Answer:
Battle of the Bulge was the last major German offensive.
Step-by-step explanation:
As the war was progressing in western Europe and the Germans were being pushed back, Hitler and the German Military Command were looking for some way to stop the advance of the allies. While the command was not in agreement, Hitler felt that pushing back through the Ardennes in Belgium in a similar manner to the World War 1 German army would be effective and historically significant. He ordered the attack, expending the last of his military's offensive capability on pushing through in a final attack. The battle was intense and grueling, but the Germans were ultimately pushed back and lost the battle, crippling them for the rest of the war and increasing the pace with which they were overtaken in the long run.
