What battle marked the final german offensive in world war 2?

The Battle of the Bulge was the last German offensive in world war 2.

The Battle of the Bulge was not a single battle, but a major push (the Ardennes Offensive) by the German army during the last winter of World War II. Facing Allied advances across a wide front, Hitler ordered a concentrated attack to drive toward the Dutch port of Antwerp through the Ardennes Forest. It was the last major German offensive of the war.

In December, 1944 the Germans attacked a weak area of the allied lines. Their intention was to break through, split the American and British armies, and capture Antwerp, Belgium thus cutting off the British from supplies and reinforcements. They hoped to force the evacuation or surrender of the British forces and that that would force America to make peace. They would then have been able to turn all their strength to defending against the Russians. It didn't work though. The allied lines held, although they were pushed back in a broad semicircle, or bulge, in the line, hence the name of the battle.

The main thrust of the offensive was a two-pronged Panzer attack on the weak points of the Allied lines. It is also noted for the German deception of using captured US vehicles and uniforms to infiltrate the American lines.
