In short
In mid-December 1944, Nazi Germany launched a surprise offensive through Belgium's Ardennes forest, hoping to split Allied forces and force a negotiated peace. The attack caught American and British commanders off-guard, but failed to achieve its objectives after six weeks of brutal fighting. It was the largest battle on the Western Front and effectively marked the beginning of Germany's final defeat.
How it unfolded.
The five-minute version
What actually happened.
The Battle of the Bulge, also known as the Ardennes Offensive and referred to by the Germans as Unternehmen Wacht am Rhein, was an offensive campaign on the Western Front during the Second World War, taking place from 16 December 1944 to 25 January 1945. It was launched through the densely forested Ardennes region of eastern Belgium and northern Luxembourg and was intended to stop Allied use of the Belgian port of Antwerp and to split the Allied lines, allowing the Germans to encircle and destroy each of the four Allied armies and force the western Allies to negotiate a peace treaty in the Axis powers' favor.
