No 8. Battle of Ardennes – December 16, 1944 to January 28, 1945
Also known as the Battle of the Bulge, the Battle of Ardennes was a German offensive launched towards the end of World war II in the thick forests of the Ardennes Mountains region of Belgium, France and Luxembourg on the Western Front. The German code name for the offensive was Unternehmen Wacht am Rhein, which meant “Operation Watch on the Rhine” in English. Even with enough intelligence on a possible offensive, the Ardennes Offensive caught the Allies off guard. But still, the offensive was a failure and Germany lost over 100,000 of its men and the Allies lost about 20,000 of theirs.
