The ‘Battle of the Bulge’ was a major German offensive that took place in the Ardennes region of Belgium in December 1944. The German offensive was a surprise to the Allies, and it caught them off guard. The Germans were able to advance deep into Allied territory, but they were eventually stopped by Allied forces. The Battle of the Bulge was a costly battle for both sides, but it was a major turning point in the war. It marked the end of the German offensive in the West, and it helped to secure the Allied victory in Europe.
