b) Battle of the Bulge

The Battle of the Bulge, fought in the winter of 1944-1945, was the last major German offensive on the Western Front in World War II. This surprise attack in the densely forested Ardennes region of Belgium and Luxembourg caught the Allied forces off guard, leading to a brutal and costly battle in harsh winter conditions. The eventual failure of this German offensive marked a significant turning point, hastening the end of the war in Europe.
