<em>D. Was Hitler's last chance to defeat the Allies.</em>
Explanation:
The Battle of the Bulge was a very important battle against the Allies and the Germans and was Hitler's last chance to defeat the Allies.
Before the Battle of the Bulge, Allies had recently defeated Germany before and had helped most of Europe against German rule. By then, the Allies thought that Germany had essentially given up and World War II was over, but Hitler had one last plan.
Hitler ended up going forward into the American troops, trying to break the front lines. The Allies were not ready for this and many ended up dying, which caused Germany to go forward. As Germany continued to advance, the American troops finally started pushing the troops back and eventually started getting the upper hand against German troops.
This is a very famous battle because of the small fights that occurred and the courage that was with the American troops. Many of the American troops had to hold out until backup arrived since they were not expecting this attack from Germany. Although Germany caught them by surprise and at first started winning against the Allies, they pushed them back and won the battle.
