The Battle of the Bulge is best described as ____ ?

There are many possible ways to describe the Battle of the Bulge. I do not know what specific words your teacher wants to use to describe the battle.  My first choice for how to describe this would be to say that the Battle of the Bulge was Germany’s last-gasp attempt to avert defeat in WWII.

The Battle of the Bulge began in December of 1944.  Months before, the Allies had invaded Europe in the D-Day landings in Normandy.  Over the rest of 1944, they had pushed towards Germany.  The Germans were clearly in danger of losing the war. 

The Battle of the Bulge was Germany’s last effort to stave off defeat. Hitler believed that he could launch a major offensive that would split the British and the American armies apart. Hitler hoped that this would lead to discord between the Allies.  He also hoped that it would make their strategic position untenable. Both of these factors would encourage them to make peace rather than trying to conquer Germany and force them to surrender unconditionally.  The massive offensive succeeded for a while, but strong Allied resistance held the attack until weather improved, allowing Allied air power to help destroy the German advance.

In this way, the Battle of the Bulge, which can also be called the largest single battle American troops have ever been involved in, can be described as Germany’s last-gasp attempt to avoid losing WWII.
