What is the importance of Battle of the Bulge in terms of WWII?
It was Hitler's last gasp on the Western Front and in World War II in general. His goal was to drive the Allies back and capture the port of Antwerp, then sue for peace and hope the US joined him to fight the Soviets. Talk about a long shot.
His troops achieved initial success but failed to achieve their goal, and were driven back just after Christmas. Hitler's armies posed no serious threat to Allied troops at the conclusion of this battle, and it was just a matter of time before they were defeated.
By using his last remaining troop reserves on the Western Front, it prevented them from being used to halt the Soviet advance, and probably shortened the war.
The Battle of the Bulge was Germany's last attempt to try to have any serious hope of winning the war or of getting a negotiated settlement.
This battle started with a surprise attack by German forces in the winter of 1944. The objective of the German forces was to push through Belgium to the ocean.
Hitler believed that he could split the Allied forces and keep them at bay. If he accomplished that, he thought, he could get a decent settlement instead of having to surrender unconditionally.
The battle has this name because of "bulge" that the Germans created in Allied lines as their initial attacks succeeded.
