Operation Northwind (German: Unternehmen Nordwind) was the last major German offensive of World War II on the Western Front.
Northwind was launched to support the German Ardennes offensive campaign in the Battle of the Bulge, which by December 1944 had decisively turned against the German forces.
It began on 31 December 1944 in Rhineland-Palatinate, Alsace and Lorraine in southwestern Germany and northeastern France, and ended on 25 January 1945.
The German offensive was an operational failure, with its main objectives not achieved.
