Skagerrak in a naval convoy, the division briefly refitted in Denmark. The Division's losses were replaced for the greater part of young Volksdeutsche (ethnic Germans) who had received only a brief training and had not volunteered but been drafted to the Waffen SS in the normal conscription procedure. Their fighting value was therefore correspondingly lower than had been the case with the former personnel and naturally lowered the combat abilities of the entire division.
The division was slated for participation in the German offensive in the Ardennes known as the Battle of the Bulge, but did not assemble in Aarhus, Denmark, until 20 December, several days after the attack had already begun.
Instead, the division was allotted to Operation Nordwind in the Low Vosges mountains of southeastern France. Arriving at the front lines just before New Year’s Day. Nord was the largest German division involved in Nordwind, and it had young and fit personnel compared to regular Army outfits. By 2 January, part of the division (SS Gebirgs Regiment 12 and 506th Battalion) went into action against the U.S. 45th Infantry Division, attached to 361st Volksgrenadier Division. For six days the SS men fought in and around the town of Wingen, finally being pushed back by the Americans with most of the battle group killed or captured.
On 16 January, the SS Gebirgs Regiment 11 surrounded six companies of the American 157th Infantry Regiment. The Americans were forced to surrender three days later, losing 482 men. The Nord advanced for four more days before being stopped by American counterattacks.
The Division remained on the western front after the Nordwind offensive, fighting the Americans around Trier and Koblenz on the Moselle River in March before going into 7th Army's reserve in April. By this point the division had lost most of its heavy weapons (officially to fuel shortages) and was grossly understrength. In May 1945, the unit's survivors surrendered to the Americans in Austria.
